Currently, hardware engineers in electronics typically use multimeters to measure parameters such as voltage, current, resistance, and capacitance, or in laboratory environments need to use a desktop digital multimeter.

And then, controlling the measurement port to be communicated with a proper measurement module in each measurement module, so that the electrical parameter value of the data to be measured can be measured, and finally, the electrical parameter value can be displayed to a user.
The parameter pre-analysis module can analyze and identify which kind of parameter (namely specific electrical parameter type) the parameter (namely the data to be measured) accessed to the measurement port belongs to, and further connect the measurement port with the corresponding measurement module according to the analysis and identification result.

As an optional embodiment of the present invention, the "parameter pre-analysis module" may include a "current analysis unit", a "capacitance resonance analysis unit", an "inductance resonance analysis unit", and a "control unit". The current analysis unit is used for detecting whether current passes through the measurement port and whether the current is over-current; the capacitance resonance analysis unit is used for detecting whether capacitance resonance is generated or not when no current flows through the measurement port; the inductive resonance analysis unit is used for detecting whether inductive resonance is generated or not when capacitive resonance is not generated; the "control unit" may be used to turn on or off the "current analysis unit", the "capacitance resonance analysis unit", the "inductance resonance analysis unit", and the "control unit", for example, turning on the "current analysis unit" means that the "control unit" connects the "current analysis unit" with the measurement port; the "control unit" may also be used to control the connection of the measurement port to the measurement module corresponding to the type of electrical parameter, e.g. the "control unit" may control the connection of the measurement port to the voltage measurement module as shown in fig. 2.

and secondly, determining the type of the electrical parameter of the data to be detected by detecting whether the measuring port generates overcurrent or not under the condition that the measuring port has current passing through.
As an alternative embodiment of the present invention, a structure as shown in fig. 3 may be adopted to determine whether a current passes through the measurement port and whether an overcurrent is generated. Specifically, the "current analysis unit" includes a sampling resistor, a differential preamplifier, a post-stage denoising amplifier, an overcurrent detection unit, a control unit, and the like, and whether a current flows through the measurement port can be judged by the "current analysis unit".

Note that, at this time, the input terminal of the "capacitance resonance analysis unit" is connected to the measurement port, and the output terminal thereof is connected to the "control unit". When the circuit of the capacitance resonance analysis unit is connected with a capacitor, a square wave signal can be output, and the control unit can identify the square wave signal.
