Duration of measurement
A measurement always takes the time previously set. The duration can be entered in minutes or
seconds and can be between 5 seconds and 30 minutes. If you set a duration outside that range,
the start of the measurement will be disabled.
("Please correct your entries.")
Note:
Of course, an ongoing measurement can always be stopped manually. To stop the
measurement, click on the icon on the tool bar ("Stop measurement").
Start trigger
The measurement can be started in three different ways:
"Immediately"
1.
The measurement will start immediately after the window has been closed by clicking on
"Apply".
"Change of value"
2.
The measurement (and thus the lapse of time) will not start before the measurement value
changes.
"Threshold value"
3.
In an additional box, you can enter a value which is then used as a reference value, in
combination with the previously set unit. The measurement will start when this value is
measured by the connected sensor of the PCE-DFG N.
Alarm monitoring
You can set an upper limit and a lower limit for the measurement. When these are exceeded /
fallen below, a "silent alarm" will be triggered. This means that the alarm is recorded but does not
cause early termination of the measurement.
If alarms occur during a measurement, these can be listed after completion of the measurement.
More information can be found under "Alarms".
You have the following options:
"deactivated":
No monitoring is active.
"fracture":
Monitoring for material overload
Here, you must define an upper limit and a stage value in per cent. If the upper limit is
reached or exceeded during a measurement, this will be recorded as an alarm. If from
this time on the measured value drops to or below the percentage set as the stage
value, an alarm will be recorded every time this occurs.
"within" / "beyond":
For these two types of monitoring, an upper and a lower limit must be defined.
Depending on the selected type of alarm, an alarm will be triggered when the measured value is
„within" or „beyond" the selected range.
