Zero calibration: When the instrument host is powered on, the instrument LCD will display the current combustible gas content in the air around the probe. If there is no flammable gas content in the air around the probe installation site, the probe display value should be 0% LEL At the same time, the output signal should be 4mA. If not, adjust it so that the probe display value is 0% LEL.
1. After the detectors are installed, they must be supervised and opened by professional and technical personnel on site.
2. After the detector is installed and adjusted once, it is not allowed to adjust or change the wiring at will, and it should be disposed according to the regulations.
3, National Standard "GB15322.2-2003" related documents stipulates that the gas detector is a semi-annual calibration (recommendation), but if the probe is not bad, there is no abnormal quality, you can calibrate once a year.
Standard gas calibration: The calibration cover of the application accessories is placed on the sensor. The probe is marked with a certain concentration of flammable gas (isobutane or methane). The display value of the probe should be gradually increased, and the value should be stable. The display value of the probe is the concentration of the standard combustible gas that is passed in. After the adjustment, the calibration is completed when the display is stable.
1. When the detector fails, it should be repaired by professional and technical personnel and reopened.
2. Observe the concentration display status of each channel frequently. If it is found that the concentration display of a certain road is always negative or that there is no gas in the field, and the concentration display is constant, it means that the zero point is not correct and should be adjusted and calibrated by the relevant technical personnel.
Gas detector daily inspection and calibration cycle (ie, calibration), combustible gas alarm needs calibration and calibration debugging cycle? Flammable gas alarm zero calibration and calibration inspection cycle at least once every 3 months.
