Instructions before using the gas detector
① Carefully read the instruction manual corresponding to the gas detector before operation, and be familiar with the performance and operation method of the machine.
② Check whether the battery power is sufficient. If the battery power is found to be low, replace the battery in time.
③ Check whether the air filter at the air inlet is blocked by debris, and the blockage needs to be cleaned or replaced.
④ During the self-inspection during the startup process, you should listen to whether the graded alarm, sound and light alarm, and vibration alarm are accurate. If they do not meet the requirements, the settings are not allowed to be used, and should be corrected immediately.
⑤ When starting up, press and hold the start button for three seconds to enter the self-test state, and observe whether the low alarm value and high alarm value set by the detector are accurate (the first-level alarm of the CO detector is 50ppm, and the second-level alarm is 100ppm; Level 1 alarm 19.5%, level 2 alarm 22%; hydrogen sulfide detector level 1 alarm 10 ppm, level 2 alarm 15ppm), if it does not meet the requirements, the settings are not allowed to be used, and should be corrected immediately. During the self-inspection during the start-up process, you should listen to whether the graded alarm, sound and light alarm, and vibration alarm are accurate. If the settings do not meet the requirements, the settings are not allowed to be used and should be corrected immediately.
⑥Observe whether the initial value is accurate after turning on the machine under fresh air conditions (the CO detector initially displays 0 ppm; the O2 detector initially displays 20.9%; the hydrogen sulfide detector initially displays 0 ppm). revision.
