Low Resistance Testing:
The WR series of test instruments utilize a 4 wire measuring technique for each Channel. The
points where the potential leads are connected determine the resistance reading.
The test set employs a very simple principle of Ohm’s law:
R
=
U
I
R
= Resistance
U
= Voltage
I
= Current
