How do I know if my testing system is measuring correctly?
The only way to truly be sure that your testing system is measuring correctly is to have it checked against a known and traceable reference. Instron's calibrations provide such a service. Learn more about calibration.
How do I prove my testing system is giving good results?
The best way to prove that your testing system is giving good results is to check them against traceable and known references and then compare the results with the requirements of recognized and established procedures or standards. This process is known as calibration and verification. Using international standards, such as ISO and ASTM, and reference devices that can be traced back to a National Measurement Institute (NMI) gives you and your customers confidence in the accuracy of the results. Learn more about Instron's calibration services.
How frequently should I have my testing system checked or calibrated?
In many cases, your QA policies, contract requirements, or department procedures will stipulate rules on the frequency of calibration. In other cases, the equipment's operating manual may recommend how often the device should be recalibrated. In practical terms, it is all about risk. The longer the period you leave equipment between calibrations, the greater the risk of something going wrong or not being spotted. Because of this, you will find that many standards, such as ISO and ASTM, either recommend or state mandatory frequencies of calibration for compliance. If you are testing to an ASTM or ISO testing standard (e.g., ASTM E8 or ISO 7500-1), it is worth checking to see if it stipulates maintenance and calibration requirements. Learn more about Instron's calibration services.
How long has Instron been providing accredited calibration services?

The materials testing system calibrations that Instron recommends as standard are load cell (force), speed and displacement, and strain. Learn more about Instron's types of calibrations.
My materials testing system has undergone repairs and updates. Does it need to be recalibrated?
If your materials testing system has undergone a major repair that affects the measuring system, we strongly advise you to arrange for a recalibration. However, if the repair, update, or modification does not affect the measuring system, you probably do not need to recalibrate your tester. If in doubt, do not hesitate to discuss the subject with one of our experts. Please note that some standards do provide guidance and requirements concerning maintenance and repair, so review the standards you are working to for clarification. Learn more about Instron's calibration services.

Both the up and down push button switch indicators on the pendent station light when trying to move the crosshead on a hvl frame. (note this is on the 24v dc system only)
This happens when the overload is tripped on the reversing line starter. Reset the line starter by pressing the button or tab by the overload devise in the electrical box.
I have an auditor asking for software verification documentation and Instron accreditation information. Where can I find this information?
Instron software verification documentation, accreditations and certificates can be viewed and downloaded on our accreditations and certifications page.
The 3-phase crosshead motor on a hydraulic hvl testing frame will not operate.
The motor has an overload protection devise on the 3 phase line starter in the electrical box. Turn off the main power and open the box. At the bottom of the reversing line starter is a reset button, it must be pushed in to reset the devise. At least three different styles of line starters have been used over the years, but all of them have the overload in about the same place.
The 3-phase pump motor on a hydraulic hvl testing frame will not operate.
There are several things to consider here: 1. The controller type 2. The software 3. Power to the pump Check in the following order: 1. Make sure the Control box is on and the machine software is running in a pretest menu. 2. Make sure there is power to the electrical box. 3. Make sure the machine limit switch is not tripped or stuck in the tripped position. 4. Make sure the stop button is reset to the on state (Many machines have a twist to unlock switch). 5. Make sure the machine is not showing an overloaded condition on the input load signal.
The position is not changing on the display when the ram is raised. (string style encoder box devise)
Check to see the string cable from the position devise is attached to the ram assembly. Check the encoder cable connection on both the encoder box and controller for proper installation. Replace the encoder or the encoder board in the controller.
The pump will not come on and all the conditions are met (Mats II controller)
First: The limit switch rod on many of these machines has a dual purpose; if the crosshead has been run up and is resting on the limit it will prevent the pump from coming on. Back the adjustable crosshead off until this limit is no longer tripped.
Second: There is a pica fuse on the MMR rack in the back of the control box for each relay. The fuse is to the lower left of the relay socket on the board. The fuse is a 5 amp - plug in style that looks like a resistor.
The pump will not start on a hvl style machine.

What oil does my BTE, Baldwin or Southwark machine use?
If the machine has the original Helishaw pump one can use Mobile DTE Extra Heavy. This oil is 600 SSU at 100 degrees F. If you tell you oil supplier this information and he can not find Mobile DTE Extra Heavy he should be able to find a substitute.
After opening a procedure on my model dx machine, the pump will not turn on.
The machine frame is not enabled. Enable the machine. For Partner systems, select Machine and then Enable Frame. For Merlin systems, select the Frame icon and Enable Frame. For systems operating with Partner software, the "Enable Frame Timer" setting may be enabled. Verify the status of the "Enable Frame Timer" Check Box in Partner. Select Tools/Configure/Controllers/I5500/Modify. Be sure the "Enable Frame Timer" box is NOT checked.
After starting a procedure on my model dx machine, the live data and live graph appear on the computer monitor but the machine is not moving.
The software could be in Simulation mode. Verify that the lower right corner of the screen does not have the word "SIM". If it does, select Tools/Configure/Simulation and uncheck the "Simulate Test" box.
I am getting this error on my model dx machine: ERROR: System lock up Test will not start Test Aborts Software post and error message stating that communication is lost Transducers will not calibrate Flashing single point LED on Diagnostic display is not present.. How do I resolve this?
Communication between the machine frame and controls is lost.
Back out of the software and then turn the PC off.
Remove power from the 5500 controller box and wait approx. 1 min.
Return power to 5500 controller and wait until the leds on the 5500 controller count down to 2. Then turn PC on and get into the testing software.
I get this error on my model dx machine: test will not start test aborts pump shuts off software post an error message stating "Position loop failure". How do I resolve this?
First check to see if position will read by gently pulling on the string to the position encoder. If position does not read, check the position encoder assembly for damage. If position is reading correctly check to see if the hyrdaulic ram is sitting at the bottom. If the ram is on the bottom start the pump and move the ram up approxiaately 6 mm (.25 in), zero all measurements, and calibrate all transducers.
Software posts an error message stating "Control panel watchdog timeout"
Communication has been lost with the user control panel. Check the cable for the user control panel for damage. If damage is found contact the Instron Hardware Technical Support Department at 800-473-7378.
Can I convert my test results to a rockwell c scale from a tukon micro indentation tester?
NO, both ASTM E-140 and the Wilson Conversion Wall Chart stipulates a minimum load for a Knoop test is 500 grams. To get a Wilson Wall Chart contact the Sales Dept at 800-695-4273.
Can I perform regular tests on my superficial rockwell tester?
No, you can not.
Can I perform superficial tests on my regular Rockwell?
No, you can not.
Can I use a carbide ball indenter on a block that was not calibrated with a carbide ball?
Yes, you can but your reading will be lower, up to 1 point lower than normal.
Can my regular Rockwell tester be modified to perform superficial tests?
No, it can not. Unless it is a model 2000 tester. If it is, then it can be programmed to do superficial tests.
Can my superficial rockwell tester be modified to perform regular tasks?
No, it can not. Unless it is a model 2000 tester. If it is, then it can be programmed to do regular tests.
Do the weights in my dead weight tester actually weigh the amount stamped on them?
No, they do not. They are stacked in a cumulative fashion. For instance, on a regular scale Rockwell tester, the 60kg weight actually weighs 2230g or 1849g (depending on whether your power lever is iron or aluminum), the 100kg weight actually weighs 1600g and the 150kg weight actually weighs 2000g.
Do you have tips on shipping my dashpot or dead weight hardness tester?
First, do not turn the tester on its side, the oil will leak out. Second, remove the weights and pack separately. And last, wrap some foam or bubble wrap around the power lever to prevent it from movement. Yes, it can be strapped to a packing skid, just make sure you don't have any straps laid across the elevating screw. Remember to remove indenters, blocks and anvils as well.
Does the deformation during a test also extend outward?
Yes, so the distance near an edge or an adjacent indent is critical. ASTM recommends the distance from the center of an indentation and the nearest adjacent indentation be 3 times the diameter of the indentation. The distance between the center of an indentation to the nearest edge must be at least 2 ½ times the diameter of the indentation.
How can I get my tukon micro-indentation tester calibrated to read smaller indents?
According to ASTM E384 an indirect verification using standardized test blocks is not recommended for diagonals of less than 20 microns. To receive a copy of ASTM E-384 you may contact ASTM on the WEB at http://www.astm.org
How do I know when my test block is no longer useful?
The useful life of a test block is determined by the population and proximity of the indentations. The distance between the center of any two adjacent indentations shall be at least three times the diameter of the indentation. The distance from the center of any indentation to an edge of the test block or test piece shall be at least two and a half times the diameter of the indentation. Tests are to be taken on the top side of the block only.
How do you determine the material thickness?
Material surrounding the indentation is plastically deformed well below the indentation depth. If the material is too thin the deformation will flow into the anvil which could cause erroneous readings. A Rockwell scale having the appropriate combinations of forces and indenter size must be chosen based on the material thickness and minimum hardness. ASTM recommends the minimum thickness for a ball indenter to be 15 times greater than the depth of penetration of the indent. ASTM recommends a minimum thickness of 10 times greater than the depth of penetration for a diamond indenter. Chart 55 and ASTM E-18 tables 7-10 makes recommendations on the minimum thickness vs hardness. This chart is part of the Wilson Conversion Chart.The Wilson Conversion Chart is available from Sales at 800-695-4273. You can also contact ASTM on the WEB at www.astm.org http://www.astm.org
How do you run the self-test feature on the u-tronics printer?
To use the Self Test feature of the printer, start with the printer power ON, and set the printer to the Offline mode. Offline mode means only the Red light is lit, so if the Green light is ON, press the SEL button to turn it Off. Next, press and hold the LF button, then press the SEL button while still pressing the LF button. The printer should start printing a self test pattern so you can release both buttons once it starts printing. To stop the printing, press the SEL button or you can wait until the printer times out.
How frequently should I have my tester verified or calibrated?
We recommend that it be done annually.
How many tests will a tukon 200 series with a digital filar option store?
It will store up to 1000 hardness values.
How often do I need to have my test block calibrated?
There is no published specification at this time which mandates block recalibration
If a material is too thin to test alone, can I stack test pieces to increase thickness?
No, stacking one or more additional layers of metallic material together can not make up for an insufficient material thickness. The material flow between the layers will produce inaccurate measurements.
If I see an e error on the test screen of an m200 or m250, what is wrong?
If this is a new unit or you are testing a new test block for the first time, closely examine the test block to see if you have peeled off the thin film protective covering that comes with each test block. If you are testing another piece of metal check the settings of the tester to see if they match with the type of material of the test piece. Next take a test on your test block to see if the readings are OK. If they are not look to see if the ball leaves an indent in the test block surface. If it doesn't the tester may need service. Customer Service is 800-473-7838.
Is there a minimum depth requirement for testing a case hardened specimen on an m200 or m250?
Yes, the depth of the hardness layer on the surface of a heat treated work piece should be equal to or greater than 0.03 in. (0.8 mm). Otherwise, lower hardness values can result due to deformation and vibration of the work piece surface.
Is there a minimum thickness of a test piece when using an m200 or m250 handheld tester?
Yes, the minimum thickness of the work piece under test should be .125 in. (3mm) and it needs to be secured to a table or support.
Is there a surface roughness requirement of a test piece when measuring with an m200 or m250?
Yes, to eliminate measurement error which could result from the roughness of the test surface, the surface should be polished so that a metallic luster appears. The roughness (Ra) of the surface must be limited to less than or equal to 2 microns, which is the equivalent to a smoothness of V6 or above.
Is there a table that lists material types that are suitable for testing on Rockwell scales?
Yes. The table is found in ASTM E-18. Contact ASTM on the WEB at http://www.astm.org. There is also a materials testing Web site at http://www.matweb.com
Is there a weight requirement for a test piece when using an m200 or m250 handheld tester?
Yes, a solid work piece that weighs more than 11 lbs. (5kg) can be tested directly. A work piece that weighs 6 to 11 lbs. (3-5kg) with cantilevers or a thin shell, should be fixed to a bearing or support which weighs over 11lbs. (5kg) to avoid bending, deformation, and displacement during testing. A work piece that weighs less than 4 lbs. (2kg) should be secured to a table or support. The surface between the work piece and the support must be clean, hard, and smooth. Apply Vaseline or yellow grease to the adjoining surfaces of the work piece and support. To secure the work piece, press the work piece firmly on the support, move the work piece back and forth to eliminate any air between the two surfaces.
Is there something wrong with my tester if I am limited to a certain conversion range?
NO, the testers conversion feature is programmed using the data found in Table 1 and Table 2 of ASTM E140 which defines the conversion range. To receive a copy of ASTM E-140 you may contact ASTM on the WEB at http://www.astm.org.
It seems as though the testing is punching through the hardened material on a c scale.
If the objective of the Rockwell test is to measure the hardness of a surface feature such as case hardening, the scale chosen should be based on the thickness of the hardened area. The depth of penetration of a Rockwell C scale hardness reading of C60 is .0032 inches while it's A scale equivalent of HRA 81.2 only reaches a depth of .0015 inches. Choosing a Superficial scale such as 15N would give you an equivalent depth of penetration of .0003 inches.
My 2000 tester forced the indenter through the material into the anvil during the test cycle.
Having the indenter in contact with the material at the start of the test causes the problem. When the test cycle begins, the tester zero's the force on the indenter, (normally zero force). If the test material is in contact with the indenter, the tester zero's out that force and applies the load from that point. This can cause the indenter to drive deeper into or through the material. Raising the indenter up slightly to make sure that the material is not touching the indenter should correct this problem.
My tukon 200 series tester is hung in a test cycle and the start test light remains on.
Someone probably tried to turn the turret after a test was started. Do the following: 1. Turn off the power to the tester. 2. Look at the placement of the diamond inside the black protective cover. It is important to know the distance from the tip of the diamond to the opening in the protective cover for re-installation. 3. Loosen the 8/32 set screw of the black protective cover and remove the cover. 4. With one hand gently pull down on the indenter. 5. With the other hand rotate the turret to the next position and release the indenter. 6. Turn on the AC power and let the tester cycle. 7. Rotate the turret back to the indenter and take a test. If it is OK, re-install the protective cover. 8. Now check the alignment of the protective cover to the end of the indenter using the information that you have obtained from Step 2 above. Problems will occur if the gap from the end of the diamond to the opening in the protective cover is not correct. 9. Try another test to see if the cover is in the correct position. If there are problems you can make minor adjustments to the cover placement and re-test. If you can not make this adjustment remove the cover, call service 800-473-7838 and ask for a Field Service Rep to make a site visit.
My Tukon 2100 tester is not testing correctly.
Stop the test by pressing the RETURN button. The previous message of Waiting to Contact Surface should be replaced by Ready for Ind or Meas. If it isn't, press the STAND BY key, wait for the screen to go blank then press the STAND BY key again. Next, check to see if the indenter is securely seated, the load cell is tight, and on the newer testers, the compliant member directly attached to the load cell should also be tight, then check to see if your specimen is in focus. Start the test, but watch closely to see if the indenter touches the specimen during its initial drop, it shouldn't. After the initial drop the indenter should move slowly to the specimen surface. During this movement the message of Waiting to Contact Surface should be displayed. Once the indenter contacts the surface the message is replaced with Testing MFA. If this is not happening reset the tester as mentioned above, select your lowest powered objective and try a test. If this works OK reset your Parfocality using the procedure in your Users Manual. If service is needed call 800-473-7838.
The display on my 2000 series tester has shut off after thirty minutes.
Your tester has gone into "sleep mode". Press the power button on the user interface and the screen will illuminate. No, there is no way to disable the "sleep mode" feature.

What are Rockwell scale limitations?
At the low hardness end of a ball scale the ball may penetrate too deeply causing the cap to come into contact with a specimen which would damage the cap. In the case of a diamond indenter the sensitivity of the test diminishes as the diamond indenter penetrates further down the conical portion of the diamond. At the high end of the hardness scales, these limits result from the likelihood of fracturing or reducing the life of a diamond indenter such as testing carbide on C scale as opposed to the recommended A scale. A ball indenter is likely to have a flat spot as a result of testing above HRB95.
What are some of the reasons for incorrect hardness readings?
You should check the following:
Replace wrong or damaged penetrators.
Replace worn or damaged Anvil. Replace if necessary.
Remove dirt and oil from under the anvil or penetrator.
Change the rate at which the Major load being applied.
Replace the test block with a new one.
What are the rs-232 settings for my tester?
500 Series To set up 2400 baud, the dip switches on the 500 Series Tester should be set as follows: Dip Switch 1 1 = On (Not Used) =0 2 = On (Not Used) =0 3 = On (Not Used) =0 4 = On (Not Used) =0 5 = On (Not Used) =0 6 = On (Word Length: Off=7 Char, On=8 Char)=0 7 = On (Off= Odd,On=Even)=0 8 = On (Parity: Off = Enable, On = None) =0 Dip Switch 2 (Baud Rate) 1 = On = 0 2 = Off =1 3 = On = 0 4 = Off =1 5 = Off = 1 6 = Off = 1 7 = Off= 1 8 = Off = 1 600 Series The tester is preset at: Baud = 2400 Parity = None Data Bits = 8 Stop Bit = 1 These settings are not adjustable. Series 2000 (Default Settings) Baud = 9600 Parity = None Data Bits = 8 Stop Bit = 1 Consult your Operator's Manual for instructions to change these settings.

What is a knoop indenter, and what is it used for?
The Knoop indenter is an accurately ground diamond forming a rhombic based pyramid. An indent seen perpendicular to the specimen surface is rhombic in outline with diagonals having an approximate ratio of 7 to 1. Because of the Knoop indenter's geometry, indents of accurately measurable lengths are obtained with light loads. The depth of the indent is about 1/30th of the length of the long diagonal. Because of this it is well suited to testing very thin layers of plating case hardened steel, thin metal and foils, thin layers of decarburization and hard, brittle materials. The indenter is very sensitive to the flatness of the specimen's surface, the parallelism of the top and bottom surfaces, and especially to the degree of surface finish.
What is a vickers identer, and what is it used for?
The Vickers indenter ia a diamond ground to the shape of a square based pyramid with an angle of 136 degrees between faces. The depth of the indent it makes is about 1/7 of its diagonal length. The Vickers indenter penetrates about twice as far into the specimen as the Knoop indenter. Therefore, the Vickers test is less sensitive to surface conditions than the Knoop test. Because the indent is influenced less by the flatness and parallelism of the top and bottom specimen surfaces and their finish, it can be used on materials that are not suited for Knoop testing. However, because of the greater depth of the indent, the Vickers test is not as suitable for testing very thin foils and other materials as is the Knoop test. For equal loads, the Vickers indent (because of its shorter length) is more sensitive to errors in measuring the indent.
What is the depth of penetration for regular Rockwell scales?
One Rockwell number represents a penetration of .002mm (0.000080 in.) Therefore, a reading of HRC 60 indicates a penetration from minor to major load of (100 - 60) X 0.002mm = 0.080 mm or 0.0032 in. A reading of HRB 80 indicates a penetration of (130 - 80) X 0.002 mm = 0.100 mm or 0.004in. Note: The numbers 100 and 130 above are the infinite hardness numbers for those scales.
What is the depth of penetration for superficial Rockwell scales?
One Superficial Rockwell number represents a penetration of 0.001 mm or 0.000040 in. Therefore, a reading of 30N80 indicates a penetration from minor to major load of (100 - 80) X 0.001 = 0.020 mm or 0.0008 in. Note: The number 100 used in the calculation is the infinite hardness number used for all Superficial scales.
What is the difference between micro and macro indentation?
Micro indentation uses loads from 10grams to 1000grams. Macro indentation uses loads above 1000 grams.
What is the infinite hardness number for regular Rockwell scales?
When using a diamond penetrator scales the infinite hardness number is 100. When using a ball penetrator scales the infinite hardness number is 130.
What is the infinite hardness number for superficial Rockwell scales?
The infinite hardness number is 100 for all Superficial hardness scales.
What Rockwell scale should I use if I do not know the hardness of a material?
HRA scale, which uses a diamond indenter with a 60kg weight is recommended. A diamond indenter is not likely damaged by penetrating too deeply into soft material, whereas a ball indenter may be flattened or damaged if the material is too hard.
Where can I find test blocks and manuals for my hardness machine?
Please contact Instron Sales at 800-695-4273.
Why are the readings on my test running a few points high?
Make sure you have the proper load selected. If you have too light of a load selected, the indent will be considerably shallow.
Why did my model 2000 stop during a test and prompt an error message?
The problem occurs when the specimen being tested is not properly aligned underneath the indenter. The force is applied to the specimen and the indenter moves down at an angle not perfectly perpendicular. When the error occurs, the operator cannot jog the indenter off the specimen. Perform the following procedure: 1. Scroll through the Menu Field list on the control panel to the CALIBRATE Menu and select Calibrate Depth. 2. Before the status menu states [Calibrating Depth], the operator will be able to press the Jog Up button and allow the force to be removed from the specimen. 3. After the indenter is cleared from the specimen it is recommend that the operator perform another depth calibration (consult your operator's manual).
Why might my display of an indent measurement not show correctly?
Most likely someone has accidentally set the Calibration switch on the rear panel of the Digital Filar box to the Read position. The switch MUST be set to OFF during testing and measuring.
Why might my test sample not generate a hardness value if it the same test was completed earlier?
Check the current weight selection on the tester, is it 500 grams or 1000grams? When you are reading an indent the load weight selector must be set to the same load that was used to create the indent because the digital filar box uses the load as part of the calculation.
Why won't my u-tronics printer print on my digital 500 series tester?
The baud rate of the tester and the printer must be the same, Factory settings are :NO Parity,8 data bits, and Even Parity check. After verifying all switch settings are correct, the cable is connected between the printer and tester, turn on the printer and press the SEL button. You should have both the Red and the Green lights of the printer On. Next, turn on the tester and take a test. The printer MUST be turned ON and Ready prior to turning on the tester. If it still does not print, try running the Self Test feature for the printer by starting with the printer power ON, with the printer in the Offline mode. Offline mode means only the Red light is lit, so if the Green light is ON, press the SEL button to turn it Off. Next, press and hold the LF button,then press the SEL button while still pressing the LF button. The printer should start printing a self test pattern so you can release both buttons once it starts printing. To stop the printing, press the SEL button or you can wait until the printer times out. If self test works OK but the printer does not print under tester control call Service at 800-473-7838.
With a known hardness of a material, what is the thickness required to obtain a Rockwell measurement?
Use Chart 55 the Minimum hardness vs thickness chart. This chart is part of the Wilson Conversion Chart available from Sales at 800-695-4273 or it can be downloaded from Instron's web site at http://instron1.wpenginepowered.com/wa/library/StreamFile.aspx?doc=250 You can also find it on ASTM E-18.

Do I need to calibrate my testing instrument after upgrading to Bluehill Universal?
Based on our software verification and validation testing during product development, we believe that Bluehill Universal upgrades have no effect on the values of transducer calibration and data, nor on subsequent calculations. Please read our Calibration After Bluehill Universal Upgrades Customer Letter at /wp-content/uploads/2024/06/Calibration-after-BHU-upgrades-customer-letter.pdf to find out more information. If your internal standards or compliance to other regulatory bodies outside of ISO or ASTM require you to revalidate your testing instrument after the software change, we recommend a more comprehensive validation. This would include verification of the software calculations critical to your specific application, functionality checking of the software, as well as spot checking transducer readouts against known values. The validation of software calculations is similar to the
IQ/OQ validation that we perform for 21 CFR FDA applications.
If I am testing in an FDA regulated environment, do I need to calibrate my testing instrument after changes to the software?
The FDA has provided guidance on this subject and recommends that whenever software is changed that revalidation is conducted to assess the impact of the change on the entire software system. The guidance goes further to explain the importance of demonstrating that even unchanged portions of the software system have not been adversely affected. For this reason, in an FDA regulated environment, Instron recommends that calibration be conducted as a part of system revalidation after changes to the software. This revalidation process would include a new IQ/OQ/PQ on the system as well. Instron offers a range of support including IQ/OQ services and assistance with your PQ work if desired. Please read Calibration After Software Changes in FDA Regulated Environments Customer Letter to find out more information. /wp-content/uploads/2024/06/Calibration-After-Software-Changes-in-FDA-Regulated-Environments.pdf
