When the gas concentration detected by the detector is lower than
the set alarm value (Note: when the oxygen concentration is
higher than the low alarm value and lower than the high alarm
value), the detection status bar only displays the concentration
Value, no abnormal display.
When the gas concentration detected by the detector is higher
than the set low alarm value (Note: when the oxygen
concentration is lower than the set low alarm value), the detector is
in the
low alarm state
, the gas concentration value display color
changes to red, and the status bar displays "
L
", and the buzzer
beeps at 0.5s intervals, the alarm lights on both sides of the
screen flash synchronously, and the vibrator vibrates. If the screen
is in the off state, the screen lights up at the same time.
When the detector detects that the gas concentration is higher
than the set high alarm value, the detector is in
the high alarm
state
, the gas concentration value display color changes to red,
the detection status bar displays "
H
", and the buzzer emits "di" at
an interval of 0.25s. The beep sounds, the alarm lights on both
sides of the screen flash simultaneously, and the vibrator vibrates.
When the detector detects that the gas concentration is higher
than the sensor range, the detector is in
the over-limit state
, the
gas concentration value is displayed as red "
HHHH
", the detection
status bar displays "
OV
", and the buzzer interval 0.25s sends out a
"di" beep, the alarm lights on both sides of the screen flash
simultaneously, and the vibrator vibrates.
