Good morning everyone, yesterday I changed my tsdz2 to v20.1c.3 LCD3, after making the changes in battery levels, etc. The screen displays "error 02" this is an assist torque error. I have read in the manual but I can't understand how to calibrate the torque assist. Can you help me?
thank you
These are the manuals (not fully updated):

The menu items for calibration:
3.0 - Torque sensor calibration
Enabled / Disabled.
Enable only after having entered the actual values of “Pedal torque ADC offset” and “Pedal torque ADC max”, obtained from the calibration.
Enabling without having entered the correct values can lead to unpredictable operations.
Calibration procedure: display in the "Technical Data" menu, the item (11.2) - "Torque sensor ADC value", enter the ADC value of the torque sensor without any push on the pedals in "Pedal torque ADC offset" (10.10). Enter the ADC value of the torque sensor with the maximum thrust applied to the pedal (cyclist standing on the right pedal in horizontal position) in "Pedal torque ADC max" (10.11).
Torque sensor calibration is required if the working range is limited, “Pedal torque ADC max” - “Pedal torque ADC offset” < 140.
Caution. The ADC values of the torque sensor over time may change, check periodically.
10.10 - Pedal torque ADC offset (no weight)
ADC value of the torque sensor without any push on the pedals.
It is obtained from the calibration procedure to be carried out on the display.
When you need to increase the sensitivity at the start, for example with a arm-bike, subtract a number from 1 to 10 from the value obtained.
Caution. Decreasing the offset value too much can cause an unwanted start and / or a delayed motor stop.
10.11 - Pedal torque ADC max (max weight)
ADC value of the torque sensor with the maximum thrust applied to the pedal (cyclist standing, on the right pedal in horizontal position).
It is obtained from the calibration procedure to be carried out on the display.
This parameter is used to amplify the range of use of the torque sensor when it is too limited.
Check that the assistance is well distributed over all levels and in all modes, if necessary correct the value obtained in plus or minus. Lower value = higher amplification.
