CAUTIO

A loss of power while the power meter is in standby mode has no effects.
CAUTIO
N
Although the start of processing in this case is later than the start time that was
set, the processing assumes that the measured values during the interval were
"0". The power meter stops measuring at the scheduled stop time.

6.3 Integrated Measurement Mode and Demand
Measurement Mode
(1) Data and setting conditions that are retained
1. Measurement data
If the display data was being held when power was lost, all of the data that
was being held is retained.
Integrated measurement mode: The minimum/maximum values and the
integrated values just before power was lost are retained.
Demand measurement mode: The minimum/maximum values and the demand
values from the previous demand period, and the integrated values are
retained.
2. Setting conditions
The setting conditions when the power was lost are retained.
(2) Operation after power is restored
1. If power was lost while in standby mode
a. Operation when power is restored prior to the time set for the start of
processing
The power meter goes back into standby mode and then begins integrated or
demand measurement when the set time arrives.
b. Operation when power is restored after the time set for the start of
processing
The power meter begins integrated or demand measurement as soon as the
power is restored.
2. If power was lost while integrated measurement or demand measurement was
in progress
The power meter does not keep track of the elapsed time for integrated
measurement while the power is off. (Integrated measurement is paused, not
stopped.)
After power is restored, a message indicating that a power failure had
occurred is displayed on the screen and integrated measurement resumes.
(Pressing any key causes the message to disappear.)
