Application

Tips for using gas detectors

• Carefully read the instruction manual corresponding to the gas detector before operation, and be familiar with the performance and operation methods of the machine.
• Check whether the battery power is sufficient. If the battery power is found to be insufficient, replace the battery in time.
• Check whether the air filter of the air inlet is blocked by debris, and the blockage needs to be cleaned or replaced.
• Press and hold the start button for three seconds during startup to enter the self-test state, and observe whether the low alarm value and high alarm value of the detector are set accurately (the first-level alarm of CO detector is 50ppm, the second-level alarm is 100ppm; the oxygen detector one The first-level alarm reports 19.5%, the second-level alarm reports 22%; the first-level alarm of the hydrogen sulfide detector is 10 ppm, and the second-level alarm is 15ppm).
• During the self-inspection during the boot process, you should listen to the grading alarm sound and light alarm and vibration alarm for accuracy.
• Observe whether the initial value is accurate after starting the machine under fresh air conditions (the initial display of the CO detector is 0 ppm; the initial display of the O2 detector is 20.9%; the initial display of the hydrogen sulfide detector is 0 ppm).
