External Calibration halts on error 200546

[CalLab_Mark]

For sure there are bogus stored temperature values in memory (impossible for the card to actually have measured a 97°C internal temperature) so I have reson to believe the rest of the stored data-including cal constants--are also corrupt.  An External Calibration will overwrite these values with new data IF the program will continue past the error.  Is it possible to ignore the error and let the program continue?

The card in question is a PCI-6052E.  It passes Self Test but fails Self Calibration.  It is completely functional except for a -.1V offset on all analog inputs.

We know about the problem you are encountering and are working on the issue. It would be best to direct all responses and questions on this issue to the original forum post found here: http://forums.ni.com/t5/LabVIEW/Overwrite-corrupt-cal-constants/td-p/2520982  Have a good day.

Any updates for me on this issue?

Are there no readers of this forum who have experienced this problem?  I'm very interested in knowing what the actual cause (and solution) was found to be.

As it has been said on the other forum the problem you are encountering should be processed as an RMA. There are many reasons that portions of the eeprom are locked from being written too, namely that if they were overwritten it could brick the device. This is common for most electronic devices and not anything out of the ordinary.

Please refer to your already open SR's on the matter or continue to post in the main forum so that you can get the most timely responses from the community. Have a great day.

The other topic was a hardware question.  This is an inquiry to the possiblity of modifying a program to ignore the error & continue on.  The card/RMA you refer to isn't the only one I have that halts the cal program (or an external calibration) but otherwise works fine in MAX.

I was hoping it was my software question presented here that you were working on.  Not so?

After reading through the previous posts I may have a suggestion that could work for you. You have mentioned several times that the values are only off by a -.1V. Is this consistent and constant? If the the error is linear could you apply a linear adjustment to the received values post recording? You have stated that the device works in all respects except for this slight calibration. I am sorry that you have had this trouble, other then sending the card in for inspection and testing through the RMA there is nothing else that can be done. I do not believe that somehow bypassing the error that you are receiving will fix the issue but you may be able to calibrate the received data by taking data with a card that is calibrated and the card that is not and developing a calibration table that could be used to adjust the values that are being measured. Other then that or sending the card in for an RMA there is nothing else that I can recommend that you do. Have a good day.

Alex,

I run the calibration department of an accredited ISO17065 testing facility.  Although a post-process band-aid to remove the error is possible, what you suggest can't be done in such an environment.  If the card won't clear calibration it simply can't be used. 

I've explored the RMA avenue and unfortunately there's no such thing as "inspection and testing" available.  I was quoted $600 for the repair and an additional $154 for a report to tell me what was wrong--after the repair.  No diagnosis is available. 

I can tell you what's wrong with this approach for free 🙂

What's the board worth to you/your company?

Seems like the company's paying you a lot more to attempt to repair a card than the $600 to have NatInst do it.  Time is money.

If it's not worth it, mark it as "retired" then stash it in a closet somewhere and be done with it.

What's it worth to your company to revive 5 E-series daq cards?

It might be worth $600 to have it repaired--if repair is even possible.  We've sent cards in but I can't recall a single one that has actually been repaired.  We get them back "unrepairable", no diagnosis, and the suggestion to purchase a new one.  $1000 is a lot to ask for a disposable circuit board.
