No.
Phenomena
Reason
Solutions
1
The measured value is
not within the expected
value.
1.1
The sensor is drifted by time.
Re-calibrate the sensor
1.2
The sensor was in a high humidity
environment (> 90% RH) for more
than 03 days continuously.
Place the sensor in low humidity for
its recovery. It may take up to 30
days to recover. If the sensor cannot
recover after 30 days, please replace
the new sensor module.
2
The measured value is
always zero or near zero.
2.1
The sensor module was removed.
Please check the sensor.
2.2
The sensor is at the end of its life.
Replace the sensor module
3
The voltage output is 0V
or random noise
3.1
The wiring problem
Check the wiring and connector
M12.
Check power supply.
3.2
The sensor is faulty
Contact manufacturer.

Re-calibration
The gas sensor may be drifting over time. Please check
to identify the interval time for the re-calibration
sensor. Please follow the calibration procedure as in above section.
Approx. 6-12 months
Recommend to use other rope (plastic rope or stainless steel rope) to hang the sensor, it will reduce the tension
force of the signal cable.
