Calibrating/Adjusting Procedure with or Without a Previous Axle Alignment

• Select the front camera calibration procedure in the alignment computer.
• Make sure the calibration board is positioned in the center and is locked in place.
  • Dimension -a- = dimension -b-.

• Position the -VAS6430/1A- at a distance of -A- 150 cm ± 2.5 cm from the center of the wheel hub on the front wheels to the beam on the -VAS6430/1A- as shown in the illustration.
  • The -VAS6430/1A- must not be moved on the calibration beam.

• Mount the front wheel measuring sensors -1- to the - VAS6430/1A-.
  • The alignment stand must be in the lowest level position for the next step.

• Enter the height value -A- between the -VAS6430/1A- contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.
  • Height of the calibration board: 1400 mm + height value -A-.

• Loosen the bolt -arrow- and place the measuring bar -1-on the floor.

• Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.

If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.

• If in later procedures the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.

  • Level the bubble level -A- using the adjusting screw -1-.

The bubble level adjustment -A- serves to balance the ground conditions.

• Move the -VAS6430/1A- sideways -arrow B- until the display on the alignment computer is within the tolerance range.

• Secure the -VAS6430/1A- by tightening the bolts -2- and -3- slightly. (This prevents the -VAS6430/1A- from rolling away).

• Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.

• Level the bubble level -A- using the adjusting screw -1-.
• Balance the bubble level -B- using the adjusting screw -2-.
  • Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked again.
