Selling a great Bridge DC MVU-49 production The USSR. The bridge is designed to measure the resistance at a constant current of 10 to 100000 Ohm ’±0.2 per cent. For radio Amateurs involved measuring devices and precise fit of wire-wound resistor – it is an indispensable device. And to determine the nature and location of the damage in overhead and cable lines.
For those wishing to learn more: the Device provides an opportunity to make the following measurements and tests:1. Resistance measurement at a constant current.
2. The definition of the nature of the damage air or cable line:
a) a ground fault;
b) circuit between the wires.
3. The definition of asymmetry of the wires.

4. The definition of the circuit one wire to the earth:
a) by way of three dimensions;
b) by way of a loop;
b) by way of three wires.
5. The definition of short circuit between wires on the ground.
6. The definition of a short circuit between .wires.
7. The definition of a fault four-wire cable.
8. The definition of open wire overhead lines.
It's also possible:
a) the use of leverage comparing the bridge as a resistance;
b) the internal use of the galvanometer of the bridge separately as zero device.
