MilliVolt Drop Test Set 0-100/200..3000Amp. is capable to measure millivolts between 1mV to 2000mV. The instrument can provide test current between 0-100/200..3000Amp subject to the capacity chosen, load resistance and supply voltage. The system uses the four-terminal method - two for current supply and two for measurement. The unit has the high current capability and is of a compact design suitable for testing high current contacts of circuit breakers, switches, busbar joints and other application where high current junctions exist.
