Configures the auto zero mode of the DMM.
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
The instrument handle that you obtain from the IviDmm Initialize Node. The handle identifies a particular instrument session.
Default: None
The instrument handle that you obtain from the IviDmm Initialize Node. The handle identifies a particular instrument session.
Default: None
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 conditions that occur before this node runs.
