Calibrating Barometric
Pressure Readings
The watch's pressure sensor is adjusted at the
factory and normally does not require
calibration. However, you can calibrate the
displayed value if you notice major errors in
readings.
Important!
The watch will not be able to produce
●
correct barometric pressure readings if
you make a mistake during the
calibration procedure. Check to make
sure that the value you use for
calibration produces correct pressure
readings.

Calibrating Temperature
Readings
The watch's temperature sensor is adjusted at
the factory and normally does not require
calibration. However, you can calibrate the
displayed value if you notice major errors in
readings.
Important!
Check to make sure that the value you
●
use for calibration produces correct
temperature readings.
Before calibrating the temperature
●
reading, remove the watch from your
wrist and leave it in the area where you
plan to measure temperature for about
20 or 30 minutes to allow the case
temperature to become the same as
the air temperature.
