the vehicle as a handheld compass.
How do I read the display?
The compass displays direction in 2 different formats (1) cardinal points (N, NNE,
NE, E, etc.) and (2) numeric digits (325°,
330°, etc.) The 16 cardinal points of a
compass (N, NNE, NE, ENE, E, ESE, SE,
SSE, S, SSW, SW, WSW, W, WNW, NW,
NNW) give you a general sense of direction. The numeric digits show your exact
direction down to the nearest 1 degree.
What is calibration and why is it
necessary?
Calibration is the process whereby the
compass separates the earth’s magnetic
eld from externally generated magnetic
elds such as those generated by a vehicle’s steel body or electronics. Without
calibration, the compass thinks the entire
magnetic eld it is reading is from the
earth and consequently
displays inac-
curate compass readings.
When do I need to calibrate the compass?
The compass needs to be calibrated when
used for the rst time, when used in
an environment with a different magnetic
eld or when the batteries are removed or
replaced. Using the compass in a different
environment includes moving it to a new
