How to use the gas tester?
one, before use
1. Carefully read the instruction manual corresponding to the gas tester 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-inspection 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; the oxygen detector The first-level alarm is 19.5%, the second-level alarm is 22%; the hydrogen sulfide detector has a first-level alarm of 10 ppm, and a second-level alarm is 15 ppm). 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.
6. Observe whether the initial value is accurate after starting 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). If the displayed value is inaccurate, it is strictly forbidden to use it. Edit now.
two, during use
1. When using the gas tester, it should be worn as close to the mouth and nose as possible, such as the front neckline of clothes, jacket pockets, etc. It is strictly forbidden to place the alarm in pockets and other places that are not easy to see, which will affect the detection value.
2. Try to avoid collisions during use, which may cause abnormal detection data.
3. Gas tester sensors and other components are precision components. Do not open the cover of the adjusted instrument casually. During use, pay attention to waterproof and impurities to prevent abnormal data.
4. If there are abnormal situations such as continuous flashing of the indicator light, no numerical display on the display screen, no action in the area where the gas exceeds the standard, or a large gap, etc., the operation should be stopped immediately, and the operation should be evacuated to a fresh air area to observe the problem, and timely exclusion, otherwise it is strictly prohibited to continue to use.
three, after use
1. After using the gas tester, press and hold the off button, the display will display a 5-second countdown, and the LCD will display "off" after the countdown ends, and then the instrument will have no display, and the instrument will shut down. It is strictly forbidden to directly deduct the battery to force it to shut down.
2. After the gas tester is turned off, the dust attached to the surface should be cleaned, and the equipment should be cleaned.
3. When the gas tester does not work for a long time, it should be turned off and placed in a dry, dust-free environment that meets the storage temperature.
4. The gas tester implements a special person management system to prevent the loss of the instrument due to loss and other situations, which will affect the normal use.
