6.3.1 From Setting the Test Conditions to Printing Reports
From setting the test system to optimizing the test conditions
1.
Set the test conditions of the test system and EUT.
Page 4-24
2.
If the same conditions of a test executed in the past are applied, load
and use the test conditions file.
•
Set the output voltage and frequency of the AC Power Supply to match
the power rating of the EUT.
3.
Turn on the power of the EUT.
4.
Showing the Vf-Observation and Analysis display (Vf-VIEW).
Constant measurement state is entered. The current measured values are displayed in
the display.
When synchronizing with the AC power frequency, the triangular wave in the PLL
icon in the upper part of the display gets still. If the synchronous state is not entered
and the triangular wave in the PLL icon does not gets still, check that the AC power is
correctly output. Check that the plug for the voltage sensing terminal is mounted and
wired to the rear-side VOLTAGE SENSING terminal.
The PLL lock frequency range is 45 Hz to 65 Hz.

Optimizing the current range before starting the test
5.
Select the V/I waveform in the view type.
Maximize the input current by changing the operating conditions of the EUT.
6.
Set a current range.
Select the current range so that the V/I and current waveforms are not saturated. If the
input current state is a short interval at maximum, it becomes difficult to check
whether the current waveforms are saturated. Therefore, Steps 5 and 6 should be
repeated after the current range is selected.
From test start to end

Selecting the display to be observed
7.
Select a view type to be observed.
To observe Pinst (St) (momentary flicker value) real-time waveform, select Pinst (St)
waveform. Some displays cannot be selected until the test ends. Pinst (St) waveforms
are measured only when the d measurement method is Pst Auto.
When Manual is selected, the graph is not updated because measurement is not
performed.
8.
Press the START key.
A confirmation dialog box for the line impedance network is displayed.
•
This product does not directly control the line impedance network. For details on
selecting line impedance, refer to the line impedance network operation manual.
