Cell zero value
Zero factory value for the torque transducer; if the current zero value
performed every time the wrench is switched on varies by more than 2% of
this value, an error message is shown on the wrench display.
Cell zero date
Last calibration date of the smartHEAD.
Gyroscope present
This flag is automatically enabled if the current smartHEAD plugged into the
controller has the gyroscope installed. If yes, the next two fields are also

value performed every time the wrench is switched on varies by more than
0.5% of this value, an error message is shown on the wrench display.
Gyroscope zero time
Last calibration date of the gyroscope.
smartHEAD angle

When a wrench extension is used, its angle correction coefficient must be
calculate and added to the end fitting tool or Pset parameters.
Overloaded, value and
