Calibrate depth
The depth indication also responds to air pressure/atmospheric pressure. Therefore, it is possible
that the depth display does not show 00.0 when switched on. But for instance on 00.2. This can be
reset to 00.0 in this menu.
Raw sensor values and IMU sensor values
This is digital output from the MEMS sensor. This is only intended for service point maintenance
applications.
Set declination
Magnetic north and true north (geographic poles) are not the same. The value varies per location
and can be positive or negative. Also, this value varies slowly over time.
For example in 2021:
- the Nethe 1.88//G3.1//United K0.3//B1.92//2.3
This value needs to be adjusted according to the location of the dive. There are several
websites where these values can be found. (

If the declination value is not entered or not entered correctly, the north will differ from
the actual north.
