Process of Over-range incorrect operation
Users should avoid using gases which exceed the measure range to impact the sensor, because it will affect the
lifespan and sensitivity of the sensor, even, "poison" the sensor. If there is any over-range incorrect operation makes
the detector displaying an concentration at a large reading, the remedy is to take the device out of the environment
immediately and put it in clean air for over half an hour, and then observe the reading, if it keeps going down, then wait
until the reading back to zero before powering it off, and do the zero point calibration next time before using it. If the
reading maintained at full scale, user should send the device back to manufacturer or agent for repair or replacing the
sensor.

Note
*
If detector is used for the gas cylinder detection, considering the high pressure in the cylinder, please use a
pressure regulator, and keep it as the below data:
Flow rate: 800mL~1L/minute
Pressure: 0.1MPa or 1Bar
*
Please put the detector in clean air for about 5 minutes and waiting for the data falling down to normal before
turning it off after measurement.
