Hand-held relay verification device and verification method thereof

The invention discloses a handheld relay verification device and a verification method thereof, the handheld relay verification device comprises a device body, and the device body comprises a core control module used for overall operation and coordination control of the whole device; the analog quantity output unit is connected with the core control module and is used for converting the digital quantity signal output by the core control module into an analog quantity signal and outputting the analog quantity signal; and the power supply unit is connected with the core control module and the analog quantity output unit and supplies power to the whole device. According to the invention, alternating current and direct current voltage and current can be output without an external alternating current power supply, and switching value detection can be carried out, so that the verification function of the relay is realized. The portable relay does not need complicated early-stage preparation work before verification
