Description
HDJB-802 Microcomputer Protection Relay Test Set
Introduction
The main control board is DSP + FPGA architecture, 16 bit DAC output, generates high - density sine wave 2000 points each circle to fundamental wave, which greatly improve the wave quality and the accuracy of the test instrument.
Classic Windows XP operating interface, friendly man-machine interface, easy and fast to operate; High-performance embedded industrial control computer and 8.4 inch resolution of 800 × 600 TFT true color display which provides rich visual information, includes the current working condition and all kinds of help information.
The software with self-calibrating function, which avoid to calibrate accuracy by adjusting relays after open the case, greatly improve the stability of the accuracy.
Features
