The Megger 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.

Operation of the Megger BT51 is simple, there being only one range switch to set. Power is supplied by internal rechargeable cells and the charger unit is incorporated into the case. The instrument is built into a robust, portable case that is weatherproof and shockproof and has a hinged, detachable lid.

The Megger BT51 ductor uses the four-terminal method of measurement. The main advantage of this method is that the resistance of the test leads is not included in the measurement. This is an important factor when the value of the measured resistance is very low. In the diagram, resistance RX is measured only between points A and B; other resistances in the current loop either side of A and B are ignored.

FEATURES:

High test current – 2 a.c. (e.g., for aircraft bond testing).
Four terminal measurement.
Two measuring ranges (2000 mΩ and 20,00 mΩ) and maximum resolution of 0,01 mΩ.
3½-digit LED display, which is helpful in a poorly lit environment.
Protection against 240 V a.c. and warning lights for added safety.
Robust, shockproof, weatherproof, portable case.
Can use very long test leads.
