ALARM
The meter features an audible alarm which will give warnings when the CO
2
concentration exceeds
the set limit. There are two settable limits, an upper limit that initiates the alarm and a lower limit to
stop the alarm.
The meter emits beeps and displays the fan icon on the display when the CO
2
level goes over the
upper limit. The audible alarm can be stopped by pressing any key or it automatically stops when
CO
2
reading falls below the lower limit.
If the beeper is temporarily shut down, it will sound again when readings fall below lower limit and
then go over the upper limit again or it the user presses the RESET button for more than 1 second
to activate it.
The fan icon keeps flashing when beeps are manually shut down. It stops only when readings fall
under the lower limit
