The instrument is designed to verify the current transformer for instruments below grade 0.02, and the secondary current is 1 ~ 60mA. It is specially designed for the error detection of micro instrument transformers. In the design and production, the anti-interference ability and the operation simplicity have been repeatedly demonstrated, with better technical indicators and stability performance
Overview
Characteristics and Functions
(1) User self-calibration function: the accuracy of the calibrator can be easily adjusted to the technical indicators when leaving the factory through the operation of the panel buttons;
(2) Dynamic synchronous data acquisition technology: it can quickly track the voltage regulator and display the data stably;
(3) Easy to operate;
(4) Ultra-wide working range of current transformer measuring 1%～600%;
(5) With RS232 interface it can be operated online by computer.
