Yogesh Singh Posted January 25, 2017 Report Share Posted January 25, 2017 When I run the main VI (lia vid mono), I get an error in the visa read in both the subvi (reset the monochromator and set wavelength) "VISA: (Hex 0xBFFF0015) Timeout expired before operation completed." But this error occurs only in the FIRST 2,3 ITERATION of the while loop (however the reset subvi runs only once). When I press the continue button (when the error message pops up), then this error does not occur for the rest of the remaining iterations of the while loop and I am able to record the correct values from the lock-in-amplifiers. Also when I run both these SubVi individually I now ( initially running those subVI, I didn't get any error) get the same error. I have attached the command codes for the monochromator and the manual for lock-in amplifier SR830. I would appreciate your help. Thanks in Advance!!!
