In the embodiment of the invention, the measuring meter provided by the invention can be provided with a plurality of connecting interfaces, different connecting interfaces are used for connecting different cables, and the plurality of connecting interfaces are arranged on the shell of the measuring meter and are communicated with a circuit arranged in the measuring meter. Preferably, the plurality of connection interfaces may include an audio line connection interface and a power line connection interface. The audio line connection interface may be used to connect audio lines, such as TS cables and TRS cables. The measuring meter is mainly used for detecting the conduction state of the cable, and two connection interfaces are arranged for each connection interface. For example, as for the audio line connection interface, a first audio interface for connecting one end of an audio line and a second audio interface for connecting the other end of the audio line may be provided. Taking the TS cable as an example, if a musician wants to detect the state of the TS cable, one end of the TS cable may be connected to the first audio interface, and at the same time, the other end of the TS cable may be connected to the second audio interface. After the musician is connected, a detection circuit arranged in the measuring meter can detect an input signal generated by the accessed cable and identify the input signal. If the audio cable connected with the measuring meter is a TS cable, the TS cable generates a signal, for example, a first signal, the detection circuit identifies the first signal and classifies the first signal as the signal of the TS cable, the input signal is processed and then sent to the control circuit, and the control circuit confirms the conduction condition of the corresponding cable according to the received input signal. In addition, a plurality of detection circuits may be provided in the meter, and each detection circuit may detect different input signals. If the audio line connected with the measuring meter is a TRS cable, an input signal corresponding to the TRS cable, for example, a second type signal, is generated correspondingly, the detection circuit recognizes and outputs the second type signal to the control circuit, and the control circuit confirms the conduction condition of the TRS cable according to the received input signal.
The power cord connection interface can include first power interface and second power interface, and first power interface is used for connecting the one end of DC cable, and the second power interface is used for connecting the other end of DC cable, and the musician when using, with the DC cable with first power interface and second power interface connection respectively can. Also, detection circuitry within the meter may identify input signals generated by the DC cable, such as a third type of signal. It should be noted that the first audio interface, the second audio interface, the first power interface and the second power interface provided by the present invention may be disposed along a surface of the shell of the effector, and specific setting positions may be adjusted according to actual situations.
In some embodiments, for example, the step S110 may include the following steps:
if the accessed cable is a TS cable, confirming an input signal corresponding to the TS cable as a first type signal;
if the accessed cable is a TRS cable, confirming an input signal corresponding to the TRS cable as a second type signal;
if the accessed cable is a DC cable, the input signal corresponding to the DC cable is confirmed as a third type of signal.
In embodiments of the present invention, the audio input interface of the effector generally supports multiple types of audio lines, such as TS cables and TRS cables, with different audio lines being used to connect different instruments or audio output devices, such as electric guitars, computers, cell phones, and the like. The musician selects a corresponding audio cable according to the musical instrument or the audio output device used by the musician, for example, the musician can select the TS cable, when the musician is in use, one end of the TS cable can be connected with the first audio interface of the effector, the other end of the TS cable is connected with the second audio interface, and when the musician is detected, the input signal corresponding to the TS cable is identified as a first type signal. If the audio line connected with the effector is a TRS cable, the input signal corresponding to the TRS cable is confirmed to be the second type signal, and if the audio line connected with the effector is a DC cable, the input signal corresponding to the DC cable is confirmed to be the third type signal.
S120, according to the type of the input signal, controlling a display screen of the measuring meter to be switched to a display mode matched with the type of the input signal.

Meanwhile, one input signal may correspond to one display mode, and a plurality of input signals correspond to a plurality of display modes. For example, if the input signal is a first type signal, the connected cable is a TS cable, and the display mode corresponding to the first type signal may be that the currently connected cable is a TS cable, so that the user can identify the type of the cable conveniently. If the input signal is the second type signal, the connected cable is a TRS cable, and the display mode corresponding to the second type signal may be that the currently connected cable is a TRS cable. It should be noted that different display modes correspond to different cables, and that all types of cables can be presented on the display screen at the same time, and that when the different display modes are switched, the corresponding cables are in a highlighted state, as shown in fig. 2. In fig. 2, reference numeral 1 is a display screen of a meter, and reference numeral 2 is a switching key of an effector. The display screen comprises a DC cable, a TS cable, a TRS cable and voltage and current. When switching to the corresponding display mode, for example, when switching to the display mode corresponding to the DC CABLE, the DC CABLE in fig. 2 is in a highlighted state.

and if the input signal is the third type signal, controlling the display screen to switch to a third type display mode, wherein the third type display mode is used for displaying the conduction state of the DC cable.
In the embodiment of the invention, the first type of signal corresponds to the first type of display mode, the second type of signal corresponds to the second type of display mode, and the third type of signal corresponds to the third type of display mode. The different display modes are used for displaying the conduction states corresponding to the different cables. For example, if the connected CABLE is a DC CABLE, the corresponding input signal is a third type signal, and the display mode corresponding to the third type signal is a third type display mode, the display mode may be switched to the third type display mode, in fig. 2, the DC CABLE is in a highlighted state, and the on-off state of the DC CABLE, that is, the "v" in fig. 2, is identified as being in a highlighted state.
And S130, displaying the conduction state of the cable corresponding to the input signal on the display screen.
In the embodiment of the invention, when the display mode is switched to the corresponding display mode, the conducting state of the cable corresponding to the display mode can be identified, and the identification mode can be directly through text reminding, for example, if the DC cable is connected, the DC cable can be displayed in a normal state or the DC cable is displayed in a disconnected state. The identification mode may be a symbol, for example, "v" indicates that the cable is in a normal state, "×" indicates that the cable is in an abnormal state, or may be a symbol in which "/" highlight indicates that the cable is in a normal state, and no highlight indicates that the cable is in an abnormal state, and the specific identification mode may be set according to practical situations. Preferably, highlighting by a "v" indicates that the cable is in a normal state, and not highlighting indicates that the cable is in an abnormal state.
In some embodiments, for example, the method for identifying and displaying a line fault may further include the following steps:
if the accessed cable comprises a DC cable and a power cable, confirming the input signal as a fourth type signal;
if the input signal is the fourth type signal, controlling the display screen to switch to a fourth type display mode;
the voltage and current levels required by the effector are displayed in the display screen.
In the embodiment of the invention, the voltage and current required by the effector can be detected besides the conduction state of the cable of the effector. When the effector connects the DC cable and the power cable at the same time, the input signal inputted can be confirmed as the fourth type signal and switched to the fourth type display mode.
