IviDmm Configure Auto Zero Mode
IviDmmAutoZero Capability Group [AZ]
This VI configures the auto-zero mode of the DMM.
 |
instrument handle The instrument handle that you obtain from the IviDmm Initialize or IviDmm Initialize With Options VI. |
 |
auto zero mode (Off) Specify the auto-zero mode. The driver sets the IviDmm 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 Value: IVIDMM_VAL_AUTO_ZERO_OFF |

error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviDmm Initialize or IviDmm Initialize With Options VI. |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
