Calibrate a sensor if the displayed temperature or humidity on the sensor deviates from
the actual value. For example, if the return air temperature measured by other
temperature detection devices at the return air detection point is 20° C while the value
measured by the sensor is 22° C, the sensor has an error of 2° C, and the calibration value
should be set to –2° C.
To calibrate a sensor, log in as the Admin or Engineer user.
You can calibrate for touching point deviation on the touchscreen.
You can calibrate the screen by tapping the screen on the Screen Calib page or by DIP
switch.
− Tapping the screen on the screen calib page: The program of the display board
works normally; the deviation between the touching point and the responding point
is small; the Maint > Screen Calib page can be entered over the screen.
− Calibrating the screen by DIP switch: The display board works normally; the
deviation between the touching point and the responding point is unfavorably big;
or the screen does not respond when being tapped.
