Calibration Preparation Work: Procedure
- Connect the Vehicle Diagnostic Tester.
- Switch the ignition on.
- Tighten three wheel bolt adapters (17 mm) for the wheel bolts on each -VAS6350/1A-.
- Insert the measuring paddle on both -VAS6350/1A- and secure it with the locking nut.
- Place the -VAS6350/1A- onto the wheel bolts on both rear wheels.
- The wheel center mounting rotation center must be in the wheel rotation center.
NOTE: Place the -VAS6350/1A- on the wheels so that the "anti-theft wheel bolts" are not connected with wheel center mounting. - Adjust the measuring paddles using the lock nuts so that they move freely just above the floor.
- The measuring paddles must move easily.
- The measuring paddles must be vertical.
- Position the -VAS6350A- at distance -a- to the rear wheels.
- Dimension -a- = 1, 700 ± 10 mm
- Switch on the -VAS6350/2A- with the ON button.
Display on the -VAS6350/2A-:
- "- - - m"
NOTE: The laser is switched on at same time. - Hold the -VAS6350/2- -2- flush against the catch bracket, as shown, for the distance measurement.
- The -VAS6350/2A- must lie firmly against the catch bracket.
- Make sure the "laser beam" for the distance measurement contacts the lower enlarged part of the measuring paddle -1-.
If that is not the case, correct the measuring paddle height using the locking nuts on the -VAS6350/1A-.
- Briefly press the ON button for distance measurement.
Display on the -VAS6350/2A-:
- "1, 700 m" (specified value: 1700 ± 10 mm).
- Repeat the measurement procedure from the left catch bracket to the measuring paddle on left rear wheel.
- The distance value must be the same on both sides.
- If both measured values are not the same, adjust the -VAS6350A-NOTE: The vehicle in the illustration is only a basic outline.
- Secure the -VAS6350/4- to the -VAS6350A- mount on the rear left.
- When installed correctly, the vehicle electrical system voltage wire must be connected at the bottom left of the calibration device (as seen in direction of travel).
- Dimension -a- = 650 mm (measured from upper edge of calibration device to workshop floor).
- The adjustment dimension is set with the test probe -arrow- on the base of the calibration device on the scale of the steel ruler -1-.
- Left adjustment dimension = 675 mm (read on measuring scale -1-).
- Connect the -VAS6350/4- to the vehicle electrical system voltage.
- Using the bubble level (level indicator) -arrow-, bring the - VAS6350A- into a horizontal position by turning the plastic bases.
- Wear "laser protective eyewear".NOTE: The vehicle in the illustration is only a basic outline.
- Turn on the -VAS6350/3A- on the -VAS6350A-.
- Align the entire -VAS6350A- so that the laser beam shines on the center of the vehicle rear above the VW emblem.
- Check the distance on the left and right sides between the catch brackets of the -VAS6350A- and the measuring paddles -1- on wheel mountings again.
- Specified value: 1700 ± 10 mm
