It can effectively find the manufacturing defects of transformer coil, such as material selection, welding, loose connection parts, lack of strands, broken wires and hidden dangers after operation.Built in large capacity lithium battery, the product is small and easy to carry. The product is not only suitable for the measurement of transformer, transformer, reactor and other inductive test objects, but also suitable for the measurement of copper bar, conductor, switch contact and other resistive test objects. The instrument test speed is fast and the accuracy is high.Features: lithium battery power supply or 220V AC power supply adaptive, one-time charging, can continuously test the DC resistance of hundreds of transformers, the test process is simple and convenient.Output six levels of current, maximum output 10A current, maximum output 25V voltage, and can automatically select current, convenient and fast.Wide range, high precision, 500u Ω ~ 50K Ω.With resistance temperature conversion function.It has many protection functions, such as anti-electromotive force protection, disconnection protection, power-off protection, overheat alarm, etc.5.6-inch super large industrial high brightness color LCD screen, which is still visible in strong sunlight.Equipped with external printer, convenient for data printing.With local storage and USB disk storage.Specifications:Measuring CurrentMeasuring RangeMeasuring CurrentMeasuring Range10A500uΩ ~ 200mΩ 100mA10Ω ~ 200Ω5A10mΩ ~ 1Ω10mA50Ω ~ 2kΩ1A100mΩ ~ 20Ω1mA500Ω ~ 50KΩMeasuring Accuracy±(reading0.2%+2digits)Max.
