Huazheng Factory OEM HZ-3100A 100A Transformer Winding Resistance Tester

The DC Winding resistance is the transformer’s semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project,the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation.

To meet fast measurement requirement, we developed DC Winding Resistance Tester. The instrument is a newpowerful technology, small size, light weight, high output current and other characteristics.

The device is controlled by the single-chip microcomputer , with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.

    Product Features

    1. The whole machine is controlled by high-speed single-chip.

    2. The instrument adopts new power supply technology, with many current gears and wide measuring range, which can be automatically select current according to the load.suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.

    3. The protection function is perfect, can reliably protect the impact of the counter EMF on the instrument, and the performance is more reliable.

    4. With an audible discharge alarm, clear discharge indication, reduce misuse.

    5. Fast response speed.

    6. Intelligent power management technology, the instrument works in the minimum power state, effectively saving energy and reducing heat.

    7. 320X240 dot matrix ultra-small pixel 65K true color LCD,

    8. The instrument comes with a perpetual calendar clock and power-down storage, can store 1000 sets of test data, can be consulted at any time
