•
Do not turn off the monitor during the initial clear. If it is turned off during the initial clear and
turned on again, abnormal operation may occur.
• After the initial clear, perform a calibration.
•
In a normal air release environment, CO2 concentration is hundreds of ppm. Since the reading is
not zero, even in the normal state, attention is paid.
• If there are many people and ventilation is insufficient in the area, CO
2
concentration may exceed
1000ppm (0.1 vol%).
