TORQUE CALIBRATION

It is necessary to have a torque tester to proceed with the torque calibration operation. Please read the
instructions carefully.
The torque calibration function allows to view the torque value in Nm or lb.in directly on the display.
ATTENTION: The displayed torque level is approximate and it's determined by mathematical calculations.
The smaller the calibration interval the more precise the value on the screen.

IMPORTANT WARNINGS:

− Calibration values will be referred to the parameters of the control unit which are set during
calibration. If you modify speed or type of joint the unit will need to be recalibrated.
− If the screwing cycle during calibration isn't carried out correctly or if you're not sure of the value
it's possible to repeat it. A wrong screwing cycle can affect the precision of the calibration cycle.
− Calibration is carried out for two torque levels optionally chosen. The minimum calibration interval
is 2% (example: if I have to work at 30%, I can calibrate at 29% and 31%) but we recommend a
minimum of 10% interval.
−
Torque percentages which are higher than the maximum one set during the calibration will be
analyzed and displayed anyway. They will be theorized by the system and they won't be based on
effective data, therefore the analysis won't be precise.
− During the calibration it's impossible to go back to the previous screen. Press ESC to stop
calibration and then repeat the cycle.

CALIBRATION PROCESS:

1. Select Calibration at point 17 of the menu and press OK.
2. The following screen will appear on the display:

3. Choose if you want to set calibration ON or OFF, then press OK to confirm or ESC to exit. If you
choose OFF calibration will be interrupted and no torque value will be displayed. If you choose ON
calibration will continue and the following screen will be displayed:
4. Set the first torque level percentage by pressing
5. Complete a fastening cycle.
6. If you're sure of the torque level displayed on your torque tester press OK, then set the displayed
value and press OK again to save. Otherwise press ESC and start again.
7. The following screen will be displayed. Set the percentage of the second torque by pressing
and press OK.

8. Repeat the procedures described on points 4 and 5.
9. When calibration ends, "Setting end" will be displayed. You will hear two beep sounds, too.
