Description
This battery operated digital resistance meter is designed to meas-
ure accurately low resistance from 0.001 ohm to 200 ohms, using
four-terminal measurment network which eliminates errors caused
by test lead resistance.

Some typical applications
Relay . switch and connector contacts . PC-plated through holes .
PC track resistance . Transformer and motor windings . Ring circuit
testing . Earth conductor continuity . Wire-wrapped and solder joints
. RFI sheilding and coil resistance.
In the four-terminal “Kelvin” configuration four wires are used to connect
the circuit under test to the instruments.
One pair of wires carries current generated by the instrument, the other
pair connect to the voltage-measuring circuit.
The current circuit is low impedance, the voltage circuit high impedance.
When connected a current flows through the component or circuit under
test and the voltage drop across the test points is measured.
