YKG-5018 High Voltage Switch Tester is the first to adopt CPLD storage drum sampling technology. The Chinese character LCD displays results and can print test curves and parameters. YKG-5018 High Voltage Switch Tester fully considers user convenience. Some models are the first in China to have built-in switch operating power supply and loop resistance tester. One instrument is equivalent to the functions of three instruments. It hasRS232/USBinterface to connect to a computer.
