2.3 How to Adjust the Analog Indicator
If it is necessary to adjust the offset or gain of the analog indicator or analog output,
output dummy speed from the demo mode then adjust the applicable potentiometer
on the MAIN board in the DS-610.
How to adjust the analog indicator
1. Set 0 kn for test speed in the demo mode, then adjust the offset of the analog in-
dicator.
2. Set 15 kn or 20 kn for test speed in the demo mode, then adjust the gain of the
analog indicator.
Note: Do the test for the gain adjustment with the ship’s cruising speed.
