Using traditional methods to measure the transformer winding and the DC winding resistance of high-power inducting devices is a time-consuming and labor-intensive task. The transformer ohmmeter is specially developed with maximum output current 10A, which solves the problem of low-value resistance measurement, meets the needs for fast measurement of inductive coils DC resistance, improves the measurement accuracy of DC resistance, shortens the measurement time and reduces the testing burden. The ohmmeter also extends the DC resistance measurement range to 1MΩ, which is an ideal device for testing the DC resistance of transformer winding and high-power inductive equipment, such as current and voltage transformer with high resistance.
