OBJECTIVE
To provide guidelines for an operation, maintenance & calibration procedure for Multitech Digital Torque Tester.
SCOPE
To establish a procedure for operation, maintenance & calibration procedure for the Multitech Digital Torque Tester.
RESPONSIBILITY
QA Executive.
PROCEDURE
- Switch ON the power supply button on the left side, and display PEAK & PRST.
- Press button E to make the PRST reading Zero.
- Press the button R to make PEAK readings Zero.
- Both readings must be zero before testing torque.
- Press button M to select units. Always select the desired unit by pressing M and don’t press M after the peak is noted.
- Rotate knob adjusts such that the bottle can be held easily. There will be some deflection in the display reading while holding the bottle.
- Press buttons E and R to make PRST and PEAK readings zero.
- Gently rotate the cap anti-clockwise till it becomes loose or just breaks the tamper ring. A peak reading will be displayed. Note this reading, this is removal torque. Check if it is within the standard range.
- For testing the next bottle follow 1 to 8. On completion of testing switch off the power.
- Calibration is done by the following procedure.
- Press menu hold and switch on Torque Tester. It displays TORQUE, CALIBRATION, then press Enter screen displays TORQUE, CALIBRATION, ZERO.
- Then press Enter screen displays TORQUE, LOAD and then press Enter screen displays TORQUE, LOAD, 000.00.
- Hang a load of 1 KG and set torque as follows, press the vertical arrow till you see 000.01, then press the horizontal arrow till you see 000.10.
- Press the vertical arrow till you see 000.11, press the horizontal arrow till you see 001.10, and press the horizontal arrow till you see 11.00.
- Then press Enter screen displays TORQUE, CALIBRATION, OK. Then press Enter screen displays TORQUE, RESET and then press Enter.
- Remove the load of 1 Kg then press E & R to make PRST & PEAK readings zero.
- Now apply standard Torque by hanging 1 Kg standard weight.
- Hanging 1 Kg weight = Torque of 11.0 Kgcm
- Hanging 2 Kg weight = Torque of 22.0 Kgcm
FREQUENCY
As and when required.
