12.1 Voltage Fluctuation and Flicker Measurement

Function

This function allows you to perform voltage fluctuation and flicker measurements
conforming to IEC 61000-3-3. If you use the Harmonic/Flicker Measurement Software
sold separately, you can print a report of the measurement judgement results.

• Connecting to the Harmonic/Flicker Measurement Software

For details on connecting this instrument to the Harmonic/Flicker Measurement

Software, see the user’s manual of the Harmonic/Flicker Measurement Software.

When you use the Harmonic/Flicker Measurement Software, this instrument enters

remote mode in which key operations on this instrument are disabled. The settings
described in the subsequent sections are set automatically or set from the setup
screen of the software.

Note

Do not release the remote mode of this instrument and change the settings while operating this
instrument with the Harmonic/Flicker Measurement Software. Doing so may impede voltage
fluctuation and flicker measurements conforming to the IEC standard. If you release the remote
mode of this instrument, close the Harmonic/Flicker Measurement Software.

–

*1  The limit is defined only for 230 V/50 Hz.
*2  The limits varied depending on the EUT.
*3  Tmax for IEC 61000-3-3 Edition 3.0, d(t) for IEC 61000-3-3 Edition 2.0.
  This chapter describes about the example when setting the edition number of IEC61000-3-

3 as Ed3.0. When setting the edition number of IEC61000-3-3 as Ed2.0, please paraphrase

Tmax in this chapter as d(t).

*4 The limits of threshold level is 3.3%.
*5 Cannot be displayed on this instrument screen. The value can be displayed on the screen of

the Harmonic/Flicker Measurement Software.

• Measurement Method

The following two voltage fluctuation and flicker measurement methods are available.

• Normal flicker measurement

Calculates all the values of dc, dmax, Tmax, Pst, and Plt, compares them to the

preset limits, and indicates the total judgement.

• Measurement of dmax caused by manual switching

Measures the maximum relative voltage change, dmax, when the EUT switch is

manually turned ON and OFF, determines the average over 24 measurements, and
compares and judges against the limit.
