Program Your Torque Tester and Get Two Peak Values?

If you would like to program your torque tester and be able to get two distinctive peak torque values (thread break torque and Tamper Evident Band (TEB) break torque), the ST-120S or the ST-S3 torque testers can be programmed as follows:

  1. Associate a product name with the test recipe.
  2. Set the test mode to “Release”.
  3. Set the cycle count to 2. In the first cycle, the machine will measure the peak of the thread break. In the second cycle, the machine will measure the peak of the tamper-evident band (TEB) break.
  4. On the second “Test Setting” screen, set the “rotation speed” to 20rpm, the “release torque limit” to 20lbfin, the “starting torque” to 10%, the “torque ramp” to 30s, and the “method” to the rotation.
  5. Set the “rotation limit” to 250 degrees. Starting with a tight cap (applied torque >10lbfin), the thread break torque can be measured under 30 degrees. However, there is a single rotation limit setting, so the torque limit should be set reasonably close to the peak of the TEB break torque. After a few experimental cycles, the desired rotation limit is 200-250 degrees.
  6. To give the operator time for manually documenting the thread break (1st cycle), go in the Setup/Timers submenu and set the “New Cycle” delay to 5s.
  7. Alternatively, when a computer is capturing data from the machine the new cycle delay can be set to 00:00:50 (500ms).
