    Configures the auto zero mode of the DMM.

    auto zero mode

    Specify the auto-zero mode. The driver sets the IviDmm>Measurement Operation Options>Auto Zero [AZ] property to this value. When the auto-zero mode is enabled, the DMM internally disconnects the input signal and takes a Zero Reading. The DMM then subtracts the Zero Reading from the measurement. This prevents offset voltages present in the instrument's input circuitry from affecting measurement accuracy.

    Defined Values

    IVIDMM_VAL_AUTO_ZERO_ON - Configures the DMM to take a Zero Reading for each measurement. The DMM subtracts the Zero Reading from the value it measures.

    IVIDMM_VAL_AUTO_ZERO_OFF - Disables the auto-zero feature.

    IVIDMM_VAL_AUTO_ZERO_ONCE - Configures the DMM to take a Zero Reading immediately. The DMM then subtracts this Zero Reading from all subsequent values it measures.

    Default: IVIDMM_VAL_AUTO_ZERO_OFF

    instrument handle out

    The instrument handle that you obtain from the IviDmm Initialize Node. The handle identifies a particular instrument session.

    Default: None

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    		If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.
