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 20 mA and enter next function.
In the display, user can read out the used life time of detector. Normally, the sensor of
detector has 1,000 days life time. It is necessary to renew the sensor beyond that.
Note 1: due to QC procedure, the used life time might be more than 1 day, but it should be
less than 30 days.
Note 2: Life time meter count up during power on only. If the detector is idle for a long
time, or used in an environment with high pollution, frequentative power on and off, the
lifetime will be shortened even the meter less than 1,000 days.
Press NEXT key; the display will back to the CIAQ display.
3. Alarm message
The concentration of gas is lower than buzzer low limits or higher than the buzzer high limit, the detector not only
has audible alarm but also provide clear alphanumeric alarm message for users.
It is the CIAQ high alarm display.
Press NEXT key, the buzzer will mute and the display will back to the normal display. If
the CIAQ is still higher than buzzer high limit, this message and audible alarm will come
again, that will disappear until the CIAQ is lower than the buzzer high limit.
4. Warning message
The GTF300-AQ/VOC gas detector may auto-off under low or high specified voltage.
If the gas detector is
auto-off, it cannot work for detection.
At some of case, the detector cannot work but will provide warning message
which reminds user to check the detector or its system.
Due to input voltage lower than specified, the detector cannot work.
Due to ambience temperature higher than specified, the detector cannot work.
5. Introduce CIAQ
GTF300-AQ/VOC can detect hydrocarbon compounds in the air, especially high sensitive of hydrogen and transfer the
CIAQ (Composite Index of Air Quality) shown on the display. CIAQ define that fresh air and/or zero air is "1".
According to concentration of hydrocarbon compounds and hydrogen in the air, the CIAQ is unlimited in theory.
Applicant in the living, when concentration of hydrocarbon compounds over some limit in the air, the sense of smell
will not have multiple effects, therefore CIAQ is designed in reasonable range in living. Please refer table as below:
