Instructions for use
.Power on for the first time
Plug the power plug of the detector into the socket, the power indicator light will light up, and the voice prompts Welcome to use the Bodachuang Technology Voice Alarm. Preheating is in progress, please wait for minutes while the digital tube displays a second countdown.
.Standby
After the three-minute preheating is completed, the detector enters the standby state. If no gas leakage is detected, the detector's display will display once per second, indicating normal operation.
.Concentration display
When the detector detects that the concentration of combustible gas reaches, the digital tube starts to display the concentration value. When the concentration exceeds
, the digital tube displays. If the concentration is lower than the concentration, the digital tube does not display the concentration.
.Alarm
When the detector detects that the gas concentration exceeds, it will give a voice prompt. Please pay attention to gas leakage. Please turn off the gas source and give a voice alarm. The indicator light will flash. At this time, the gas valve should be closed immediately and doors and windows should be opened to allow indoor air circulation.
.Language switching
This detector has built-in Chinese and English languages. During the preheating second countdown process, press and hold the test button for seconds.
Wait for the digital tube to display, indicating that it has switched to English. . If you want to switch to Chinese, switch in the same way.
.Reference point calibration
Since the sensor is a precision device, when it is subjected to strong vibration or knocking (or when it is not used for a long time), the reference point of the sensor may change, thus affecting the accuracy of the detector. At this time, it is necessary to recalibrate the reference point, or calibrate it regularly in clean air.
The method is: preheat the detector in clean air for 10 minutes and turn off the power, then press and hold the test button and turn on the power again. After hearing the detector beep ten times (and after the red light stops flashing at the same time), Release the button, and the detector will start to calibrate the reference point and display. This process will take about a second of sampling time to complete the calibration and then it can work normally.
.Detector failure
When the internal sensor of the detector fails, the detector will alarm, the digital tube will display, and the voice prompts please pay attention to the sensor failure.
