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.

( 2 HOURS PER COLUMN )

The Altitude Change Graph is viewed in all the Altimeter Mode displays.
