SCALE
REF.MAGN
Adjusting procedure:
If the I/O PCB has an R140 (SCALE REF. MAGN) potentiometer
(refer to composition diagram 102 D 863 HP011)
Connect the voltmeter to the following test points (TP):
TP1

TP12 + (COS)
1) Turn the probe until the voltmeter shows a maximum voltage value. Adjust potentiom-
eter R140 until a voltage of +5.5V (--5.5V) appears.
2) Turn the probe slowly in its holding ring until the actual heading display
(PILOTSTAR D) is identical to that of the magnetic compass heading.
(In this setting, check the sense of rotation of the phases):
-- if the probe is turned in the direction of higher magnetic compass
values, then the actual heading display must be correspondingly larger.
If the sense of rotation is incorrect, then probe connections S1 and S3
must be swapped.)
The probe is screwed in at this location.
