Features：
The instrument comes with an adjustable power output. Regardless of single-phase or three-phase transformers, only one connection is required, and the instrument can complete the measurement of all winding pairs. The test and connection are simple.
In addition to supporting internal power supply test, it also supports external voltage regulator power supply test.
Meet the test and algorithm specified in "DL/T1093-2008 Guide for Detection and Judgment of Power Transformer Winding Deformation by Reactance Method"
Phase-locked loop technology is used inside the instrument to sample AC signals synchronously, and the measurement data is accurate.
The instrument can measure voltage, current, power, frequency, etc.
The single unit measures voltage and current with a wide range, and supports external CT and PT to further expand the measurement range.
Built-in non-power-off memory, long-term storage of measurement data, the instrument comes with a printer.
Support USB test data export, convenient for further analysis or storage, and support USB program update.
All Chinese menus and operation prompts, the operation is simple and intuitive.
The transflective large-screen LCD can be displayed clearly under direct sunlight.
