Machine workflow: in the shutdown state, long press the menu button
to turn on. The machine enters the preheating state interface, and
the backlight lights up at the same time. After 5 seconds the
system enters the self-check, during the self-check, the LED lights
flash, the buzzer chirps, and the vibration motor vibrates. After
the preheating is completed, it enters the measurement state.
Environmental gases can be measured in a measurement state. The
screen interface shows oxygen (O2), hydrogen sulfide (H2S), carbon
monoxide (CO), and gas (EX) concentration values. Can be customized
according to customer needs. Long press the menu button to turn off
after you've finished using it. The basic operation of the detector
