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

2. It has 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, with an output capacity of 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 of up to 500KV class with 1A current.

4. It features a large 320*240 dot-matrix Chinese character graphical interface. After testing, the volt-ampere characteristic curve can be displayed directly. The graphics are clear and aesthetically pleasing, making analysis easy. 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, which is convenient and simple to operate and has a long service life.

6. The instrument has built-in Flash memory. Data is retained after power-off, and after on-site tests are completed, test 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. It enables saving and printing of test results and allows exporting test data to EXCEL format for editing.

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