8.1.8 Calibrating the HS5E control system

With regular calibration, the calibration functions of the HS5E make it possible
to achieve consistent system behavior by compensating long-term drifts.
You can only carry out the points below in conjunction with a pressure sensor.
We recommend calibrating the HS5E control systemin the following order:
1. Calibration of the pressure transducer (provided by the customer)
2. Calibration of the valve offset
3. Calibration of the swivel angle sensor's offset
4.
Calibration of the swivel angle sensor's gain
5. Calibration of leakage compensation
You can find further information about configuring and activating the calibration
functions in the functional description of the HydraulicDrive firmware (data
sheet 30338).
