Creates channel(s) to measure voltage. If the measurement
        requires the use of internal excitation or you need excitation
        to scale the voltage, use the AI Custom Voltage with Excitation
        instance of this function.

        Args:
            physical_channel (str): Specifies the names of the physical
                channels to use to create virtual channels. The DAQmx
                physical channel constant lists all physical channels on
                devices and modules installed in the system.
            name_to_assign_to_channel (Optional[str]): Specifies a name
                to assign to the virtual channel this function creates.
                If you do not specify a value for this input, NI-DAQmx
                uses the physical channel name as the virtual channel
                name.
            terminal_config (Optional[nidaqmx.constants.TerminalConfiguration]): 
                Specifies the input terminal configuration for the
                channel.
            min_val (Optional[float]): Specifies in **units** the
                minimum value you expect to measure.
            max_val (Optional[float]): Specifies in **units** the
                maximum value you expect to measure.
            units (Optional[nidaqmx.constants.VoltageUnits]): Specifies
                the units to use to return voltage measurements.
            custom_scale_name (Optional[str]): Specifies the name of a
                custom scale for the channel. If you want the channel to
                use a custom scale, specify the name of the custom scale
                to this input and set **units** to
                **FROM_CUSTOM_SCALE**.
