Need assistance calibrating a NI 9214 module.

[CFER_STS]

Given that I am creating a new task, shouldn't the contents of the buffer be only those samples defined by the finite acquisition?

Hello CFER_STS

If the acquisition is finite (sample mode on the DAQmx Timing.vi is set to Finite Samples), NI-DAQmx allocates a buffer equal in size to the value of samples per channel. So, for finite acquisition, the Samples Per Channel determines how many samples are read on each channel.

Hi CFER_STS,

I am having the same problem. Did you get it resolved yet?

No, I haven't, but then I've been unable to return to it. Perhaps next week. I'm glad to hear that someone else is having this issue. Can you elaborate on your setup / code?

[CFER_STS]

So I made the code change to explicitly read the desired number of samples versus the contents of the buffer, but that did not change the behaviour.  If NI has successfully tested a calibration using the Fluke 5700A, I would be very appreciative if you could share the code you used.  I am still reading nonsense resistance values out.  Also, two-wire compensation does not seem to be allowed on the calibrator when using resistances of 100 kOhm or greater, which the calibration procedure does not address.  Interestingly, our in-house calibration lab attempted a calibration of the NI 9214 using NI Calibration Executive, and ran into a similar problem.  Has this combination indeed been tested successfully, and if so, what code / VI was used?

Did you ever get any further assitance with this or figure out the error (I know its 5 months later). I am about to perform the same excercise but if it's not possible to do with the Fluke 5730A then I dont want to waste my time.

Thanks.

The final word from NI is that calibrating the NI 9214 is not possible with a Fluke 5700A, leaving us with the option of spending several thousand dollars for a redundant and (generally) less capable calibrator, or contracting out calibration services for these modules. Not what I wanted to hear, but there it is.
