Main Features:

Human-machine interaction. 320X240-lattice LCD, displaying working state and operation direction in Chinese, which is legible and neat;

Optional 812 CT test frame (with non-through standard current transformer inside);

Able to measure tolerance at all measuring points automatically required by JJG313-94/JJG314-94 without the aid of PC.

Double hardware protection and polarity protection for all operations. In emergency, protection switch can stop present operation.

Withstand voltage expandable without adding hardware.

Connected with PC, able to run data communication and processing software under Windows 95/98, to save, search and print data, to sort out tolerance and to count test plans.

Manual protection in emergency: In case of emergency, pressing protection button will disconnect input of voltage regulator.

Automatic protection for reversed polarity: Matching with HN-2K01B Full Automatic Transformer Tester, if polarity is reversed, voltage regulator will reset automatically, with sound indication and state display.

Monitor of output voltage and current:

Operator can view output voltage and current directly on the controller display.

Communication:

a Able to communicate with PC through serial communication interface, receive control command from PC, thus realize automatic measuring.

b Able to be connected with customers database for data processing.
