Compass calibration
Full calibration process consists of three procedures,
which shall be conducted in the following sequence:
1. Elevation
correction
2. Hard
calibration
3. Soft
Calibration
However all three procedures shall be done only at
initial installation and integration of the device, or if
some large hardware elements permanently attached
to the device were changed. For example bracket
made of magnetic metal was replaced or modified. If
calibration is performed only to improve accuracy of
readings, only the Elevation correction and Soft
calibration shall be performed.
Correction of the vertical angle (Elevation correction)
- Turn on the LRF.
- In the LRF menu, select «Std», then «E». Press
ACTION.
- Select «SET», then «CAL». Press ACTION.
- Position LRF strictly flat. Select «corr» and press
ACTION.
If device is not positioned perfectly level during
calibration, this process will introduce permanent
