16. Calibration
The indicator of temperature and air humidity in the display of the base station can be
calibrated. That means the deviations from a reference value (such as from a high-
quality measurement device) can be corrected by adding to or subtracting from a value
for the indicator.
Please observe that:
The indicator in the display of the external sensor cannot be calibrated.
When you have calibrated the indicator in the display of the base station, the
display of the external sensor shows a different value.
a) Calibration of the temperature
• Press the "CHANNEL/+" button (17) briefly and repeatedly, until the arrow symbol (5)
appears at the desired channel (if the external sensors are registered with channel
4 - 8, choose the corresponding channel number).
• Press and hold simultaneously both of the "ALARM/ADJUST" (16) and
"CHANNEL/+" (17) buttons for 5 seconds.
As a result, the temperature value begins to flash.
• Change the temperature value with the "MIN/MAX/-" (15) or. "CHANNEL/+" (17) but-
ton. Press and hold the corresponding button for a longer period of time for a quick
adjustment.
• If the temperature value needs to be reset back to the non-calibrated output value,
press briefly the "ALARM/ADJUST" button (16).
• To save the calibrated value and leave the set-up mode, press and hold the "ALARM/
ADJUST" button (16) for 3 seconds.
The set-up mode will be automatically ended when you do not press any button for a
few seconds. In that case the base station uses the previous settings.
