4.3.5.4. RMS Measurement
The built in RMS measurement measures the EUT voltage and current.
During the surge coupling an ac current is flowing over the coupling capacitor through the surge
wave shape circuit. This current is also measured by the rms meter and is to respect for the EUT
reading.
Additional ac current during surge coupling:
