The four-in-one gas detector cannot display the ambient gas concentration normally after startup
After starting up, the four in one gas detector cannot display the ambient gas concentration normally. The four in one gas detector needs to be calibrated, but the sensor has not stabilized. Wait for 60 seconds and perform zero and range calibration on the four in one gas detector. If the start-up fails, it should be a common fault that can generally be resolved by checking the manual. If it still cannot be started, please contact the manufacturer. The reason why the four in one gas detector cannot be turned on is due to battery reasons. The battery power has been exhausted and the four in one gas detector is damaged or malfunctioning. It is necessary to charge and test the four in one gas detector. The four in one gas detector immediately enters an alarm state when turned on, and the sensor should be stabilized to trigger a low battery alarm. High sensitivity sensors or biased sensors need to wait for 60 seconds to display the measured gas concentration data normally.
In addition, when using a four in one gas detector in different situations, make sure that the power switch of the four in one gas detector (explosion-proof area) is turned to "OFF" before installing the battery and turning the sensitivity adjustment knob counterclockwise to the end. Place the instrument in a non flammable gas environment, turn the power switch to "ON", and the power indicator light will turn on. When the indicator light is straight on (indicating that the battery is fully charged), the instrument can detect normally. Regular cleaning and maintenance of the four in one gas detector is an important task to prevent malfunctions. Grounding should be checked regularly. If the grounding does not meet the standard or is not grounded at all, it can also cause electromagnetic interference and malfunction of the four in one gas detector. Prevent malfunctions caused by component aging. From a reliable perspective and practical experience, it has been proven that systems with a service life of more than 10 years for four in one gas detectors tend to experience an increase in failures caused by component aging. In such cases, manufacturers can be contacted for upgrades or replacements.
