4.2.9. Alarm handling
For upper and lower alarm limits, individual alarms as well as
collective alarms can be specified. If the collective alarm function is
activated, an alarm is triggered as soon as the alarm limit of an
alarm is exceeded, if this alarm is assigned to the collective alarm.
The testo 6383 monitors limit values with the help of relays. If a
reading is outside the limit values, a relay to be specified by the
user is switched.
If the reading reverts to more than a specified hysteresis below or
above the limit value, the alarm is cancelled.
In addition, information about the occurrence of error/status
messages can be provided by means of a collective alarm relay,
see 4.5 Status, warning and error messages.
If multiple alarm messages are activated at the same time,
the last alarm is shown. If the alarm is cancelled again, the
previous messages are no longer shown.
