IviPwrMeter Is Zero Correction Complete [ZC]

IviPwrMeterZeroCorrection Capability Group

This VI queries the instrument to determine the status of all zero correction operations initiated by the IviPwrMeter Zero [ZC] or IviPwrMeter Zero All Channels [ZC] VIs. This VI returns the IVIPWRMETER_VAL_ZERO_COMPLETE (1) value in the Status parameter only when zero corrections are complete on all enabled channels.

If some zero correction operations are still in progress on one or more channels, this VI returns the IVIPWRMETER_VAL_ZERO_IN_PROGRESS (0) value. If the driver cannot query the instrument to determine its state, the driver returns the IVIPWRMETER_VAL_ZERO_STATUS_UNKNOWN (-1) value.

Note:

This VI does not check the instrument status. Typically, you call this VI only in a sequence of calls to other low-level driver VIs. The sequence performs one operation. You use the low-level VIs to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviPwrMeter Error-Query VI at the conclusion of the sequence.

	instrument handle The instrument handle that you obtain from the IviPwrMeter Initialize or IviPwrMeter Initialize With Options VIs.
	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 IviPwrMeter Initialize or IviPwrMeter Initialize With Options VIs.
	zero correction status Returns the status of the zero correction. This driver defines the following zero correction status: IVIPWRMETER_VAL_ZERO_COMPLETE (1) - The power meter has completed all zero correction operations. IVIPWRMETER_VAL_ZERO_IN_PROGRESS (0) - The power meter is still performing a zero correction on one or more enabled channels. IVIPWRMETER_VAL_ZERO_STATUS_UNKNOWN (-1) - The power meter cannot determine the status of the zero correction.
	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.
