Compass calibration

If the Module was exposed to a strong magnetic field or was not

in use for a long time, the compass accuracy may diminish.

To bring the compass into working condition:

 Select Cd 17 in the Setup mode

 Keeping the unit horizontally, perform one full rotation

around vertical axis within half a minute and then one full

rotation around vertical axis with device upside down

during half a minute.

 If one rotation does not restore calibration – perform two

rotations.

The normal compass functioning will be restored.

Depending on the version of the on-board software, during

calibration LCD will show either time countdown in seconds

from 59 to 1 or flashing word CAL.

To ensure azimuth measurement accuracy calibrate compass

after changing the battery.

Interface format

The unit can output measurement data via RS-232 port in either a

proprietary protocol or in the format accepted by PLGF/DALGR.

The selected format will be indicated on the LCD with display

names

PLGr or -PC-.

To select the required data transfer format:

 Select PLGr (-PC-) in the Setup mode
