Usage of Shanghai Zhengyang QJ57P Resistance Tester

Product highlights:
Measurement range: 0-11111.10 Ω; Minimum resolution: 0.01 цΩ, equipped with AC220V dedicated voltage regulator power supply. Adopting internationally popular and innovative shells.

Application scope:

The QJ57P type is a portable precision DC bridge with a wide range using Kelvin lines. The product is equipped with a zeroing device and can come with a working power supply. Suitable for precise measurement of DC low resistance in laboratories, workshops, or field workplaces of industrial and mining enterprises and research institutions.

*The technical parameters of QJ57P DC double arm bridge are the same as QJ57, and it adopts an internationally popular novel shell.

*Measurement of the resistance value of metal rods, sheets, cables, wires, and other metal conductors.

*Inspection of welding quality for current busbars, metal shells, etc.

*Calibration and adjustment of low resistance standards, DC splitters, power type resistors, etc.

*Measurement of switches, electrical appliances, and contact resistance.

*Measurement of DC resistance and temperature rise test for various types of motors and transformer wire groups.
