Pressure Sensor Calibration
The pressure sensor built into the watch are calibrated at the factory and normally require no further
adjustment. If you notice serious errors in the pressure readings produced by the watch, you can calibrate
the sensor to correct the errors.
Important!
•
Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before
performing the calibration procedure, compare the readings produced by the watch with those of
another reliable and accurate barometer.
To calibrate the pressure sensor
1. Take a reading with another measurement device to determine the
exact current barometric pressure.
2. Use
A
to enter the Barometer Mode (
BARO
), as shown on page
E-31.
3. Pull out the crown. This will cause the current barometric pressure
reading value to fl ash on the digital display.
•
The timekeeping (hour, minute, second) hands will move to 2
o’clock.
4. Rotate the crown to adjust the barometric pressure value.
•
You can also use HS1 high-speed movement (page E-6) to change
this setting.
•
The calibration unit is 1 hPa (0.05 inHg).
•
To return the setting to
OFF
(uncalibrated), press
A
and
C
at the
same time.
5. After you complete calibration, push the crown ba
