Megger BT51 Low Resistance Ohmeters

MEGGER BT51
Low Resistance Ohmmeter

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

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
