SCOPE:
To establish a procedure for an operation, maintenance & calibration procedure for Multitech Digital Torque Tester.

RESPONSIBILITY: 
QA Executive.


PROCEDURE:
  1. Switch ON power supply button on the left side, display PEAK & PRST.

  3. Press the button R for making PEAK readings Zero.
  4. Both readings must be zero before testing torque.
  5. Press button M for selecting units. Always select desired unit by pressing M and don’t press M after peak is noted.
  6. Rotate knob adjust such that bottle can be held easily. There will be some deflection in display reading while holding bottle.
  7. Press buttons E and R for making PRST and PEAK readings zero.
  8. Gently rotate cap anti-clockwise till it becomes loose or just breaking tamper ring. A peak reading will display. Note this reading, this is removal torque. Check if it is within standard range.
  9. For testing next bottle follow 1 to 8. On completion of testing switch off the power.
  10. Calibration is done by the following procedure.
  11. Press menu hold and switch on Torque Tester. It displays TORQUE, CALIBRATION, then press Enter screen displays TORQUE, CALIBRATION, ZERO.
