• Keep the air around the detector clean on the page waiting to be turned on. During the startup process, the detector will perform vibration and light self-test, please pay attention to observe whether it is normal. The above status is normal, indicating that the sound, display, light, and vibration self-test pass
• After the boot is completed, the normal gas main surface can be displayed, and the real-time gas concentration can be seen. Press the left button to view the system status information

Turn off

• Keep the air around the detector clean on the page waiting perior vibration and light scar-test, pocase pay attention to observe whether it is normal. The above status is normal, indicating that the sound, display, light, and vibration self- test pass

Charging

• The USB charging cable is plugged in when the detector is in shutdown mode, the current power will be displayed on the screen, when there is only one grid left, the LCD will pop up a low battery page every 60 seconds, and there has a voice indicating“Low battery, please charge”.
• When the battery is less than 1 grid, the detector will automatically shut down to prevent data loss inside the detector and unpredictable damage caused by insufficient voltage on the internal sensitive components of the instrument

The data is your gas concentration, after the Yes key is pressed, the alarm is saved.

Warning : You must do this in the clean air (The 02 must adjust in the N2 gas environment) , ensure there is no detected gas in the air. Or thedetect value will be wrong !

Cali Gas
Prepare gas cylinders, pressure limiting valves, flow meters, gas pipes, and calibration hoods before calibration. When the arrow in menu selection bar points to the calibration setting, press the middle confirmation key to switch to the interface for selecting the calibration setting channel; you can scootie channst be ine and dress, Are ho sir on and”    ” ” keys; After choosing the setting channel, press the OK key to enter the calibration setting page,

Open the pressure limiting valve of the cylinder with the standard concentration, and adjust the flow to 200-400ml/min. connected to our gas detector through a gas pipe and a calibration gas hood. observe the AD value displayed on the instrument, at this time, the AD value should be rising, wait for about 1 minute for the AD value to rise to the peak value and be stable and not floating. Use ” ” and ” ” to adjust the concentration value of the calibration gas. For example, if the carbon monoxide concentration of the gas cylinder is 250 ppm, you need to adjust the concentration value displayed on the instrument to 250 ppm. Click OK to save.

Calibration successful

Warning : Non professional personnel are strictly prohibited from carrying out this operation, otherwise all consequences will be borne by themselves. The tester has been calibrated uniformly when it is out of the factory. If the user wants to re-calibrate, please follow the steps strictly, first set the zero point, then re-calibrate the settings. If the user fails to operate this setting, please contact the manufacturer back in time for calibration

Use

• 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.
• 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 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.

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.
• 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.

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.

Note :The 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
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.

Notes

1. Prevent the detector from falling down or being subjected to severe vibration.
2. In the presence of high concentration gas, the detector may not be used normally.
3. Please strictly operate and use according to the instruction manual, otherwise it may cause the test result to be inaccurate or damage the detector.
4. This 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
5. If 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 surface of the machine. Otherwise, it may lead to scratches or damage on the surface of the instrument.
6. Please 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
7. Any failure or failure to be described in this manual should be contacted with our company for settlement..
8. In the explosive gas environment, the battery pack can not be dismantled or replaced, nor can the battery pack be charged. In explosive gas environment, peripheral plug-in devices without explosion-proof certification can not be used, nor can sensors be replaced.
