THD analysis with Hioki DT4261

In this video we will explain just shortly how we can analyze signals with FFT, so we can determine the THD value for voltage or current. What causes high THD? And what problems does it bring in a factory, or you house? Wel then focus on several ways on THD measurement, involving Hioki DT 4261 and CM 4141-50. If we encounter high THD, we will also know how to fight against it. I have personally compared Hioki DT4261 to Chauvin Arnoux 8334 and KMB SMY133. They were all to the point.
