7. ALTIMETER MODE
Use C to enter Altimeter mode.
* Mode prompt “ALTI” is displayed first.
- Altimeter mode indicator is shown.
- The altimeter is of 1 meter (or foot) resolution and with working range from -700 meters (-2296 feet) to 9000
meters (29520 feet).
- Altitude reading in meters or feet selectable.
- Graph showing the changes in altitude is provided.
* Graph will be cleared only after battery replacement or reset.
- Maximum 20 altitude data can be stored.
Reading the altitude graph
The altitude graph shows the relative changes in altitude in the past with the current altitude represented on the
right. Each horizontal point represents 15 minutes while each column represents the relative reading of altitude
in that time.
* It is not possible to get the exact reading from the graph. User can only get the trend of changes from the graph.
To switch between meters and feet
Hold down B until the unit indicator (M or Ft) stops flashing to switch altitude reading between meters and feet.
To store altitude data
Hold down A until “DATA” stops flashing to store the current altitude data.
* “STORED” and data number are shown.
To calibrate altitude reading
1. Hold down D until the current altitude reading starts to flash on the display (Text "HOLD", then in the top line
"CAL"). This indicates the setting screen.
2. Use A (+) and B (-) to change the setting. Holding down either button scrolls the setting at high speed.
3. Press D to exit the setting screen.
* If there is no button operation for 2-3 minutes at setting screen, the display will return to Altimeter mode
automatically.
Display of the accumulated altitude change (ACC) and the maximum measured altitude (MAX)
By pressing the key A in the Altimeter-Mode, the top line in the LCD will show a moving text with the accumulated
altitude changes and the highest measured altitude.
In the calibration mode (see above in "to calibrate altitude reading"), you may reset the two values to zero. While in
the CAL mode, press the key C. The relevant setting will be shown in the top line of the LCD:
MAX: Press key A or B to reset the max value to zero. Then press again key C.
ACC: Press key A or B to reset the accumulated value to zero
The MAX and ACC memory will start to record again as soon as a pressure change is registered.
