I. Overview
HZ-109S3 high-current tester adopts ARM chip to control the output process and large-capacity toroidal transformer, and is equipped with an ammeter displayed on a liquid crystal screen, which simultaneously displays the primary and secondary currents and the transformation ratio. Externally equipped with aluminum alloy chassis and PC panel, it has the characteristics of beautiful appearance, large output capacity, small size and light weight. It is mainly suitable for the occasions requiring high current test such as CT transformation ratio and contact resistance of power system.
