Logging
4.6.1
Max./Min. Log
The iMeter 6 records the
Max. Log
and
Min. Log
of
This Month
(Since Last Reset)
and
Last Month
(Before Last
Reset)
with timestamp for the parameters in
. Each log includes the relevant parameter value and its timestamp. The recorded data is stored in the device’s
non-volatile memory and will not suffer any loss in the event of power failure. All of the maximum and minimum
data can be accessed via the Front Panel, Web Interface or through communications.

Peak Demand Log
is used to specify the Max./Min. Log self-read operation.
Please refer to
Section 4.2.5
for a complete description of the
Self-Read Time
and its operation. The Max./Min.
Log of This Month (Since Last Reset) can be reset manually via the Front Panel, Web Interface or communications.

Peak Demand Log
The iMeter 6 stores the
Peak Demand
of
This Month
(Since Last Reset)
and
Last Month (Before Last Reset)
with
timestamp for Ia, Ib, Ic, kW Total, kvar Total and kVA Total. All Peak Demand data can be accessed via the Front
Panel, Web Interface or communications. Please refer to
Section 4.2.5
for a complete description of the
Self-
Read Time
and its operation.
The Peak Demand of This Month can be reset manually via the Front Panel, Web Interface or communications.

Interval Energy Recorder (IER) Log
The iMeter 6 provides an Interval Energy Recorder capable of recording the interval energy consumption for
kWh/kvarh Import/Export and kVAh. If the users wish to record the accumulative energy values instead of the
interval energy consumption, the Data Recorder should be used instead. The recorded data is stored in the
device’s non-volatile memory and will not suffer any loss in the event of power failure.
The programming of the IER is supported via the Web Interface or communications. The IER provides the
following setup parameters:

are all non-zero. When the present time meets or exceeds the
Start Time
, the IER will start to record.
