Abstract: A signal processor device comprising: first input means intended to be connected, via a measurement sensor, to a high-voltage signal of an electrical installation; and processor means for analyzing the signal measured by said sensor; the device further comprising: changeover means that are configured to cause the operation of the device to change between a test mode in which the device is disconnected from said high-voltage signal so as to be connected to a test signal, and an operating mode in which the device is disconnected from said test signal so as to be reconnected to said high-voltage signal; and second input means that are connected to said processor means, said processor means being configured to actuate said changeover means so that the device operates in test mode or in operating mode depending on whether the second input means are activated or de-activated respectively.
