WXZR-10A Transformer DC Resistance Tester

brief introduction:WXZR-10A Transformer DC Resistance Tester
WXZR-10A Transformer DC Resistance Tester

Introduction

When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must. In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, to shorten the measurement time and reducing the workload of testers, our company developed rapid direct current resistance tester. This is designed with new power supply technology and stable performance, fast measurement, compact, easy to use, high accuracy, good data reproducibility. It is an ideal piece of equipment for measuring transformer winding and large power output inductor equipment. 

Features

1.With new power supply technology, rapid measurement, compact, easy to use.
2.Can store max 255 groups test data.
3.Adopting “four-terminal” measurement method in technical, it eliminates the measurement error caused by down-lead resistance and contact.
4.Panel printer can quickly print measurement results.

5.Saved data can be reviewed and printed.
