I. Main Functions And Features

1.The instrument adopts 7 inch true color liquid crystal, which can measure voltage, current, Angle, power and other electrical parameters, and can display the voltage and current vector diagram, which is clear and intuitive on the same screen.

2. The no-load loss, load loss and other parameters of the transformer can be measured.

3. Can measure single-phase, three-phase transformer impedance, reactance, resistance, impedance voltage percentage and other parameters.

4. The instrument has the function of harmonic analysis, can measure the 1-32 harmonic content of the voltage and current applied on the transformer, and can display the rod diagram and voltage and current waveform diagram.

5. It can automatically record the empty load characteristic curve of different voltage current during the empty load test of transformer, which is convenient for analyzing the characteristics of transformer and iron core.

6. With data storage and data browsing functions, the instrument supports DBF database, which can store test data or browse test records according to user needs. The instrument also supports the USB drive export function, which can export test data through the USB drive, and the database supports the excel spreadsheet open mode, which is convenient for editing, printing or archiving

7. Use 7-inch true color touch screen operation, emwinGUI interface, built-in 128M memory (expandable 4G memory card), support Chinese input, easy to operate.

8. Small size, light weight, accurate measurement, no power failure calendar, clock function, can store the test time at any time.
