How do I replace the sensor on a combustible gas detector?
1, Instructions for using a composite multi gas detector:
1. Turn on the instrument
When the device is turned off and the battery is fully charged, press"
In the measurement state, press the "1" key for about 2 seconds to turn off the instrument.
2. Low battery
When the battery level of the instrument drops below the preset value, an undervoltage alarm will be triggered, indicating to the operator that the battery is low and needs to be charged. When there is an undervoltage alarm, the battery symbol flashes together with the sound alarm. When the battery is depleted, the instrument will automatically shut down.
When an undervoltage alarm occurs, the operator should shut down the instrument and charge it for approximately 3-4 hours.
2, Preheating self-test of composite multi gas detector:
After pressing the "1" key to turn on the instrument, there will be a self check process for the instrument's own battery level, sensors, and sound and light vibration alarm function. It will enter a 100 second countdown preheating, and after preheating, it will directly enter the measurement status interface.
Oh! Attention: If the self-test fails, it should be repeated. If it fails again, please contact us or your local agent/service provider.
3, Measurement mode of composite multi gas detector:
Adopting a free diffusion detection method, the instrument can be fixed on a belt or held in hand during normal operation. Once turned on, the instrument will continuously measure, and the surrounding air can enter the sensor through diffusion. Usually, the flow of air can directly send the measurement target gas into the sensor, and the sensor will react to the concentration of the gas and provide measurement results. The principle of diffusion detection is to directly detect the gas concentration around the instrument using the above methods. The advantage of diffusion detection is its fast response time. If remote detection of gas at the sampling location is required, it is necessary to use inhalation for measurement. In this case, the instrument needs to use a calibration cover and an optional air pump. When using the calibration cover, it should be ensured that the direction of gas collection is in the direction indicated by the arrow.
