Operation Guide 3070

Barometer and Thermometer Precautions

The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications.

Sudden temperature changes can affect pressure sensor readings.

Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature 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 and temperature 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.

Incorrectly calibrating the temperature sensor can result in incorrect readings. Carefully read the following before doing anything.

Compare the readings produced by the watch with those of another reliable and accurate thermometer.

If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.

1.Press B to enter the Barometer/ Thermometer Mode.

2.In the Barometer/Thermometer Mode, hold down Efor about two seconds until either OFF or the reference temperature value starts to flash. This is the setting screen.

If you want to calibrate the barometric pressure sensor, press D to move the flashing to the middle display area. This is the pressure sensor calibration screen.

At this time, OFF or the barometric pressure value should be flashing on the display.

3.Use A (+) and C (–) to set the calibration value in the units shown below.

Temperature

0.1°C (0.2°F)

Barometric Pressure

1 hPa (0.05 inHg)

Pressing A and C at the same time returns to the factory calibration (OFF).

4.Press E to return to the Barometer/ Thermometer Mode screen.
