The BT51 Low Resistance Ohmmeter makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The test current is maintained at a nominal 2 A, and as the measurement is ratiometric, the reading is unaffected by any current variations.

Features:

High test current
Four terminal measurement
Two measuring ranges (2000 mO. and 20,00 mO.)and maximum resolution of 0,01 mO.
Protected against inadvertent connection to the mains supply
