Fields to Display, bit mask of 5 bits (entered in decimal). 31=all active.
Sum up the values, Azimuth=1, Pitch=2, Roll=4,Temp=8,depth=16.
<Esc> Q
Enter Declination angle to create offset for compass Azimuth. Value is
10x degrees. Example: -103=-10.3 degrees, 152=15.2 degrees.
<Esc> C
Calibrate the compass in the platform. Level the platform and prepare
to rotate it very slowly. When the output reports “XxYy” it is finding
new calibration data, keep rotation until you see only “.”’s output. You
MUST keep the platform level while you rotate. Validate the Roll and
Pitch angles are < 1 degree in the output string R0.x, P0.x before starting
<Esc> Z
Rotate your platform 90 degrees on it’s side. This will place the Z axis in
the same “earths” magnetic field the “C” calibration saw for the x,y
sensors. Perform once complete and slow rotation.

<Esc> A
Moving average filter on roll, pitch and heading. Enter the number of
samples to include in the average. This combined with output rate will
determine the period of the filter. Example: averaging = 5 output rate =
10 is half second period

Calibrate Temperature, offset in O.1C, example <esc>+-131<enter>
will subtract 13.1 from the reported temperature. Temperature is a crude
sensor and should not be used if accuracy is required, it is a good relative
measure of changes in the electronics rack.
<Esc> U
Calibrate Raw Magnetic output, milliguass of horiz field requires new
calibration. The value you enter is the local horizontal field strength of
the earth’s magnetic field. After you enter this and do a calibration the
compass will output 3 axis magnetic sensor values in milliguass. The
local H field strength can be estimated using the NOAA world magnetic
model for you local area.
<Esc> D
Digital Filter Value for AD conversion, higher=longer filter time. The
default value is 3, using a higher value will add lag to the measurements
but filter noise.

Format 8 requires firmware version 1.4.
