MVT 100B series contact resistance meters are a new generation of highly portable, lightweight and easy to use products for measuring resistances of a variety of test objects like Circuit Breakers, Isolators, Disconnectors, Bus-Bars, Joints, and others. They inject current up to 100 A through the device under test and measure the micro-ohm resistances accurately even in noisy switchyard conditions. Thus MVT is an ideal preventive maintenance tool for measuring critical resistances. The MVT 100B series product consists of a touchscreen graphical LCD for displaying the injection current, voltage drop and measured resistance in real-time. It uses Kelvin’s 4-wire principle for current injection and voltage measurement for accurate contact resistance measurements. A thermal printer (only in MVT 100B+) prints the test results immediately after the test is performed along with the date and time stamps.
