Problems solved by technology

The disadvantages of this fault simulation device are: first, it does not have signal detection capability
The disconnection function can only be realized through the manual toggle switch, and the signal cannot be detected through the device
In order to measure the signal, a temporary transfer line must be used, and the measurement of resistance, frequency, voltage, current and other signals can be realized by connecting a multim
