Using the Multi-PID 2
A soft key is used for acknowledging alarms and is named “ accept ” .
If no alarm exists, then the “ accept ” key is not shown. To clear the
alarm, press the “ accept ” key. Once acknowledged, the alarm indi-
cators are cleared. The alarm status will remain until the alarm condi-
tion clears.
The Multi-PID 2 updates the instantaneous concentration once every
second.
Following every update, the instantaneous concentration is compared
to the REAL alarm level, and if exceeded, an alarm is triggered.
In Interval mode, if a 15-minute average exceeds the STEL, a STEL
alarm is generated. The TWA alarm is generated when the current
average of concentration, since the TWA was last cleared, has excee-
ded the TWA exposure limit.
During calibration, all alarms are disabled. Once the calibration is
complete, the alarms are re-enabled.
