14.3 Measuring display for active energy
The standard display of the UMG 96-PA-MID and
the UMG 96-PA-MID+ is the measuring display
Active energy
: The standard display appears:
·After power is restored.
·After 1.5 minutes without input.
The measuring display
Active energy
shows the
legally calibrated measured values!

Overview
.
14.4 Tamper-proof meter reading cycle of the
UMG 96-PA-MID+ (as of firmware 2.10)
A meter reading cycle (load profile) describes the
measured energy over a defined period of time.
During a meter reading cycle, the meter readings
are taken every 15 minutes.

NOTE
From firmware version 2.03:
With a 1:1 setting of the current transformers,
the measured values are shown on the device
display with 3 decimal places.
The
UMG 96-PA-MID+
energy measurement
device has the function of a "tamper-proof meter
reading cycle". This means the device records:
·MID-calibrated meter readings of energy
values every 15 min. (active energy applied and
delivered).
·The energy values with increased accuracy, a
time stamp (UTC) and checksum.
·Data records (measurement data) of up to
2
years
worth of measurement recording with sta-
tus information and time interval (
15 min.
).
·Measurement data on a separate, unchangeable
partition of the internal device memory.
·Measurement data with relevant information for
legal purposes, which can be accessed via the
GridVis
®
software.
NOTE
The certified meter reading cycle storage of the
UMG 96-PA-MID+ requires a synchronization
with the legal time according to PTB-A 50.7
(Physikalisch-Technische Bundesanstalt) For
more detailed information refer to section
„14.12 Time synchronization“ on page 77
NOTE
In contrast to the
UMG 96 PA-MID
, on the
UMG 96-PA-MID+
the function
Meter reading
cycle is
tamper-proof
,
certified (from firmware
2.10)
and
·meets the requirements of PTB-A 50.7 (Physika-
lische Technische Bundesanstalt);
·synchronizes with an NTP server according to
the UTC time scale (only devices with Ethernet
module!);
·allows a time change every 15 min. via the Mod-
bus protocol.
