Make a measuring run at a cruising
speed, which remains as constant as
possible.
Check that the calibration factor is
C=1.00 (as supplied) at the beginning
of the measuring run, and that the trip
distance counter is set to zero.
The following example refers to a measuring run in water without a cur-
rent with a measuring length of 2 nautical miles (nm).
Approach starting point A of the measuring length.
Set the trip distance counter to zero (see page 28) when passing star-
ting point A.
Follow the measuring length on a straight line and note the indicated va-
lue (1.74 nm in this example) when passing end point B.
Calculate the calibration factor C with the following formula:
Effectively covered distance (A-B)
2.00 nm
C = --------------------------------------------------- = -------------- = 1.15
Indication of the display (A-B)
1.74 nm
Enter the calculated calibration factor C (1.15 in the example) as follows:
Keep pushbutton pressed and switch the indicating unit power supply
on. The display shows „CAL“.
Release the pushbutton. The current calibration factor is displayed (as
supplied: 1.00):
