Steps
1. Power on and select the operation menu language (Chinese or English)
2. Adjust the detection mode, storage mode, display mode or air pump mode as needed
3. Perform gas concentration detection and view data in real time on the screen
4. View historical data or export stored data
5. Optional temperature and humidity detection function for environment monitoring
6. Automatic calibration or Sensor target calibration to ensure accuracy
Notice
• The instrument is designed to be dust-proof and equipped with a dust filter, but the filter status needs to be checked regularly
• Working ambient temperature range is -30~ 60 ℃, humidity ≤ 95% RH non-condensing, pressure range is -30Kpa~ 200Kpa
• With overvoltage protection, overcharge protection, anti-static interference and anti-magnetic field interference functions, but still need to avoid extreme conditions
• Real-time storage or timed storage mode can be set as needed when storing data
• Up to 6 target points should be used when calibrating to ensure measurement accuracy and linearity
• Built-in 4000mA rechargeable polymer battery, pay attention to reasonable charging and discharging to prolong Battery life
