BZ6D(RT600) type DC high-power active resistorDetailed product description：

BZ6D (RT600) type DC high-power active resistor
BZ6D type DC high-power active resistor is a DC high-power standard resistor simulated by electronic circuits using DC current comparator technology, which solves the problem of power limitation of physical resistors. It can be used as a standard for circuit resistance tester and transformer rapid tester, with convenient use and flexible operation. It can also be used as a standard meter for DC high current meters, and when paired with a DC high current source and a digital voltmeter, it can also be used to calibrate the shunt (resistor). It is an ideal testing device. It can also be used as a range extender for QJ55.
