Manual zero adjustment
The zero point of the torque output can be adjusted manually. For this purpose both push buttons T1 and T2 are
activated simultaneously for 2 seconds. The LED L1 is blinking four times.
Pressing the push button T1 increases the voltage, pressing the push button T2 decreases the voltage. The
modifications are accelerated if the corresponding push button is pressed permanently. Each amendment is
confirmed by short blinking of the LED L2.
Having performed the adjusting the new values are stored lastingly by pressing both push buttons again for
2 seconds. The LED L1 is illuminated once and signalizes the return to the measuring mode.
The manual zero adjustment can only be performed if the measuring shaft is switched on
for more than 15 seconds and the signal has levelled off.

Sensor test
During the first 15 seconds after powering up the torque sensor can be inspected for operativeness. If the push
button T2 is pressed for 2 seconds the torque voltage output will be increased by approx. 4 Volt for the period of
2 seconds.
The sensor test can only be performed during the first 15 seconds after switching on.
