V/I Waveform Displays input voltages/current
waveforms. Setting an appropriate current
range.
164
Enlarges and reduces the vertical
and horizontal axes. Measuring the crest factor of a
power supply current waveform of
the EUT.
Displays the values of voltage,
current and frequency by using the
cursor. Obtaining the phase difference of
the current against the voltage.
Sets the current range and checks
the operating conditions of the EUT
by observing waveforms like an
oscilloscope. Enlarging the waveform of the
current at a switching portion.
Monitoring the operating status of
the EUT in real time.
2D Harmonics Displays each of harmonics up to
the fortieth order in bar graphs. Displaying spectral distribution of
harmonics.
165
Enlarges and reduces the vertical
axis (current). Displaying the spectral distribution
of a specific data frame that was
analyzed in the display of
Harmonics Trend.
Displays the value of the current of
a specified harmonic order using
the cursor. Obtaining the margin in relation to a
limit value.
Displays limit values. Making judgment on the spot.
3D Harmonics Displays each of harmonics up to
the fortieth order in bar graphs. Displaying spectral distribution of
harmonics.
166
The bar graph is three-dimensional.
The latest data is displayed in the
remotest area and moves toward
you gradually. Displaying changes in harmonics in
a bird
’ s-eye view.
Enlarges and reduces the vertical
axis (current). Displaying the time transition of the
spectral distribution of harmonics.
Meter Displays measurement items with
two analog meters. Observing changes in measured
values.
166
Retains maximum values
(displayed in red). Obtaining the maximum THC value.
Both the voltage and current
ranges are set to AUTO. Capturing excessive peaks.
Vector Displays input voltages/current
phases in vectors. Obtaining the difference between
each phase.
167
Enlarges and reduces the voltage
and current axes. Continuously observing the
difference between each phase.
Displays the phase difference of
the voltage and current. Obtaining the phase difference of
the current against the voltage.
List Displays selected measurement
items in numeric values. Obtaining the maximum THC value.
168
Obtaining the maximum value of
the apparent power.
Monitoring the operating status of
the EUT in real time.
