5) Reset: you can select which parameter resets when you press RESET (see point 4: Keyboard
commands). If PRG, the Reset refers to the program that is being carried out. If SEQ, the Reset refers to the
whole sequence (only if sequence is enabled).

6) Set time & date: to set time and date on the control unit.
7) Cycles - Total number of cycles: It shows the number of tightened and loosened screws. This number
can’t be modified.
TORQUE CALIBRATION
Please read the instructions carefully and equip a torque tester to proceed.
The torque calibration function allows to view the torque value in Nm or in.lbs 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 5% (example: if I have to work at 30%, I can calibrate at 25% and 35%) 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:
