ALARM
The meter features an audible alarm that warns
the user when the CO2 concentration exceeds
the programmed limit. Users can set 2 limits: a
CO2 level that requires ventilation (See P1.
3
in
setup for setting alarm limits) and a lower CO2
level when ventilation is no longer required
(See P1.
2
in setup CO2 normal limit).
During high alarm, the meter emits an 80dB
beep and displays the fan icon on the LCD. The
alarm can be temporarily stopped by pressing
any button, or it will automatically stop when
the CO2 level falls below the lower limit.
If the alarm is temporarily silenced, it will
resume if the CO2 level fall below the lower
limit then rises above the upper limit again, or if
the “
RESET
“ button is pressed to re‐activate the
alarm.
The fan icon remains flashing even if the beeps
are silenced. The icon only stops flashing when
the CO2 level fall below the lower limit (Fig.3)
