Information 

The POWYS Tester  instructions take precedence since the description may be different with later Tester releases.

The procedure described here has been structured in general terms. Different text or additional information may appear on the POWYS Tester. 

Information 

The required height of the calibration board and the distance of the calibration board from the vehicle will not be displayed on the wheel alignment computer. These values are stored under Front camera calibration  in the Tester.

Information 

Set vehicles with air suspension to normal level (medium height). 

1. Only for vehicles with air suspension
   1. 1.1  Set the chassis height in the display and operator control unit to Normal level (MEDIUM HEIGHT). 
   2. 1.2  Set the chassis in the front display and operator control unit to Car jack mode. 
      1. 1.2.1  Deactivating the levelling system: Select CAR > CONTROL > Vehicle > Chassis > Car jack mode  in the central display.
2. Since the bonnet must be closed in order to calibrate the front camera, connect a battery charger directly to the battery.
   1. 2.1  Remove battery terminal cover.
