Dear all!
I would like  to do an extCAl of PXI-4065 card. I want proceed this acording to calibration procedure but if i perform the NIDMM_CalAdjusrLinearization function with the first step parameters (1 volt range -1 volt) i get a failure: "This calibration step has been performed out of order. Please refer to external calibration procedure for the correct calibration sequence".  I have debug the program step-by-step according to calibration procedure, avrything is correct. What is the right order?
 
My order:
1 INITEXTCAL
2 configure powerline freq.
3 configure number of digit
4 perform ni_dmm control
5 cal adjust_linearization  ----->error?
