Averaging time
An averaging time can be assigned to each mean value.
All averaging times are programmed to 15 minutes, when
the device leaves the factory.
Attention!
If the averaging time, the current transformer, the
voltage transformer, the three or four wire measu-
rement or the measured value selection is chan-
ged, the ring buffer is deleted.

If the averaging time, for example, for voltage L2 should
be changed to 5 seconds, please proceed as follows:
Select mean value as
described in chapter
"select mean value".
Select averaging time of
5 seconds using key 3.
The averaging time is selectable from 5, 10, 15, 30
seconds, 1, 5, 10, 15, 30 and 60 minutes.

Duration of the measurement period
The averaging time for real power EMAX is called measu-
ring period.
Within the measuring period, the real work is measured
and divided by the time passed by. As the result, the real
power EMAX is indicated. When the measuring period is
over, the added real work is deleted.
The measuring period for real power EMAX can be set to
5, 10, 15, 30 and 60 minutes. The factory presetting is a
measuring period of 15 minutes.
Memory
The memory of the UMG 503 is split into three areas:
The event memory, the peak and lowest value storage
and the ring buffer. The event memory and ring buffer
can only be read out via PC using the programs PSWbasic
or PSWprofessional. The read out data are available in
ASCII-format, and the ring buffer data in binary format
additionally. With PSWprofessional you can create
graphics from those binary data.
In the peak and lowest value storage, the peak and
lowest values of the measurement values are saved with
date and time. All EMAX monthly peak values are saved
for each months and all tariffs. The old EMAX monthly
values are overwritten at the beginning of a new year.
In the ring buffer all measurement values, marked for
storage, are saved. The configuration of the ring buffer is
only possible with the option "Configuration UMG503".
In the event memory the following events can be saved
with date and time:
- Deleting the event memory,
- Relay output 1 on/off,
- Relay output 2 on/off,
- Breakdown and return of the auxiliary voltage,
- Breakdown and return of the measurement
voltage.
The breakdown of the measurement voltage will be
recognized, when:
- The measurement voltage is smaller than 50% of the set
primary voltage of the current transformer,
- and the breakdown lasts longer but 500ms.
Pressing key for about 2 seconds, the highest value
is deleted and you return to the first measured value
window of the measured value indication!
