Overview
Handheld transformer DC resistance tester is a creative product, with small volume, handheld type, light weight, convenient to carry with.
The meter is not only suitable for transformer, mutual inductor, reactor and other inductive object's testing, but also suitable for copper bar, wires, switch contacting and other resistivity object's testing. The meter's testing speed is very rapid, and accuracy is high.
Product Feature
1. Powered by lithium battery or 220V AC, fully charged once, can continuously test DC resistance of hundreds of transformers. The testing procedure is simple and quick.
2. Output 6 grades of current, max output is 10A, max output voltage is 25V, can automatically choose current, very convenient.
3. With wide measurement range, high testing accuracy, 500μΩ~50kΩ.
4. Having the resistance temperature conversion function, wireless temperature testing module is optional, test on-site object's temperature in real time, ensure the accuracy of resistance conversion value.
5. Having the function of counter electromotive force protection, wire breakdown protection, power breakdown protection, overheat alarm and many other protective functions.
6. 5.6inches large industrial highlight true color LCD, clear to see even under strong sunlight.
7. Configured with external printer, convenient for data printing.
8. Host reserve or U-disk reserve.
