Product Features:

1. Meet the 20% -120% regulation point error (angle difference, ratio difference) detection of voltage transformers for
   measurement in compliance with national regulations.

2. Complete the measurement at one time and display (measure according to the regulations) the error of the regulation
  points (angle difference, ratio difference) between the upper limit load and the lower limit load of the voltage transformer.

3. Complete the measurement at one time and display the procedure point error (angle difference, ratio difference) of
  the two sets of actual arbitrary load of the voltage transformer.

4. Detect the transformation ratio and polarity of the voltage transformer.

5. Measure the actual secondary load on site.

6. The instrument can display the test wiring diagram, which is convenient for the operator to check the wiring.

7. The instrument intelligently prompts the wiring error to ensure the safety of the instrument and the accuracy of detection.

8. Adopt the principle of small voltage test to actively protect the safety of the operators.

9. 320 * 240 large-screen LCD display, full Chinese interface. Wiring and operation are simple and easy to carry.

10. Various measurement data can be stored and printed to facilitate user query.

11. The instrument can be used with our company's on-site portable rechargeable test power supply, which is convenient
   for taking power on site.
