SH (Supraharmonische 2 kHz – 9 kHz)

With the SH module, the UMD can measure an extended range of harmonics from 2 kHz to 9 kHz. The so-called supraharmonics of voltage and current are measured measured according to the EN 61000-4-7 ed.2 standard. The spectrum spectrum is divided into 35 frequency bands, each 200 Hz wide. from which the DFT is calculated by default. Activating this module activates the measurement of the 2 - 9 kHz harmonics is activated and visualised in the live data. They are also part of the main archive integrated in the internal integrated in the internal memory.
