10. Provide two detection modes of normal detection and patrol, with fault self-diagnosis and Sensor status prompt functions.
Principle
The Portable oxygen detector uses a pump-suction Sampling method, which sucks the environment gas into the instrument through a built-in micro-sampling pump. The oxygen component in the gas reacts with the imported Electrochemical sensor inside the instrument to generate an electrical signal proportional to the oxygen concentration. The signal is amplified and conditioned by a High Accuracy, Low Temperature Drift amplifier and a stable power processing circuit, and then performed by a 32-bit ARM processor for data processing, temperature and pressure compensation. Finally, the accurate oxygen concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Environment Monitoring, Confined Space Operations, Industrial Safety, Emergency Rescue, Mining, Petrochemicals, Laboratories
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. Mode selection: Select the normal detection mode or patrol mode through the menu.
3. Sampling detection: According to the detection environment, adjust the sampling pump to the low, medium or high position through the menu for sampling.
4. Data viewing: View oxygen concentration values, MAX Maximum, STEL, TWA and trend charts in real time on the screen.
5. Data storage and export: The instrument automatically stores the detection data, and the data can be exported by connecting to the computer through the USB interface.
6. Calibration and setting: Regularly perform zero or multi-point calibration through the menu, and can self-program to set alarm parameters and other functions.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) or Humidity (10~ 95% RH without condensation).
Avoid strong impacts or drops on the instrument to prevent damage to the Sensor or internal circuitry.
Periodically calibrate the instrument to ensure the accuracy of the test data.
* When used in potentially explosive environments, it is necessary to ensure that the instrument explosion protection mark (Exia II CT4) meets the on-site explosion protection requirements.
* The sampling tube should be kept clean and open to avoid clogging affecting the sampling effect.
* The instrument has a built-in battery, please use the matching charger when charging, and keep away from high temperature and fire sources.
* If the instrument malfunctions or Sensor failure prompts, the Sensor should be repaired or replaced in time.
* When not in use for a long time, please turn off the instrument and store it in a drying and cool place.
