China Winding Resistance Meter DC Resistant Testing DC Resistance Tester

General introduction
GDZRS series Winding DC resistance tester is optimal designed for measuring three phase winding DC resistance of big capacity transformer. It can test three phase winding DC resistances at the same time.Features
1. For on-load variable transformer, no need to discharge, just adjust tap switch diLCD Module rectly.
2. The measurement time is 1/3 of tradition single phase measurement, that working time and labor iHardware Accessories ntensity is shorten.
3. Big screen LCD display, clear and visual, easy operation.
4. Built-in panel printer and big capacity memory, easy to get printing result and convenient to storage data.
5. Stable data, fast testing and good repeatability, suitable for transformer DC resistanMachine Hardware ce on-site measurement.SpecificationsCurrentSingle phase: 1A 5A 10A 20A 40A
