ERROR 85

[soufian77]

Je programme une mesure en mode delta en utilisant un pilote de source de courant 6221 et un nanovoltmètre 2182A,

Je reçois cette erreur lorsque j'essaie d'exécuter un programme LabVIEW en mode delta :

Possible reason(s):

Buffer data type is 'NONE', thus
there is no data in buffer.

Complete call chain:
Keithley 622x.lvlib:KE622x -- Read Trace Buffer.vi
delta mode.vi

Je joins à ce message une capture d'écran de l'ensemble du programme et de son erreur et VI.

There error is raised inside this subVI, but most probably originates from your configuration calls before this subVI!

You need to configure your device correctly so it will provide the needed data…

Is there a reason you need all those Unbundle/Bundle operations?

Hi 

Thank you for your responce, i used unbundle/Bundle trying make the subVI (red trace buffer) recognize the in put parameters to solve the isssue but it did not works. 

Could please let me know how how i can configure my device correctly so it will provide the needed data...

Thanks in advance.

It's hard to tell you how to configure your instruments since we don't know what your main goal is.  I suggest that you setup, configure and collect your data manually before you try to automate it with LabVIEW.
