Product Feature And Application

1.The instrument is equipped with an adjustable power output. Whether it is a single-phase or three-phase transformer, with just one wiring, the instrument can complete the measurement, testing and wiring of all winding pairs. The process is simple.

2. In addition to supporting internal power supply testing, it also supports external voltage regulator power supply testing.

3. This instrument adopts a single-phase measurement method. It can automatically calculate the short-circuit impedance, reactance and inductance values of each phase during the three voltage increase processes of a three-phase transformer.

4. The instrument adopts phase-locked loop technology inside to synchronously sample AC signals, ensuring accurate measurement data.

5. This instrument can measure voltage, current, power, frequency, etc.

6. The single-machine measurement range for voltage and current is wide, and it supports external connection of CT and PT to further expand the measurement range.

7. It is equipped with a non-volatile memory that can store measurement data for a long time, and the instrument comes with a built-in printer.

8. It supports USB test data export for further analysis or storage, and also supports USB program updates.

9. Transreflective large-screen LCD, which can display clearly under direct sunlight.
