HGJDB-2 Grounding Resistance Meter Calibration Device

HGJDB-2The grounding resistance meter calibrator is designed to implement the national verification regulations of the People's Republic of ChinaJJG336-2004The Verification Regulations for Grounding Resistance Meters, a specialized instrument used for verifying grounding resistance meters, can be used for verificationJJG336-2004The "Verification Regulations for Grounding Resistance Meters" are applicable to various models of analog and digital grounding resistance meters currently produced in China, as well as imported similar instruments. They can also be used as ordinary resistance boxes, with the advantages of wide adjustment range, convenient use, and beautiful appearance.

Main technical indicators:
