10. With self-programming function, alarm parameters, STEL and TWA functions can be set, and two modes of detection and patrol are provided.
Principle
The Portable carbon monoxide detector uses the pump-suction Sampling method, which draws environment gases into the instrument through a built-in micro-sampling pump. The gas comes into contact with the built-in imported Electrochemical sensor, which converts the carbon monoxide concentration signal into an electrical signal. The electrical signal is amplified and processed by a High Accuracy, Low Temperature Drift amplifier and a stable power processing circuit, and finally analyzed and calculated by an EFM ultra-low power 32-bit ARM-based processor. The accurate concentration value is displayed on the screen and an alarm is triggered when the concentration exceeds the standard.
Applications
Environment monitoring, confined space operation, industrial safety, emergency rescue, occupational health
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 through the menu, or connect to a computer through the USB interface to export data.
6. Calibration and settings: Regularly perform zero-point calibration or multi-point calibration through the menu, and can set parameters such as alarm value, STEL, TWA, etc. as needed.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
• Before use, please ensure that the instrument is fully charged and used within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
• Avoid long-term use in strong electromagnetic interference, high concentration dust or corrosion gas environment to prevent damage to the Sensor.
• The instrument has an automatic fault prompt function. If an alarm prompt appears, please check the status of the instrument or Sensor according to the prompt information.
• Regularly calibrate the instrument to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
• The sampling tube should be kept clean and unblocked to avoid bending or blockage, which will affect the sampling effect.
• Instruments are designed to be explosion-proof, but must not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
• Data storage space is limited, please export data periodically to avoid overwriting.
• The instrument has a built-in sampling pump. After long-term use, it is recommended to use the automatic cleaning function to clean the air circuit.
