Of course, other position sensors such as laser or distance sensors may be used to sense the position of the shift knob dial 5' to generate a position signal.
The knob position sensing device is electrically connected with the interface 2 ', and the position signal can be transmitted to the interface 2'.
The indicator light 8 'is also electrically connected to the interface 2'.
As shown in fig. 2 and 3:
in the prior art, a circuit board in the form of a board is used, the front appearance of the board is shown in fig. 2, the back appearance of the board is shown in fig. 3, the board has a matrix-shaped jack 100', and the board also has symbols A, B, C, D, 00, 01, 02, 03, and.
The various components 200 'are inserted into the socket 100' and connected by wires to form a circuit.
The dial 5' of the gear knob of the actual multimeter is rotated to different gears, and a stylus of the actual multimeter is used for contacting jacks at different positions of the circuit on the back of the contact plug board to contact the circuit, so that voltage or resistance or current or capacitance data between the two contacts can be displayed on the screen of the multimeter.
The invention does not have a physical plug board, but uses a touch display 20 ', the touch display 20 ' is connected with a computer host, and the computer host can display a virtual circuit board 12 ' with a jack 100 ' on the touch display 20 '.
The invention also comprises a computer host (not shown), which can receive the signals transmitted by the touch display and the equipment 1 'and can also control the touch display and the equipment 1'.
When the intelligent multimeter is used, firstly, the interface 2 'integrating data and power supply is connected with a computer host, then the switch 4' is pressed, at the moment, the display screen 3 'can be lightened, the positive and negative poles of the two meter pens 7' are set, the two meter pens 7 'are also connected with the computer host through the meter pen interfaces 6', and the indicator lamps 8 'on the two meter pens 7' are in a lightening state.
The touch display 20 'is connected with a computer host, the computer host can display a virtual circuit board 12' with a jack 100 'on the touch display 20', and students or teachers operating the computer host can insert virtual components 200 'into the jack 100' and connect the components with wires to form a virtual circuit.
The circuit board 12' is turned over by the computer host, and the visual effect of the front surface or the back surface is the same as that of the real circuit board.
The teacher can also send the designed circuit board 12' to a plurality of touch displays connected with the computer host for students to use through the computer host.
When measuring a three-dimensional virtual simulation circuit or a three-dimensional virtual simulation component with physical properties on a touch display:
the two measured points on the circuit board 12' directly calculate the various electrical parameter values, such as voltage, resistance, current, capacitance, due to the virtual circuit.
For example, the resistance between the measured point 10 ' and the measured point 11 ' on the circuit board 12 ' in fig. 4 is measured, the shift knob dial 5 ' of the intelligent multimeter is first rotated to the appropriate shift of the measuring resistor, which is shown as 20k, and this position signal can be transmitted to the interface 2 ' and then to the computer host.
Then, the pen points of the two pens 7 'touch the measured point 10' and the measured point 11 'on the measured circuit board 12' on the touch display 20 ', respectively, when the pen 7' touches the touch display, it will generate a touch signal, and this touch signal is sent to the computer host through the pen interface 6 'and the interface 2'. The positions touched by the two styluses 7 ' on the touch display 20 ' are also respectively fed back with a position signal to the computer host, the computer host correlates the touch signal fed back by the styluses 7 ' with the position signal touched on the touch display 20 ' through a program, when the styluses 7 ' feed back the touch signal, the position signal touched is fed back on the touch display 20 ', and the condition that the position signal touched on the touch display 20 ' is fed back is effective is judged. Therefore, the positions of the touch display 20 'touched by the two pens 7' are located, and the position signals fed back on the touch display 20 'are ensured to be generated by the touches of the pens 7', so that the touch misjudgment of other objects is avoided.

When the stylus pen 7 'contacts the proper position of the measured point, namely when both stylus pens 7' contact the jack 100 ', the host computer controls the indicator lights 8' on both stylus pens not to be on, which indicates that both stylus pens contact the proper position of the measured object.
For example, two pens 7 'respectively touch a measured point 10' and a measured point 11 'on a measured circuit board 12' on the touch display, the computer starts to calculate the resistance value between the measured point 10 'and the measured point 11' according to a position signal of the gear knob dial 5 'and a circuit formed by the virtual components 200', and sends the calculation result to the display screen 3 ', and then the display screen 3' displays the measured resistance value of 3.8K Ω.
If the dial of the gear knob is not rotated to the gear position corresponding to the object to be measured, the correct measurement result (displaying the other result corresponding to the gear position of the knob calculated from the circuit properties) will not be displayed on the display screen 3'.
In another embodiment:

When the two pens 7 'contact the measured point 13' and the measured point 14 ', respectively, the host computer controls the indicator lights 8' on the two pens not to be on, which indicates that the two pens contact the proper position of the measured object.
The computer starts to calculate the voltage value between the measured point 13 'and the measured point 14' according to the position signal of the gear knob dial 5 'and the circuit formed by the virtual components 200' on the circuit, and sends the calculation result to the display screen 3 ', and then the display screen 3' displays the measured voltage value 6.0 v.
If the dial of the gear knob is not rotated to the gear position corresponding to the object to be measured, the correct measurement result (displaying the other result corresponding to the gear position of the knob calculated from the circuit properties) will not be displayed on the display screen 3'.
