GYKZ-1A DC resistance rapid tester

Update Date：2020/05/25 21:18
Brief Description： The DC resistance test is to measure the DC resistance of the transformer windings. You can check the quality of the welding or connection of the leads, whether there is a short-circuit or open circuit between the windings, and whether the tap switc ...

Product Features：
1. Fast test speed: The maximum output charging current of the DC resistance tester can reach 1A,
which can effectively compensate the current inertia of the large-inductance device during measurement,
accelerate the iron core saturation, thereby shortening the charging time and improving the test speed,
which is faster than traditional Instrument single and double arm bridges are hundreds of times faster
2. High accuracy: In addition to the advanced four-terminal measurement method, the DC resistance
tester also uses advanced constant current power supply technology to keep the charging current of the
inductive load at a relatively stable value and stable anti-inductance ability. The anti-interference ability is
strong, thereby ensuring the measurement accuracy. And the use of imported high-quality components,
high accuracy and repeatability of measurement results
3. Wide measuring range: resistance measuring range is 1μΩ ～ 20kΩ
4. AC / DC dual-use: DC resistance tester with rechargeable battery pack, AC / DC power supply,
portable design, easy to use and carry
