Measure Absolute Angle At Front And Rear Propeller Shafts - AR41.10-P-0085-02LW

Model 205, 213, 238, 253 

Notes on measuring the drive shaft articulator angle

AH41.10-P-0002-01LF

Measurement of angle 2 at front half of propeller shaft 

All four angles should be measured in succession without interruption. An angle that has already been measured can be measured a second time if required. To do so, with the Measurement menu displayed, press the STEP button repeatedly until the display indicates Ready to measure the relevant angle.

1. Clean contact surface of test adapter (3) of sensor (020a) at front half of propeller shaft (1).
2. Position test adapter (3) vertically from below onto front half of propeller shaft (1) and align.
3. Place sensor (020a) from above onto test adapter (3).

   When each measurement is taken, the side of the sensor (020a) at which the spiral cable (020b) is connected must point in the direction of travel. False measurements can occur otherwise.

   The test adapter (3) must be aligned vertically with the spirit level. If the sensor (020a) is not positioned vertically from below, the fault message "Y-positional error - sensor??" appears. The measured angle cannot be saved.

   The value measured is shown on the display.

4. Press SAVE button. The values are saved.

   Measurement of angle 3 at rear half of propeller shaft 

6. Clean contact surface of sensor (020a) at rear half of propeller shaft (2).
7. Position sensor (020a) vertically from below on rear half of propeller shaft (2) and press on firmly.

   When each measurement is taken, the side of the sensor (020a) at which the spiral cable (020b) is connected must point in the direction of travel. False measurements can occur otherwise.

   The test adapter (3) must be aligned vertically with the spirit level. If the sensor (020a) is not positioned vertically from below, the fault message "Y-positional error - sensor??" appears. The measured angle cannot be saved.
