6.7 TRMS current measurement using clamp current
adapter
This function enables the measurement of AC currents in a wide range from 1 mA up to
25 A. Typical applications are:
Ì
measuring leakage currents through PE conductor in permanently installed
appliances,
Ì
measuring load currents through L or N conductor in permanently installed
appliances,
Ì
measuring leakage currents through parallel current paths, etc.
6.7.1 How to perform TRMS current measurement using clamp
current adapter
In order to measure a true RMS current connect the current clamp to the instrument
CLAMP connector first.
