Chapter 8. Precautions
1. Multi-point detection
The composition of the air in different locations is not necessarily uniform, like the content
of pollution will certainly be different at every corner of the room. Users are better to detect
by multi-point sampling, and take the average value as reference.
2. Avoid interference
During measurement process, please try to avoid the interference of methanol / ethanol
fume, such as cigarettes, alcohol, perfume, cosmetics, skin care products (hand oil) to avoid
measurement error. Before measurement, set the monitor in good ventilation to eliminate
interference. In addition, be sure not to blow the monitor with mouth, doing so will after
the lifespan of sensors.
3. Low temperature detection
When the temperature is below zero degree, the sensitivity of sensors will decrease.
Therefore, please do not leave the monitor work in prolonged low temperature (longer than
30 minutes).
4. Ensure the air flow is stable
Gas molecules in space have been following random Brownian motion, gas distribution is
susceptible to air flow interference. As far as possible to make the air flow stable before
measurement.
5. Not used for a long time
When monitor has not been used for a long time, it will require to reboot by following the
First Time of Use procedure in Chapter 5.
