4.11 Adjusting the Flux--gate Compass Sonde (with SIN/COS Output)
Notes for a flux--gate compass sonde with a serial data transmission:
For this compass type, no adjustment is required.
The ship--specific parameter MAG TYP (see Chapter 4.5.1 and Annex -- 4)
has to be adjusted for the value
2 .
Measuring equipment:
A commercial voltmeter is to be made available (PC range).
Pre--condition:
Check the significance (1) of the ship--specific parameter MAG TYP (see Chapter
4.5.1 and Annex -- 4).
Adjust the COMPASS Type MAG via the operator unit.
Make shure that the ”Variation” parameter is 0

.
Measuring / Adjustment:
(refer to summary diagram 102 D 863 HP011)
Connect the voltmeter to the following test points (TP):
TP1

TP12 -- (COS)
Turn the flux gate until the heading indication in the LCD display indicates 0

.
The voltmeter have to indicate a voltage of -- 4,9 ..... --5,9V.
If the value is >--5,9V, the value has to be reduced via an additional input resistor
(terminal B26.5 and B26.3).
Example of calculation :
For a reduction by the factor 2, a resistor of 100 k

is to be built--in.
Alternative measurement
Connect the voltmeter to the following test points (TP):
TP1

TP11 -- (SIN)
Turn the flux gate until the heading indication in the LCD display panel is 90

.
The voltmeter have to indicate a voltage of --4,9 .... --5,9V.
