Current measurements
Current measurement is intended for measurement of AC currents (leakage currents, load
currents, noise currents) using the iron current clamps or flex clamps.

7.2 Step voltage, Contact/Touch voltage and Potential
7.2.1 Injection of test current
Before starting the Step voltage, Contact/Touch voltage and Potential measurements the
test current must be injected in the earth with MI 3295S.
