Product Introduction
Active Transformer DC Resistance Tester is specially designed for small and medium-sized transformers. It consists of a constant current power supply and a voltage signal detection part. The test method is simple, stable and reliable. Five-digit liquid crystal display, high measurement accuracy, convenient reading. The output current gear is adjustable, suitable for DC resistance measurement of various small and medium-sized transformers. This machine has a built-in rechargeable battery and can be used when there is no AC power supply.

System Description of Active Transformer DC Resistance Tester
·AC 220V power socket and switch
The switch controls the on/off of the whole machine's working power, but does not control the power cord and charging circuit.
AC 220V power socket, with power fuse, fusing current 2A, connect the power cord, the instrument charges; the instrument works under AC power.
·Reset key
Press this key to put the machine in the initial state.
·Selection key
After reset, press this key to select the output current.
·Measurement key
After selecting the output current, press this key to complete the entire test process under microcomputer control.
