The AT9600A AC Grounding Resistance Tester is an instrument designed to measure the grounding impedance inside electrical equipment or the grounding impedance between electrical equipment and the grounding grid, with a maximum AC output current of 40A.
The AT9600A AC Grounding Resistance Tester can be widely used for checking the grounding performance of household appliances, transformers, and electrical equipment. The instrument is equipped with a Handler interface (PLC interface) and RS232C, enabling convenient data communication and remote control with a PC to meet automated testing requirements and improve production efficiency.
