5. Display Functions
6. Graph Display Functions
(1) Wiring Check screen
Function The wiring diagram and voltage/current vectors are displayed for the selected wiring system(s). The
correct range for the wiring system is shown on the vector display, to confirm proper measurement
cable connections.
Start-up mode The Wiring Check screen can be set to always appear upon start-up (Start-Up Screen setting).
Basic settings Selects auto-ranging for voltage and current on each wiring system, and sets each value to its de-
fault. Not available when integration or the Hold function is enabled.
(2) Independent wiring system display mode
Function Displays power and harmonic measurement values for channels 1 to 4.
A composite measurement line pattern is displayed for each system.
DMM Basic, voltage, current, and power measurement parameter screens
Harmonics Bar Graph, List or Vector screen
(3) Display Selections
Function Select to display any 4, 8, 16, or 32 of the basic measurement parameters.
Display layout 4, 8, 16, or 32 parameters, Independently set for each screen
(4) Efficiency and Loss Screen
Function The efficiency and loss obtained by the specified calculation formulas are displayed numerically.
Display layout Three efficiency and three loss values.
(5) Waveform & Noise Screen
Function Voltage and current waveforms sampled at 500 kHz and noise measurements are displayed com-
pressed on one screen.
Trigger Synchronized with the harmonic sync source
Recording length 1000/5000/10000/50000 × All voltage and current channels
Compression ratio 1/1, 1/2, 1/5, 1/10, 1/20, 1/50 (peak-to-peak compression)
Also, peak-to-peak compression enables drawing 500-dot (vertical) screen images
Noise sampling 500 kS/s, 250 kS/s, 100 kS/s, 50 kS/s, 25 kS/s, 10 kS/s (according to compression ratio)
Recording time

250 kS/s 4 ms 20 ms 40 ms 200 ms
100 kS/s 10 ms 50 ms 100 ms 500 ms
50 kS/s 20 ms 100 ms 200 ms 1000 ms
25 kS/s 40 ms 200 ms 400 ms 2000 ms
10 kS/s 100 ms 500 ms 1000 ms 5000 ms
(1) X-Y Plot Screen
Function Select horizontal and vertical axes from the basic measurement items to display on the X-Y graphs.
Dots are plotted at the data update interval, and is not saved.
Drawing data can be cleared.
Horizontal axis 1 data item (gauge display available)
Vertical axis 2 data items (gauge display available)
(2) Trend screen
Function Measured values selected as trend display parameters from all basic measurement parameters
are graphed as a time sequence.
Waveforms are graphed by subjecting data refresh rate data to peak-peak compression based on
the time axis setting. Data is not stored.
Operation Graphing can be started and stopped using the RUN and STOP commands, respectively.
During hold and peak hold operation, the display value is graphed.
Graph data is cleared when a trend display parameter is changed; when a setting related to mea-
sured values, for example the range, is changed; when a setting on the System screen is changed;
or when graphing is restarted after clearing the data or stopping graphing.
Number of graphed parameters Up to 8
Graphed parameters All basic measurement parameters can be selected as trend display parameters.
