Electronic Compass
An electronic compass provides improved situational awareness by
displaying N, NE, E, SE, S, SW, W or NW depending on which way the
camera is pointing.*
*Mi-TIC S only
The compass will work within 45 degrees from vertical in both axes.
When the camera is tilted past 45degrees, the tilt symbol
is displayed instead of
the heading.
The Cameras compass must be calibrated with each battery, to compensate for any
magnetic offsets.
When a compass requires calibration the calibrate symbol
is displayed.
The camera must then be rotated through all axes, as shown below.
When the calibration has been successful, the heading will be displayed in yellow for
10 seconds, and then turn back to the standard green heading.
These settings will be saved for future use, therefore when the camera is restarted the
compass will be displayed immediately.
If during use the compass is rotated through all the axes and a completed calibration
is performed, the compass will save the new calibration and turn yellow for 10 seconds.
If during use, the compass appears inaccurate, this recalibration routine can be
performed to ensure accuracy.
Warning:
The accuracy of the magnetic compass will depend on correct calibration and isolation
from external magnetic interference. Interference can be caused by, but not limited
to, soft iron structures and electrical equipment. The compass should be used as an
aid only and not relied on as a primary means of navigation.
This function is part of the TI BASIC PLUS operational format (see 3.9)
