• Four terminal measurement • High test current • Protected against inadvertent connection to the mains supply
• Two measuring ranges (2000 mW. and 20,00 mW.)and maximum resolution of 0,01 mW.
The AVO Megger BT51 is a Low Resistance Ohmmeter that makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The Megger test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The Megger test current is maintained at a nominal 2 A, and as the measurement is ratio-metric, the reading is unaffected by any current variations.
