i am troubleshooting a test set that has, among many other instruments, three Fluke 8846A multimeters being controlled by GPIB. I am running LabVIEW 2009SP1. The canned vis from Fluke threw many errors so i decided to go as simple as possible and send the following commands from a subvi:
:TRIG:DEL:AUTO ON;:TRIG:SOUR IMM; :TRIG:COUN 1; INIT; FETC?
These commands set auto trigger delay on, triggered immediate, set trigger count to 1, sample count to 1, initiate, then got the reading.
i then read 64 bytes back and converted it to a double.
i call this subvi a few hundred times in my main routine. many times i get completely through the main program without issues but occasionally i will get the attached errors (see jpg). this needs to be an automated test set that runs overnight wihtout human intervention. does anyone know a way i can auto-acknowledge these errors to allow the program to run? or better yet, anyone have ideas on why i randomly get this error to begin with??
i have attached my subvi as well.
