Development and application of intelligent verification device for insulation (grounding) resistance meter

The intelligent insulation resistance meter realizes a verification device that can simultaneously verify the insulation resistance meter and ground resistance meter, which can provide the standard resistance value for the verification of insulation resistance meter and ground resistance meter. The automation of the verification device had been achieved by the intelligent insulation resistance meter. The resistance value could be automatically output after inputting the value of resistance by the keyboard, which reduces the time of manually adjusting the knob of resistance value. The original verification record and verification certificate will be generated automatically after verification. The application of wireless communication technology enables the wireless connection of computer, automatic resistance box and printer.
