Frequently Asked Questions M10i cannot connect to Wi-Fi? What is the principle of particle sensors? Why the readings are inaccurate? Why the TVOC reading gets higher at night? Must the ventilation/calibration done outdoors? Can I calibrate the temperature and humidity sensor for M2000 2nd generation? Lemon/Orange impact on HCHO/TVOC Should the device be fully charged before calibration? Can I put the device outside when the temperature is extremely low? why does the readings go up when the humidifier is on?
M10i cannot connect to Wi-Fi? Please make sure you have followed the correct steps configure the setting: 1. Hold the reset button until the WIFI symbol shows increasing. 2. Add device through App. 3. Input Wi-Fi password. 4. It will keep loading, but once the Wi-Fi symbol on the device stops increasing or flashing, that means it has been connected to Wi-Fi successfully.
What is the principle of particle sensors? Laser particle sensor can obtain the number and quality of suspended particles in the air per unit volume, which is called particulate matter concentration. Meanwhile, it can output as a digital interface.
Why the readings are inaccurate? The air does not circulate during storage and transportation, to achieve the best performance of the device, it needs to be placed in the outdoor ventilation for at least 6 hours before the first use. Meanwhile, each sensor has individual differences, just like everyone is with different alcohol metabolic abilities, so a small number of sensors may require longer ventilation. In this situation, to extend the ventilation time will be advised.
Why the TVOC reading gets higher at night? There are many factors that affect TVOC readings. When we go to sleep at night, we usually close the doors and windows and stop walking around. This reduces the circulation of air and makes the readings higher than during the day. In addition, the sweat produced during sleep, and the exhaled gas also contains a variety of VOCs, which also increases the concentration of TVOV.
Can I calibrate the temperature and humidity sensor for M2000 2nd generation? The displayed reading is higher than the normal temperature because in addition to the ambient temperature, many internal sensors and electronic components also generate heat. Currently we are not able to have a temp offset calibration. The temperature sensor was not broken, just the accuracy (±2℃) not so high comparing to some professional thermometer.
Should the device be fully charged before calibration? Yes, the device should be fully charged and turned on before placing it in a ventilated area for 6 hours. Can I put the device outside when the temperature is extremely low? No, the device should be placed in a room temperature with a common range of 18°C to 28°C why does the readings go up when the humidifier is on? Ultrasonic humidifiers release water droplets instead of water vapor.
