required, do the following:
11.4.1
Temperature Sensor Calibration
•
Use an accurate thermometer as a reference.
•
Place the thermometer near the temperature sensor.
•
Make sure that the inside temperature is stable.
•
Calibrate the temperature sensor immediately after reading.
11.4.2
Calibration Procedure
1. Press
SELECT
and the “up” arrow keys simultaneously and hold them together for about two
seconds. The display alternates between the sensor number and the temperature measured.
2. Use the arrow key to change the temperature.
3. Press
SELECT
to move through the sensors and the arrows to change temperatures.
NOTE:
Calibration of humidity sensor is done exactly the same way; the only difference is that instead
of measuring temperature, the humidity is measured by an external humidity sensor.
