Run a test
Ensure that the following conditions are met before a test is run:
• The LOAD channel is calibrated.
• The STRAIN channel is calibrated if you are using an extensometer.
• You have reviewed the manuals for the controlling software and are familiar with the on-line help
system that accompanies the software.
• Know the specific procedures to set up and run a test.
• The load transducer, grips and fixtures are appropriate for your test.
Following is the recommended procedure to run a test on a specimen:
1. If the system is not currently turned on, complete “Start the system” on page 37.
2. Verify that the setup and test parameters are reasonable and correct for your test.
3. Ensure that the displays on the user control panel illuminate.
4. Check that the frame is enabled.
5. Start the HPS. The FRAME READY indicator will illuminate. Immediately check the position of the
piston within the hydraulic cylinder; the piston should be positioned so that it is neither fully retracted
nor fully extended. If the piston is in either of these conditions, the servo loop control could build up
enough error to shut down the HPS. Use the jog controls to move the piston if necessary - typically a
separation of 6 mm (0.25 in) is sufficient.
6. Determine the required test opening and stroke needed to complete the desired test. Be sure to take
into consideration the effective length of the fixtures that will be used, the length or height of the
specimen, and the expected change in length or height that the specimen will undergo during the
test.
Always wear appropriate personal protective equipment when preparing, operating and
maintaining this equipment. Personal protective equipment should include, but is not
limited to, eye protection and head protection. Other types of personal protective
equipment may also be needed. You must perform your own risk assessment and take
appropriate measures to protect yourself from harm.
This information is NOT test specific, it is only intended to assist you in the general aspects of running a
test. If you are testing to a specific standard or society specification (ASTM, ISO, EN, BS, etc.), those
specifications should be obeyed with regard to number of tests run, specimen specifications, fixturing,
inserting specimens and all other aspects of materials testing.
This document presumes that customer training (by Instron Service Engineer) has been completed and
that at least one procedure has been created in the controlling software.
Refer to the supplied software manual for specific information about the controlling software. The
following is only a general description of the necessary steps to run a test.
