JD-1B type ground resistance meter calibration device


JD-1B type ground resistance meter calibrator is a special instrument designed to implement the national calibration regulations of the People's Republic of China JJG336-2004 "Calibration Regulations for Ground Resistance Meters" and is used to calibrate ground resistance meters. It can be used to calibrate JJG336- The 2004 "Calibration Regulations for Ground Resistance Meters" is applicable to various types of analog and digital ground resistance meters currently produced in my country and similar imported instruments. They can also be used as ordinary resistance boxes, with wide adjustment range, easy use, and beautiful appearance. Beautiful and other advantages.
