Calibration
The actuator is delivered to you calibrated. If you detect a deviation using a suitable checking device (electronic spring balance),
please calibrate the actuator as follows:
1. Start the drive
2. Select LBS (pounds) - the calibration must be carried out in LBS and not in kilograms!
3. Press and hold the "SPEED" button. Then press the "KNOT" button to start calibration mode
4. Install the Tension Calibrator and press the Pull/Release button
5. Use the - and + buttons to change the weight on the display according to the weight shown on the Tension Calibrator.
6. If both weights match, press the "TEST" button to save the weight and start a restart.
7. Remove the tension calibrator immediately

It is recommended to switch off the drive briefly after calibration. Additional
information: The digital display may "jump" after the string has been pulled. This
does not mean that the drive unit needs to be calibrated. This "jumping" may be
due to the mechanical performance of the drive.
