A dialog box opens indicating that the NI PXI-4224 is self-calibrating.
6.
When the dialog box closes, the NI PXI-4224 is successfully
self-calibrated.
Note
The NI PXI-4224 also can be self-calibrated programmatically by using
DAQmx
Self Calibrate.vi
in LabVIEW.
The results of an internal calibration are stored in the NI PXI-4224 flash
memory so that the CalDACs are automatically loaded with the newly
calculated calibration constants the next time the NI PXI-4224 is
powered on.
Performing a self-calibration at the operating temperature of your
application will ensure the NI PXI-4224 meets the specifications in
Appendix A,
