Due to the high current bus bars and terminal connections carry, their junctions are subjected to high amounts of electrical stress, and this can cause the junctions to corrode and weaken. Sometimes the damage isn’t visible and the junction appears to be fine, for that reason it is important to test them to ensure that they are working at maximum efficiency. Regular testing can lead to the early discovery of internal problems, therefore allowing the electrical components to be reconditioned, avoiding future problems.
The Vanguard Auto-Ohm 100 Ampere Micro-Ohmmeter is a reliable tool for testing the reliability of terminal and bus bar junctions. Able to accurately measure resistance from 1 μΩ up to 300 mΩ, the Vanguard Auto-Ohm 100 Ampere Micro-Ohmmeter uses a Kelvin Bridge input to offset the lead resistance. The Vanguard Auto-Ohm 100 Ampere Micro-Ohmmeter can put out test currents ranging from 10 Amperes up to 100 Amperes, and the unit’s internal memory allows for the storage of the 3 most recent measurements as reference.
