Hi Bill-
It sounds like you are running into calibration errors. One suggestion I can offer is to update your NI-DAQ drivers to at least 6.9.3 and then run the
Online E Series Diagnostic Utility. The results of this test may provide more insight into the problem you're seeing.
I have seen a bit of documentation for this error which basically suggests that your calibration EEPROM may be corrupted. I have spoken with the engineer you spoke with over the phone and she seemed to have a few more suggestions to pass on to you.
If these suggestions are not helpful then the card may need to be sent in for recalibration and repair. Please keep us posted with anything new you find or if you have any additional questions.
Thanks-
