When the detector is turned on, the LCD screen is in the standby state of displaying four concentrations of EX gas, O2, H2S and CO in real time. 5.2 EX alrm When the concentration of EX gas is detected to be higher than the low alarm value set by the system, the detector will broadcast the voice "Please note that the concentration of EX gas exceeds the standard" and continue to simulate the alarm 10 sound; the alarm lamp above the detector and the internal vibration motor will be turned on simultaneously; When the alarm value is low, the voice, light and vibration alarm states disappear. 5.3 O2 alarm When the concentration of O2 is detected to be lower than the low alarm value set by the system, the detector will broadcast the alarm signal "Please note that the concentration of oxygen is too low", which is higher than the high alarm threshold set by the system. The detector will broadcast the alarm signal "Please note that the concentration of oxygen exceeds the standard" and always simulate the alarm sound; the alarm light on the detector will voice the alarm signal. When the concentration of O2 gas is monitored by the detector and restored to the normal value, the alarm state of voice, light and vibration disappears. Note: O2 concentration in normal air is 20.9%. Users can adjust the value of low and high alarm according to actual needs. 5.4 H2S alarm When the concentration of H2S gas is detected to be higher than the low alarm value set by the system, the detector will broadcast the voice "Please note that the concentration of H2S gas exceeds the standard" and continue to simulate the alarm sound; the alarm lamp above the detector and the internal vibration motor will be turned on simultaneously; When the alarm value is low, the voice, light and vibration alarm states disappear. 5.5 CO alarm When the concentration of CO gas is detected to be higher than the low alarm value set by the system, the detector will broadcast the voice "Please note that the concentration of CO gas exceeds the standard" and continue to simulate the alarm sound; the alarm lamp above the detector and the internal vibration motor will be turned on simultaneously; When the alarm value is low, the voice, light and vibration alarm states disappear. 5.6 Alarm data storage After the detector triggers the alarm, when the detection alarm gas restores to the normal threshold set, the detector will save the current alarm information to the internal storage of the detector, 11 and according to the user set low concentration alarm threshold, high concentration alarm threshold can be divided into low and high alarm. The user can search through the alarm in the menu. O2 AlarmL 19.4% 18.8.3 2 12:27:40 Up Ente r Dowm NoteThe alarm voice support Chinese or English, as same as the language you choose. Warning 1. The detector only alarm when it is detecting; 2. Do not charging detectors at the gas monitoring site to avoid fire or explosion caused by sparks during the plugging process. 3. Try not to charge the detector on startup, so as not to affect charging speed. 4 The detector has the function of intelligent tracking zero point. Please turn on under the condition of clean air. VI. Notes 1Prevent the detector from falling down or being subjected to severe vibration. 2In the presence of high concentration gas, the detector may not be used normally. 3Please strictly operate and use according to the instruction manual, otherwise it may cause the test result to be inaccurate or damage the detector. 4This product should not be stored or used in environments containing corrosive substances (such as chlorine of relatively high concentration) or in other harsh environments, including too high or too low temperature, high humidity, electromagnetic field and strong sunlight exposure 5If there is dirt on the surface of the instrument after long-term use, please gently wipe it with clean soft cloth dipped in water. Do not use corrosive solvents and hard materials to wipe the 12 surface of the machine. Otherwise, it may lead to scratches or damage on the surface of the instrument. 6In order to ensure the accuracy of detection, the detector should be calibrated regularly, and the verification period should not exceed 1 years. 7Please unload the lithium batteries and sensors of the discarded portable gas detector and send them to the designated location or return to our company. Do not throw them into the garbage can at will 8Any failure or failure to be described in this manual should be contacted with our company for settlement. 9In the explosive gas environment, the battery pack can not be dismantled or replaced, nor can the battery pack be charged.
