5.2.13 Clamp current measurement
This function enables the measurement of AC currents in a wide range from 0.1 mA up to
16 A with current clamps. Typical applications are:
- Measuring PE leakage currents through PE conductor in permanently installed
appliances,
- Measuring load currents in permanently installed appliances,
- Measuring differential leakage currents in permanently installed appliances.
