Master the key points to use the composite multi-gas detector reasonably
1. How to use the composite multi-gas detector:
1. Turn on the instrument
In the measurement state, press the "1" key for about 2 seconds to turn off the instrument.
2. Low battery
When the undervoltage alarm occurs, the operator should shut down the instrument and charge it, which takes about 3-4 hours.
2. Preheating self-test of the composite multi-gas detector:
After pressing the "1" key to turn on the instrument, there will be a self-test process for the instrument's own power, sensor, and sound, light and vibration alarm function, and enter the 100-second countdown preheating. After the preheating is completed, it will directly enter the measurement status interface.
!Note: If the self-test fails, the self-test should be repeated. If it fails again, please contact us or your local agent/service provider.
