Current clamp for AC current
DESCRIPTION
The C173 clamp measures leakage or differential currents from 1 mA upwards
and can also be used with multimeters equipped with a range in mV AC.
The C173 clamp measures earth-loop currents and leakage currents. It also
locates faults in circuits of single and three-phase networks.
For unearthed three-phase systems, use the optional Artifi cial Neutral.
