ZXP31 Four-Terminal AC/DC Low Resistance Box (English Version)
The ZXP31 Four-Terminal Low Resistance Box is a precision measurement instrument designed for simulating and calibrating low resistance values in both AC and DC environments. Featuring a four-terminal Kelvin connection structure, this device effectively eliminates contact resistance interference, delivering high-precision output within the 0.1μΩ to 2Ω range. Its compact industrial design with anti-vibration housing ensures stable operation in temperatures ranging from -10℃ to +50℃.
Equipped with precision alloy resistance elements manufactured through specialized winding techniques and temperature compensation technology, the unit achieves basic accuracy of ±0.02%. The modular resistance switching system offers 20 standard value ranges with minimum 10μΩ increments, complemented by gold-plated terminals that minimize contact potential. Dual-mode operation supports both DC measurements and 50Hz/60Hz AC applications, with transient current capacity up to 30A for high-current testing requirements.
This device finds extensive application in power system ground resistance testing, precision instrument calibration, and industrial sensor debugging. Laboratory users can employ it as a standard resistance source, while field technicians benefit from rapid verification of current transformers and shunt devices. Specially designed heat dissipation architecture with overload protection ensures operational safety during continuous use.
The user interface incorporates ergonomic rotary switches with clear position indicators, supported by non-slip base design for operational stability. A detachable protective cover prevents accidental switch activation and environmental contamination. Each unit undergoes rigorous aging tests prior to delivery to guarantee optimal performance parameters.
