Alarm Signals
During each measurement period, the gas concentration is compared
with the programmed alarm limits (gas concentration alarm limit
settings). If the concentration exceeds any of the preset limits, the
loud buzzer and red flashing LED are activated immediately to warn
you of the alarm condition.
In addition, the instrument alarms if one of the following conditions
occurs: battery voltage falls below a preset voltage level, failure of
the UV lamp, pump stall, or when the datalog memory is full.
