In the display, press ADJ key, to reset the relay action limit. The last words of last row
might show UP, press ADJ key will increase the setting limit. Press UPDN key, the word
will change to DN; press ADJ key will decrease the setting limit.
Note: this function is available in relay output model only.
Press NEXT key to enter next function.
In the display, press ADJ key, to reset the relay release limit. The last words of last row
might show UP, press ADJ key will increase the setting limit. Press UPDN key, the word
will change to DN; press ADJ key will decrease the setting limit.
Note: this function is available in relay output model only.
Press NEXT key to enter next function.
In the display, press ADJ key, to reset the humidity. The last words of last row might show
UP, press ADJ key will increase the setting limit. Press UPDN key, the word will change to
DN; press ADJ key will decrease the setting limit.
In order to improve the accuracy of GTF300-AQ/VOC, please adjust humidity. The default
relative humidity of gas detector is 65%RH with adjustable range from 40%RH to 80%RH.
Press NEXT key to enter next function.
In the display, press UPDN and ADJ keys at same time, to enter calibration function.
Press NEXT key to jump calibration function and enter next function.
Warning! Except necessary, do not execute calibration. It is necessary to execute calibration
after power on 7 days. An error operating should loss accuracy.
In the display, user has to finish calibration.
Press ADJ key, to meet ambience CIAQ
.
In the fresh air, 1 is a recommended
value. But in some place, user might use a portable air quality detector to know
the ambience CIAQ. During the calibration the ambience CIAQ must be below
CIAQ 70. The last words of last row might show UP, press ADJ key will
increase the calibrating value. Press UPDN key, the word will change to DN;
press ADJ key will decrease the calibrating value.
Press NEXT key to finish calibration and enter next function.
In the display, press UPDN and ADJ keys at same time, to enter calibration function.
Before the calibration, user needs prepare an ampere meter and makes series into analog
current loop.
Press NEXT key to jump calibration function and enter next function.
Warning! Except necessary, do not execute calibration. It is necessary to execute calibration
after power on 24 hr. An error operating should loss accuracy.
Note: this function is available in analog output model only.
In the display, user has to finish calibration.
The last words of last row might show UP, press ADJ key will increase the
current output. Press UPDN key, the word will change to DN; press ADJ key
will decrease the current output.
Press NEXT key to finish calibration of 4 mA and enter next function.
