Product characteristics

1. Fast testing speed: The maximum output charging current can reach 3A, which can effectively compensate for the current inertia of large inductive devices during measurement, accelerate the saturation of the iron core, shorten the charging time, and improve the testing speed. It is hundreds of times faster than traditional single and double arm bridge instruments
2. High accuracy: In addition to using advanced four terminal measurement method, this instrument also adopts advanced constant current power supply technology to maintain a relatively stable charging current for inductive loads, with stable anti sensing ability and strong anti-interference ability, thereby ensuring measurement accuracy. And using high-quality imported components from abroad, the measurement results have high accuracy and good repeatability
3. Wide measurement range: The resistance measurement range is 1 μ Ω～ 2K Ω, with a wide range
4. Dual use of AC and DC: This DC resistance rapid tester comes with a rechargeable battery pack, powered by AC and DC, and is designed to be portable and easy to use and carry
