how do i calibrate a 6133 using the ddk only?

[AndyRhind2]

Hi:
A customer is using a 6133 and finding a certain amount of drift over the day. He is using the DDK and QNX, he would like to be able to re-calibrate during the day. I see there is a pdf describing the calibration process, however it appears to require LabView etc. This is not an option for him.

Are there any descriptions or examples showing how to calibrate using the DDK?

PS: On the subject of the need to calibrate he says:
To isolate this we have prepared a voltage source plugged straight into the NI box and the calibration differences read a similar offset to what we see with the lasers - we are now fairly confident that the change is internal to the NI.

Hi AndyRhind2,

I would suggest trying calibration through Measurement and Automation Explorer (MAX). MAX allows you to self-calibrate the card (click on the card, and look in the ‘Attributes Tab’ for ‘Self-Calibrate’) or you can setup a task, and calibrate the channels through this task (once the Task is setup, click on the ‘Calibrate’ tab). If you create a task, please make sure to save the task before measuring after calibration or the calibration adjustments will not be applied to the readings.

In order to "calibrate" the 6133, you read the appropriate calibration constants from the EEPROM and then update the onboard calDACs.  Below is an example that shows how to do this for the 6133.  The MHDDK does not provide a mechanism for writing new calibration constants to the EEPROM.  If you want to store new cal constants, you will need to do so in a file and then reference that file in the future.

Can i use this program in zip file for 6143 card as well?
