NOTE
The
UMG 96-PA-MID/MID+
has an integrated
logbook.
The logbook:
·Appears only in the MID device (see
ization of your load profile can be done using
the GridVis® software. Here, meter readings
of the active energy (applied and delivered) are
offset against previously recorded active en-
ergy measurement data and the difference is
displayed in a registration period (in Germany =
·Records password changes and changes in cur-
rent and voltage transformer ratios (CT and VT).
·Records a maximum of 48 changes with the
recording of the respective meter reading.
After 48 entries in the logbook, the device locks
the configuration of passwords and transformer
ratios. Contact the device manufacturer’s Sup-
port.
