ZX78 type DC resistor
Description
A DC resistor is a variable resistance measuring tool. The switches used in resistors have low contact pressure, long lifespan, and low voltage transformation. It can be used for measurement and other experiments in factories, schools, and research institutions, as well as for precise adjustment of resistors and known resistance values in DC circuits, and for whole machine calibration of portable DC single arm bridges and resistance thermometers.
