Section 1:Overview:
HGZX-3Multi-value resistorVariable resistance gauges for multi-purpose high-power resistors. The structure is designed according to the four-terminal resistor definition and transition structure design. Each resistor is an independent component composed of precision wire-wound resistor elements and terminal blocks. The precision wire-wound resistor elements are made of high-quality low-temperature coefficient manganin alloy material, manufactured with inductive winding or fine processing, and subjected to strict processing and aging treatments for long-term high stability. Features include compact structure, ease of use, and multiple resistance values.
Section IIApplication:
HGZX-3Multi-value resistors are widely used in factories, companies, schools, and research institutions for electrical measurements and other tests.
