Azimuth and inclination measurement
The Laser Locator has a digital
compass that works similarly to
a magnetic compass. Metal
objects and magnetic fields can
cause errors in directional
readings. Nonmagnetic metals
and alloys do not affect the
compass readings.
Countermeasures:
Calibrate the compass (see
pages 30–32) after every battery
change.
Observe the minimum safe
distances shown opposite when
making azimuth measurements
or calibrating the compass:
