MEGGER BT51 Low Resistance Ohmmeter
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.
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.
The instrument has a 31/2 digit LED display to facilitate use in low light levels. Two LED’s on the front panel indicate battery condition and whether test current is flowing when a measurement is being made. A neon lamp indicates the presence of a dangerous voltage if the test spikes are accidentally placed across a live circuit. This warning takes place whether or not the instrument has been switched on.
