Power monitor function
(installed as an option)
Instantaneous power waveform display
(power monitor function)
This function works with the single-phase
two-wire, single-phase three-wire, three-
phase three-wire, three-phase four-wire and
DC connection modes, making it possible to
measure systems ranging from four single-
phase two-wire systems, to a combination of
one three-phase four wire system + one single-
phase two-wire system. Calculations can be
performed on partial waveforms selected for all
waveforms in storage by using the A-B cursors,
and results can be displayed in a single screen.
Numeric results can be displayed as overlays in
the waveform screens.
This function multiplies captured voltage and
current waveforms and displays the result as an
instantaneous power waveform. (Display in real-time
is possible through hardware integration processing
for speed ranges up to 10 ms/DIV. For faster ranges,
power waveform display is calculated after first
storing waveforms in memory.) Power waveform
display allows up to 8 waveforms to be displayed
in addition to voltage and current waveforms, and
a total of up to 16 waveforms can be displayed
simultaneously (8 voltage/current channels, and
8 power waveforms). Using the appropriate input
units, values such as temperature and frequency can
be simultaneously observed on channels for which
power calculations are not being performed.
Power monitor specifications and options
Trend graph display
(power monitor function)
Using this function, you can do calculations
using voltage and current waveforms stored
in memory, and display the results as
voltage, current, or power trend graphs. This
enables you to perform detailed analyses
on the transient power segments, such as
when a device is powered on or during load
fluctuations.
