10. It has one-click factory reset, self-programming to set alarm parameters, STEL and TWA functions, and two modes of detection and patrol.
Principle
The detector adopts the pump-suction Sampling method, and the built-in micro-sampling pump sucks the environment gas into the detection gas path. After the gas is pretreated, it reaches the core infrared NDIR Sensor. Based on the absorption characteristics of specific gases to infrared light, the Sensor accurately calculates the concentration value of carbon dioxide by measuring the change of absorbed Light intensity. The built-in EFM ultra-low power 32-bit ARM processor processes the Sensor signal, and uses High Accuracy Amplifier and temperature and pressure compensation algorithms to ensure that accurate and stable concentration readings can be output under different environment conditions, and realizes functions such as alarm and Data storage.
Applications
Environment monitoring, confined space operation, industrial safety, laboratory research, warehousing and logistics, fire rescue, municipal engineering
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select detection mode: Select normal detection mode or patrol mode through the menu.
3. Set the sampling pump gear: According to the detection needs, set the sampling pump to low, medium or high level in the menu.
4. Start detection: The sampling tube is inserted into the area to be tested, and the instrument automatically samples and displays the real-time concentration.
5. Data viewing and export: You can view historical data, STEL/TWA values through the menu, or export data by connecting to a computer through the USB interface.
6. Calibration and setting: perform zero-point calibration, multi-point calibration on demand, or set alarm parameters in the self-programming menu.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Please read the manual before use to ensure that it is used within the range of Ambient Temperature (-30~ 50 ℃) and Humidity (10~ 95% RH without condensation) allowed by the instrument.
* The instrument is explosion-proof design (Exia II CT4), but should be used in the specified hazardous place classification, strictly prohibited in the environment beyond the Explosion-proof level.
* Avoid strong impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
* Regularly calibrate the instrument to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
* The sampling pump and gas path have automatic cleaning function, but after using high concentration gas for a long time, it is recommended to run the instrument in clean air for cleaning.
* When charging or USB data transfer, please ensure that the environment is safe and avoid in a potentially explosive gas environment.
When storing the instrument, it should be placed in a drying and cool place to avoid extreme temperatures (storage temperature -30~ 70 ° C).
If the instrument malfunctions, please do not disassemble it yourself. You should contact a professional for maintenance.
