A multi value resistor is a variable resistance measuring tool, and each ten pin disk is composed of a precision wire wound resistor element and a switch as independent components. Precision resistors are connected between various contact points on the switch, and by rotating the brush of the switch to move on each contact point, the position of the brush can be changed. The resistance values corresponding to the readings of each decimal dial can be obtained between the four terminal posts.

The switches used in resistors are enclosed, the brushes do not need to be cleaned, the contact pressure is low, the lifespan is long, and the variation is small. The support is made of high insulation engineering plastic, with good overall insulation performance. The precision wire wound resistor components are made of high-quality enameled manganese copper alloy wire wound without any inductance, and have undergone strict processing to have good long-term stability.

This machine adopts a fully enclosed shell to reduce the influence of external environment on the internal structure, and adopts a four terminal wiring method to reduce the impact of external wiring on resistance error.
