7. Set the percentage of the second torque to 25% by pressing and press OK.
(25% is just an example).
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.
Now you are ready to work and see the correct torque on the display.
WARNING:
- Calibration values will be referred to the parameters of the control unit which are set during
calibration, i.e. if you modify speed or torque, the unit will need to be recalibrated. During
calibration when a screwing is not carried out correctly or if for any reasons you’re not sure of the
torque value it is possible to repeat it. A wrong screwing can affect the precision of the calibration.
- Calibration is carried out for two torque levels optionally chosen. The minimum calibration interval
is 5% (example: if I have to work at 50%, I can calibrate at 45% and 55%). In this case, if for any
reasons I need to work at torque percentages which are lower or higher than the min-max ones set
during the calibration, they will be analyzed and displayed anyway but since they won’t be based on
effective data the torque value displayed may be not accurate.
- During calibration it is not possible to go back to the previous screen. Press ESC to stop calibration
and then repeat the screwing cycles.
USE OF T&A (Torque & Angle)
Choose the T & A mode (see point 29: Modify function on the program menu)
It is possible to set 6 different modes:
TORQUE (Torque): It’s the most common use mode. The control unit shows the tightening torque and
the torque starting from a certain torque percentage (threshold torque, see point 30). If the final torque
and angle values are within the preset minimum and maximum values, the screw is correctly tightened.
If the torque and/or angle are outside the preset values, the screw will be considered as incorrectly
tightened. In this case the red led will light up and the message “Error Max (Min) Angle” or “Error Max
(Min) Torque” will be displayed.
