Explanation
For an explanation of the terminology, see section 12.1.
• Measurement Method
Select the voltage fluctuation and flicker measurement method from the two methods below.
• Flicker (normal flicker measurement)
Judges the voltage fluctuation and flicker from dc, dmax, Tmax, and Pst.
• dmax (measurement of dmax caused by manual switching)
You manually turn the EUT switch ON. This instrument measures the voltage
fluctuation caused by the inrush current that flows when the power is turned ON,
and judges the voltage fluctuation and flicker from the dmax average.
• Edition Number of IEC 61000-4-15
You can select the edition number of IEC 61000-4-15.
• Edition 1.1
• Edition 2.0
IEC 61000-4-15 specifies requirements for measurement instruments.
