ALTITUDE CALIBRATION
If the altitude on the display is different from the actual
current altitude, the unit can be manually calibrated to
reflect the true altitude level.
To calibrate the altitude:
1. In Normal Altitude Display.
2. Press and hold [ALT] and [TIME] simultaneously for
about 2 seconds. The CAL Hx indicator shows on the
display and the current altitude digits start flashing.
3. Press [+] or [-] to adjust the altitude reading by 1
meter. For rapid acceleration of measurement
adjustments, press and hold.
4. Press [ALT] to confirm and return to the Altitude
Display.
Example:
Point C: A point where the altitude, as indicated by a
marking stone or post, is 1500m. At this point
set the current altitude to 1500m.
NOTE The unit will return to Normal Altimeter Display if
no buttons are pressed for one-minute during the
calibration sequence.
UNITS OF MEASUREMENT FOR ALTITUDE
Altitude measurements can be displayed in feet (ft) or
meters (m).
To change the altitude units of measure:
1. In Normal Altitude Display.
2. Simultaneously, press and hold the [+] and [-] to
select between meters or feet.
ABOUT THE ALTITUDE CHANGE GRAPH
In Normal Altitude Display, the EB833 graphically display
altitude levels at 2-hour time intervals for the past 12
hours. Each vertical bar on the altitude graph represents
a 2-hour time period. Each horizontal line represents
pressure changes equal to + /- 200m.
The Altitude Change Graph is viewed in all the Altimeter
Mode displays.
