1. At the SDAC 1 (1WV1) connector: On the digital multimeter display:
-
measure the voltage between pin - make sure that the voltage is AB/11D and AB/11C. 2,335V +/-0,025V.
-
measure the voltage between pin - make sure that the voltage is AE/11F and AE/11E. 2,600V +/-0,025V.
-
measure the voltage between pin - make sure that the voltage is AE/11H and AE/11G. 2,600V +/-0,025V.
NOTE : If the voltage values are not correct, possibly the accelerometer or
____ the aircraft is not in horizontal position. To adjust the accelerometer in the correct position, washers can be removed or be added. ________
