HuaZheng HZ-3140A Winding Resistance Meter 40A Portable Transformer DC Resistance Tester

Description:
The DC resistance is the transformer’s semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project，the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation. The DC Resistance transformer to meet fast measurement requirement, we developedHZ-3140A DC Resistance Tester. The instrument is a new powerful technology, small size,

light weight, high output current and other characteristics. The device is controlled by the microcontroller, with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct wayto achieve fast transformer measurement.

Features:
The HZ-3140A 40A Transformer DC Resistance Meter offers large output currents with a wide measuring range, compact size, and lightweight design, ensuring simple operation, high test speed, excellent precision, reliable retesting, and strong anti-jamming capability; it features a complete protection circuit with high reliability, a discharge audible alarm for safe operation, and measures resistance from 100 µΩ to 8 Ω with 0.1 µΩ resolution and ±(0.2%+2) accuracy, suitable for use in ambient temperatures of -10℃ to 50℃, up to 85% humidity, and powered by AC 220 V ±10%, 50 Hz.
