This test apparatus has compliance with IEC 61000-3-2 for measuring harmonics and 61000-3-3 for measuring flicker. It is normally used in conjunction with Item 536, Laplace AC1000 and a laptop Item 124, Fujitsu Lifebook loaded with harmonics & flicker software. All harmonics can be read up to the 40th. Facillitates class A, B, C & D evaluation.
Note: The mains is very rarely pure enough to successfully carry out a test, without using a low distortion power source.
