4. Operation & Function
4.1 Turn on self check and preheating process
Press the button for 4s and then release it. the LCD
screen of the detector is turned on and the welcome interface is
displayed. The detector automatically performs self-test of the
sound, light and vibration alarm signals, displays the system
information and performs the preheating countdown. The above
information can be used to confirm the integrity of the detector
performance.
4.1.1 After the detector is warmed up and
enters the power-on state, the normal detection
state of the detector is shown in Figure 1. (The
display mode varies according to the position of
the sensor, and the gas in the figure represents
methane.) Fig.1

4.2 Turn off
Under the detector is in the normal detection state, press
button, the LCD screen will prompt the user to shut down the
interface as shown in Figure 2. The user selects whether to shut
down through button. If select sure, the screen no longer
displays any information, and the detector enters Off state.

4.3.1when gas detector detects the gas less than the low alarm (
Mark: for oxygen, between the low alarm and high alarm value), g
as detector is under normal detecting state, no alarm at this time.
4.3.2 When the detected gas concentration is higher than low
alarm value and lower than the high alarm value (Note: When the
oxygen concentration is lower than the low alarm value), the
detector is in a low alarm state. The buzzer emits an alarm sound
of “beep,beep...”every 0.5s, and the red alarm light flashes
synchronously. At the same time, the gas concentration value on
the screen turns yellow and the backlight and vibrator are also
turned on remind of low alarm; press button to cancel the
audible alarm, but still display alarm information. The buzzer will
resume ringing until the new alarm is triggered, and the alarm light
and vibrator will resume operation. When the gas concentration
value detected by the detector returns below the low limit alarm
value, the gas concentration value turns green and the alarm
signal is automatically released. When the alarm is detected, the
detector is shown in Figure 4.

4.3.3 When the detected gas concentration is higher than the set
high alarm value, the detector is in the high alarm state, at this

time the buzzer emits “beep,beep,…every 0.25s”. the red
indicator light flashes synchronously, and the color of the gas
concentration value changes to red on the screen. The backlight
and the vibrator also open at the same time, indicating the high
alarm; long press the button to release the audible alarm. but
there is still an alarm message. The buzzer will resume ringing
until the new alarm is triggered, and the alarm light and vibrator
will resume operation. When the gas concentration value detected
by the detector returns below the low alarm value, the gas
concentration value turns green and the alarm signal is
automatically released. When the alarming, the detector is shown
in Figure 5.
Fig 5
4.3.4 When the detected gas concentration is higher than the test
range, the buzzer of the detector will beep normally, the LCD
screen will be on constantly, the vibrator will be normally open, and
“HHHH” will be displayed on the screen, indicating over-range. at
that time, you can press the button to release the audible
alarm.

4.5. Charging
Please charge the detector when it shows low battery or the
detector can’t be turned on due to low battery. Before charging,
please turn off the detector. After you connect the charger correctly
between the detector and AC power source, the detector will be
turned on automatically. When the battery mark on the screen is
full and doesn’t change any more, it means the charging is
completed. Please pull off the charger.
Warning: During charging status, the detector can’t detect the gas
leakage. Please do not try to charge it at testing places to avoid
fire or explosion. Please do not charge it when the detector is
working to avoid potential damage.
Note: Make sure full charge for at least once within 3 months
since production date.
