Setup
-
Hold (S2) for 1 second, “
SET
” will display on Field 1 and a zero
value will begin to flash on Field 2
- Press (S3) or (S4) to select a non-flashing pressure difference
(the previous pressure difference record) to resume the previous
difference measurement or select the flashing zero to start a new
difference measurement. For a new difference measurement the
time will start running automatically.
- Press (S1) to accept the setting
- Press (S4) to stop or resume the measurement
Note
-
Every time this mode is entered, the reading will start with
flashing zero.
-

functioning
- When Altimeter Use is selected, all information will not change in
this mode.
- The watch will return to Time Main Mode after 12 hours.

- Press (S3) or (S4) to view records
Note
- The latest 6 records are taken in 1-hour intervals. Other records
are taken in 6-hour intervals
- Barometer trend indicator only appears in this mode when
Altimeter Use is selected.
- The watch will return to main mode after 10 minute.
Calibration of Absolute Pressure
- User can calibrate the absolute atmosphere pressure.
Adjust
- In the Barometer Main Mode, hold (S2) for 1 second, the
absolute atmosphere pressure value will begin to flash on field 2
- Press (S3) or (S4) to set,
- Press (S1) to accept the setting
Important notes
- The absolute pressure is calibrated by factory, it is not
recommended for the user to set the value in daily use.
- When there is a physical characteristic shift of sensor due to
aging, or when the watch has been left unused for more than one
year, calibrating the absolute pressure is recommended.
- To find out an accurate pressure value, use a professional
barometer to calibrate the absolute pressure.
- User can also adjust the watch at seaside after getting an
accurate sea level value from local weather observatory.
Remarks
- Pressure and temperature changes are measured in intervals of
10 seconds.
- Barometric values are measured at 1-hour intervals to estimate
the barometric trend.
- Temperature range: -10 °
