The invention discloses an anti-misoperation universal meter and a using method thereof. The universal meter comprises an anti-misoperation plate, and the anti-misoperation plate is installed on a shell of the universal meter. An anti-misoperation plate protection circuit is arranged on the anti-misoperation plate, and the anti-misoperation board protection circuit comprises a contact monitoring circuit, a meter pen voltage AD conversion circuit, a CPU monitoring circuit, a test circuit, a voice broadcast circuit and an LED indication circuit. The contact monitoring circuit, the meter pen voltage AD conversion circuit, the test circuit, the voice broadcast circuit and the LED indication circuit are connected to the CPU monitoring circuit; the contact monitoring circuit is connected to a universal meter pen jack, a red meter pen and a black meter pen, and the meter pen voltage AD conversion circuit and the test circuit are connected to the red meter pen and the black meter pen. A digital multimeter using the protection circuit can effectively guide a user to correctly use the multimeter, thereby effectively preventing various accidents caused by misoperation, including damage to themultimeter, personal injury and the like.
