Precautions for Use
● When charging the detector, please do so in a safe place and use a 5V 2A or higher charger that complies with safety regulations
● When using the detector for the first time, please fully charge the battery before use
● This detector is of pump suction type. Please do not block the air inlet and outlet of the detector to avoid clogging of the internal air pump. If the air pump fails to start after a blockage occurs, it should be shut down quickly and then restarted.
● If you need to test for a long time, please fully charge the battery first. When the battery power drops to 0%, a countdown and automatic shutdown interface will appear. You can force it to turn on, and it will automatically shut down again after 5 minutes.
● When in daily use, do not impact the detector with gas exceeding the measurement range to avoid irreversible damage.
● Do not use in harsh environments such as high temperature, high pressure or high humidity. If the humidity of the usage environment is high, filter and dehumidify before conducting the test.
● The detector should be prevented from falling from a height or being subjected to violent vibration.
● If the sensor malfunctions, please contact the after-sales service of the manufacturer.
● Under normal use, the effective service life of the sensor of the detector is 24 to 36 months. During the valid service life, the sensor should be calibrated and inspected regularly every six months or once a year (depending on the working environment) to ensure the accuracy and effectiveness of gas monitoring. Sensors that have exceeded their valid service life or are faulty must be replaced.
