DO30-Z type megger calibration device


DO30-Z series megohmmeter calibration device is designed and manufactured according to the requirements of JJG622-1997 "Insulation Resistance Meter (Megohmmeter) Calibration Regulations". All indicators meet the corresponding requirements in the calibration regulations. It is not only suitable for testing domestic and imported insulation resistance meters (megohmmeters) of various types and specifications and similar instruments, but it can also serve as a DC standard high resistance box, a high input internal resistance DC high voltage meter, and a grounding resistance meter. Instrument drag device is used.
