Safety Ohm Meter
The Motwane Model LR 201 is a 3½ digit LCD display & fully portable digital safety-ohm-meter, capable of measuring low resistance with 1 m-ohm resolution. It employs the proven 4-wire (4W) where fixed DC current is applied to DUT and voltage drop across the DUT is measured and displayed as proportional resistance reading. This method is used to eliminate the effect of lead resistance on the accuracy of measurement. It is a highly reliable, powerful performance & heavy duty instrument. It is a direct reading instrument leading to simple, speedy, and accurate measurements.
Applications:
Cables
Components
Relays
PC Boards
