WRT Portable 5A 10A 20A 40A Transformer DC Winding Resistance Tester
Introduction:
- WRT Transformer Winding DC Resistance Test Equipment is a high precision new generation product that can replace DC Wheatstone Bridge and double-arm Bridge.
- It adopts the advanced starting power constant current source technology, uses four digit and half LCD display value and three digit and half LCD displays the ambient temperature or test current value, it overcomes the shortcoming that the LED display ambient value reading of other similar product is not convenient to read under the sun, at the same time it has the automatic arc extinguishing function.
- It is an ideal equipment for measuring transformer winding and large power output inductor equipment.
Features:
- WRT Transformer Winding DC Resistance Test Equipment has the advantages of quick speed measuring, high precision, visual display, strong anti-interference capability, small size, economical power consuming, stable and reliable test data, not affected by personal factor.
- It is an ideal device to measure various sensible loaded resistance and low voltage starting contact resistance, line and cable resistance and welded seam interface.
- It is a quickest measuring device to measure the DC resistance of current domestic large inductance equipment such as power transformer. Test speed is over one hundred times quicker than the bridge.
