As soon as the configuration has been written into the device, a first measured value is recorded (in
the sample:Start recording at 12.00 p.m.). As per configuration, this measured value is compared every
second with the current measured value, till the difference is 0.5 bar. This first happens at 13.15. The
next recording takes place at 13.30, etc... Independent of that, each fixed Save-Interval (1 hour), an
additional recording is done.
At 17.00 both a recording at the fixed Save-Interval as well as an event recording occur
simultaneously. Only one measured value is stored however.
Warning!
With the Event "Save if delta Channel > Val1” the interval "Recording interval after Event" is always
taken into account. This means that in the following configuration example, the interval time is always
1 second, that is both for event detection as well as for recording!
Event Detect Interval = 5 seconds
Recording interval after Event: = 1 second
The time value specified under Fixed Save-Interval is however independent and in addition to the
above mentioned interval.
