Introduction

The tester can measure the loop resistance at those values and display results in digital. It is high precision and good stability and can meet most power systems' requirements in onsite high-voltage switches maintenance and high-voltage switches factory loop resistance measurement. (It performances accurately and stably)

Features

1. High current switching power supply: using the latest technology, continuous output large current for a long time, overcomes the drawbacks of pulse power supply transient current, breakdown can switch contact film effectively and get good test results;

2. High stability: under severe interference conditions, the last bit of LCD screen data can be stabilized in the range of ±1 word, reading, stability, good repeatability;

3. High precision: the dual high-speed 16 bit Σ-Δ AD sampling, the digital signal processing technology, the highest resolution of 0.01μΩ, is currently the only contact resistance tester can reach 0.01 ohm resolution and very stable, performance more than the imported high current micro ohmmeter;

4. Intelligent: the use of imported high-performance CPU, measuring system according to the size of the signal automatically switch range, to ensure the accuracy of the test of the product. The over temperature circuit can automatically stop the output current when the instrument exceeds the set temperature, so as to ensure the safe use of the instrument;
