- 1.2 Product description

1.2.9 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 6651 monitors limit values using 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

chapter 1.5, page 76

).

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.

Example

If the condensation of the probe begins, the "Condensation"
message appears on the display and the "Start" status
display. If the condensation is over, the status display
changes from "Start" to "End".
