Product Description

0-5000V 0-10000V High resistance box/Insulation resistance tester calibration device/Megohmmeter detection device

Product introduction
The insulation resistance meter verification device is based on the requirements of the relevant verification items in JJG1005-2019 "Verification Regulations for Electronic Insulation Resistance Meters" and JJG622-1997 "Verification Regulations for Insulation Resistance Meters (megohm meters)". And reference to the power industry standard DL/ T845.1-2004 "Electronic insulation resistance meter" general technical conditions in the design and manufacture of special equipment, used to verify the value error of electronic insulation resistance meter, drop voltage (Ud). With the constant speed device (KDCY3 type) produced by our company, the indicating error, open circuit voltage (Uk), median voltage (Uz), peak voltage (Uf) of the pointer megohm meter can be verified. It has the characteristics of compact structure, stable performance and easy to use. It is used by various industrial and mining, enterprises and institutions to verify all kinds of insulation resistance meter equipment.

Technical index
The insulation resistance meter verification device is mainly used to verify all kinds of insulation resistance meters with rated voltage ≤10kV, and can also be used as a standard instrument in the production and repair of insulation resistance meters. The resistor part can be used separately. The digital meter section can measure DC voltage up to 10000V.
