ALTIMETER ALTIMETER
Because the ALTIMETER system in the Axis relies on barometric pressure for its measurements, it is
critical that you regularly calibrate the unit to a known altitude. For maximum accuracy, daily calibration
is a must. If you are using the unit during times of changeable weather, the unit may need to be
calibrated more often. Generally, the small pressure changes experienced during a day of use will have
only a minor effect on the accuracy of the unit, however, the arrival or departure of a weather front can
change the current weather display by several hundred feet or more.
The ALTIMETER has one display screen. When you enter the altimeter the TOP LINE will scroll,
showing you your MAXIMUM AND ACCUMULATED altitude since the last time they were reset.
After the scroll has completed, the TOP LINE shows you a graphic indication of altitude changes over
time. The CENTER LINE of the display shows your current elevation and the BOTTOM LINE shows
the TIME OF DAY. SET ALTIMETER (continued)
5. Set the CURRENT ALTITUDE and advance to the ALTITUDE
MEMORY displays using the S3 key.
6. There are two altitude memory displays showing the Maximum
Altitude and Accumulated Ascent since the last time the memory
was cleared. Clear each memory using the
S1 or S2 key and
advance from the MAXIMUM to the ACCUMULATED memories
using the
S3 key.
7. Exit the ALTIMETER CALIBRATION sequence using a QUICK
PRESS of the S4 key.
