9.2.1.3.3 Alarms
"Digital" or "digital
LP" mode
WA
A "high" at the universal input triggers a "warning".
AL
A "high" at the universal input triggers an "alarm".
SW
A "high" at the universal input triggers a "fault warning".
SA
A "high" at the universal input triggers a "fault alarm".
All other modes
Warning Value low
A warning is triggered, if the measurement value
drops to or below this value.
Value high
A warning is triggered, if the measurement value
meets or exceeds this value.
Alarm
Value low
An alarm is triggered, if the measurement value
drops to or below this value.
Value high
An alarm is triggered, if the measurement value
meets or exceeds this value.
Hyst %
Hysteresis for the all-clear in the event of an alarm/warning (e.g.
Hyst=5%, alarm or warning at 100 -> all-clear at 95) or reset the
trigger (e.g. Hyst=5%, level = greater or equal, trigger at 100 -> reset
at 95)
9.2.1.3.4 Trigger
If an universal input is operated in digital mode or LP digital mode, there are two different types of
triggers:
l
Event trigger (MS, XM)
In contrast to the level triggers, the relevant operation (e.g. start measurement) is only
executed once when the trigger event occurs. With the help of the "Edge" configuration
parameter, it is specified whether the rising, falling or both edges initiate the trigger event.
l
Level trigger (QU, SL, ON)
A "high" at the universal input initiates the trigger. A "low" at the universal input resets the
trigger. The relevant operation (e.g. fast recording) is executed as long as the trigger is active.
The option selected via the "Edge" configuration parameter is not relevant to the level trigger.
If it is necessary for the trigger to be initiated by a "low" at the universal input and for it to be
reset by a "high", the input signal must then be inverted using the "Invert" configuration
parameter located in the "Basis" tab.
