Product Description

HV HIPOT GDZX-78 DC Resistance Box Decade Resistance Box



I. General information

GDZX-78 standard DC resistance box is a multi-value resistor composed of a series of ten-point discs. The resistance value between the two terminals can be changed by changing the position of the switch brush contact, which can easily check the resistors of class 0.02 and DC single-arm bridge. It can also be used for electrical measurement in factories, schools, and scientific research units and for precise adjustment of resistance in DC circuits. The resistor has the advantages of small zero resistance and small resistance variation.
