The HZ-B-10A is part of the HZ series DC Resistance Tester, also known as a Transformer DC Resistance Tester, DC Low Resistance Tester, or Ground Bond Tester. It employs microprocessor technology and a precision four-wire measurement method, ensuring accuracy and reliability.

It is primarily used for measuring transformer winding resistance, ground bond resistance, cable conductor resistance, contact resistance of switches, connectors, and relays, riveting resistance of metal joints, coil, motor, and transformer winding resistance, interconnection resistance between metal components, weld joint resistance, parallel connection resistance of batteries, as well as wire length measurement calculations.

The instrument casing features a waterproof protective box, ensuring ruggedness, safety, and durability (protection grade IP65), suitable for outdoor construction sites. It is widely used in building quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, ship and locomotive factories, and more.
