The instrument is safe and convenient to operate. It is a fully computerized device with a built-in imported high-performance CPU, ensuring high reliability. After setting the test values according to the interface prompts, there is no need for manual contact with the equipment under test. The instrument automatically completes the test, keeping test personnel away from high-voltage circuits and ensuring their personal safety.

2. With a large output capacity, the maximum output voltage for volt-ampere characteristic tests is up to 1000V, and the maximum current for transformation ratio tests is up to 600A. The instrument's output capacity is 5KVA.

3. Optional accessories include an external voltage booster, an external current booster, and an external voltage regulator. The external voltage booster can increase the voltage up to 2000V, 3A; the external current booster can increase the current up to 1000A; and the external voltage regulator can output up to 1500V, 20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers up to 500KV class 1A.

4. The large 320*240 dot-matrix Chinese character graphic interface clearly displays the volt-ampere characteristic curve after the test, which is clear, aesthetically pleasing, and easy to analyze. It comes with a built-in micro printer for printing curves and test results at any time.

5. The instrument uses a rotary mouse as the input device, making operation convenient and simple with a long service life.

6. The instrument has a built-in Flash memory, so data is not lost after power-off. After on-site tests, results can be viewed and printed indoors.

7. The instrument is equipped with an RS232 communication interface, allowing connection to a computer via a serial cable for PC and instrument communication. Test personnel can use the computer to control the instrument for testing or upload test data from the instrument. The PC application software provided with the instrument is powerful, aesthetically pleasing, and easy to operate, enabling the saving and printing of test results and the export of test data to EXCEL format for editing.

8. The instrument's power supply supports adaptive AC220V and AC380V.
