First of all, to understand each part of the combustible gas detector, as we can see that the combustible gas detector covers several parts : sensor brake chamber, air intake pipe, air vent, LCD screen display area, on-off key, plus and minus symbol key, menu key, exit key.

How to use the combustible gas detector?

Before making accurate measurements, we must first set the alarm signal point and the efficiency of the air pump air compressor.First of all, we should find a clean and zero pollution gas ring mirror, and do a good job in the design concept of alarm signal point : under the operation interface of accurate measurement , press the menu key to enter the performance parameter touch type, select the alarm signal point setting, and press the on/off key to confirm. Press the menu key to move the cursor to position the Senior high school low alarm signal point value, change the high and low alarm signal points, you can use the plus or minus key to expand or reduce the alarm signal point value, after setting, press the switch key to save the setting. If you do not need to set, you can press the exit key to exit the performance parameter touch.The combustible gas detector is a pump suction type combustible gas detector, so it is very important to set the pump suction efficiency: press the menu key to enter the performance parameter touch type under the touch type of the accurate measurement operation interface, select "air pump air compressor efficiency setting", and press the power key to enter the touch type, Then Press the plus or minus key to expand or reduce the efficiency of the pump, press the power key to save the settings, and press the exit key to return to the precise measurement touch type.

we should also do 0-point correction and target-point correction before inspection, because this correction requires extremely strict gas ring mirror, so it is proposed that the correction work should be carried out by professional and technical personnel. if there are no professionals, you can also communicate with the manufacturer or seller according to the telephone number listed in the instruction manual. Generally speaking, the equipment will have two kinds of Chinese and English choices, and the "language selection" can be made through the equipment prompt ".

specific method of switching on and off: specific method of 1. on and off: press the on button for three seconds, the instrument and equipment will run automatically, the light behind the LCD screen will illuminate, the bright red display light will illuminate, and the pump will start to work. After starting up, the pictures displayed are: "Haigu Security Gas Detection Expert", "Main Parameter Operation Interface" and "Sensor Initialization". The time prompt is 120 seconds. After 120 seconds, the gas accurate measurement operation interface will be entered. The specific method of 2. shutdown: press the shutdown button for three seconds under the normal and accurate measurement operation interface, the buzzer will be heard, the LCD screen display and backlight will be turned off, and the detector will enter the sleep shutdown state at this time.
