DC Resistance Rapid Tester

I. Product Features:

1. Intelligent instrument controlled by microcomputer, can store test results

2. Large screen with backlit Chinese character LCD display, easy operation, clear display, friendly human-machine interaction interface, with clear and sufficient prompts during measurement process and instrument working status

3. Adopts current source linear compensation technology, stable testing, high measurement accuracy, fast speed, improves measurement efficiency, and reduces the work intensity of operators

4. Technically uses "four-terminal" measurement to eliminate measurement errors caused by lead resistance and contact

5. Panel printer can quickly print measurement results (optional)

6. Has overvoltage protection function, can prevent back electromotive force impact

7. Small size, light weight, easy to carry

8. This instrument is suitable for measurement and analysis of inductive, low-resistance values such as various power transformers,transformer windings, and other inductive low-resistance measurements and analysis
