► “Judgment Conditions (Limit Settings)” in the features guide
This section explains how to perform IEC voltage fluctuation/flicker measurements.
Operating procedures are explained using the following setup methods.
• Procedure Using the Setup Menu (see chapter 1)
Note
• In IEC voltage fluctuation/flicker measurement, there is a limitation on the instrument functions and
measurement functions that can be measured. See the appendix in the
Getting Started Guide
, IM
WT5000-03EN.
• While controlling this instrument with the Harmonic/Flicker Measurement Software, do not release the
instrument’s remote mode and change the instrument’s settings. If you do, the instrument may not be able
to perform voltage fluctuation/flicker measurement in accordance with the IEC standard. If you release the
instrument’s remote mode, close the Harmonic/Flicker Measurement Software.
Procedure Using the Setup Menu
1.
Tap the
Setup
icon (
), or press
MENU
under SETUP.
2.
From the

closes the setup screen.
Setting Measurement Conditions (Measured Settings)
3.
Tap the
Measured Settings
tab. An measurement condition setup screen appears.
Set this to IEC Flicker.
Measured Settings button
Set the measurement mode (Flicker, dmax).
Set the observation period of one
iteration. (00:30 to 15:00, only even
numbers can be specified for seconds)
Set the element under
measurement (1 to 7*).
Set the rated voltage assignment method (Auto, Set).
Set the default rated voltage (0.01V to 999.99V).
Set the edition number of IEC 61000-4-15 (Edition 1.1, Edition 2.0).
Set the edition number of IEC 61000-3-3 (Edition 2.0, Edition 3.0).
Set the frequency (50Hz, 60Hz).
Set the voltage (120V, 230V).
Set the steady-state range
(0.10% to 9.99%).
Set the measurement count
(1 to 99).
* Can be set within the range of the installed input elements.
