Correct current measurement
The measurement is not correct, the reading will be zero,
because the sum of all currents is zero (Kirchhoff's 1st. Law).
However, with this circuit and a sensitive clamp meter (for example,
the UNITEST Leakage Current Clamp Meter CHB 3, Order No.
93481), the leakage current of a machine can be measured.
4.3 Voltage measurements
Do not connect more than 600 V AC or 600 V DC to the
input sockets. Exceeding these values can endanger the
operator, and may result in damage to the instrument.
Before switching to a new function, disconnect the probes
from the UUT.
