| JYR-50C/40C/20C DC Resistance Tester |
JYR (50C) / JYR (40C) / JYR (20C) DC Resistance Tester
Based on JYR (50B), (40B), and (20B), a demagnetization function has been added, extending the DC resistance measurement range to 20kΩ, making it also suitable for DC resistance measurement of high-resistance transformers, mutual inductors, etc., achieving multiple uses in one device.
● Adopts third-generation constant current source technology, with higher efficiency and longer lifespan
● Measurement range increased to 20kΩ, fully enhancing the instrument's application scope
● Charging voltage increased to 30V, faster charging speed
● Equipped with demagnetization function to reduce transformer residual magnetism and avoid closing difficulties
● U-disk data export
● 485 communication interface, can be connected to computer for online operation
● Has anti-breakage and arc protection for inductive test objects
● Has protection against misconnection of AC380V
● Has audible discharge alarm, clear discharge indication
