VKCR3670 Transformer DC Resistance Tester

1. The tester has two power supply modes: AC 220V and built-in large capacity lithium battery, which can meet the user`s requirement in various sites.

2. Two measurement modes: automatic measurement mode: the test current can be automatically selected according to the load; Manual measurement mode: 7 test current gears can be choose.

3. The maximum output voltage is 24V, the maximum test current is 10A, and the test speed is fast, which can be applied to various transformers andotherresistance measurements.

4. Equip with 5-inch true-color LCD touch screen, which is dual-purpose for measuring and operating with touch screen/press buttons. With built-inprinter, Bluetooth communication, USB interface.

5. With automatic discharge function, with 75° conversion resistance function, which can compensates for the material temperature of the testedobject
