Working conditions requirements

Input voltage 220Vac ± 10 %, rated frequency 50Hz;

The tester should be powered by a power outlet with a protective grounding. If there is a problem with the connection of the protected area, or if the power supply does not have an isolated connection to the ground, the tester can still be used, but we do not guarantee security;

The ambient temperature corresponding to the parameter is 23 °C ± 5 °C;

The guarantee  is  one year after the factory check.

CT and PT detection supportation

Meet the requirements of GB 1207, GB 1208, etc..

All test items can be completed by single machine without additional auxiliary equipment.

With micro-fast printer, can print test results directly on site.

Using intelligent controller, the operation is simple.

Large screen LCD, graphical display interface.

CT / PT(excitation) inflection point values are automatically given according to procedure.

Automatic error curves of 5 % and 10 % are given.

It can save 3000 test data and lose power without losing it.

Supports USB disk transfer data, can be read through the standard PC, and generate detection reports.

Compact and lightweight ≤ 22Kg, very good for field testing.
