My application uses a Panel Driver for an hp hp53132a time intervale counter with "statistics on"
and a WAIT SRQ on " averaging complete". Averaging takes a few minutes.
Every thing appears fine until I try to stop or exit the program. I am getting this
"Attempted to unlock this non-locked device" error message and VEEPRO cannot exit it
must be called with the task manager.
The 2 last lines of the IOMonitor capture are
Address ... Source Method Call ..... Return Value
GPIB1::6 Agilent VISA VISA::viUnlock ..... VI_ERROR_SESN_NLOCKED
GPIB1::6 Agilent VISA VISA::viStatusDesc VI_ERROR_SESN_NLOCKED : Specified object is not
locked
I have check the log and it appears that VEEPRO effectively sends an extra unlock request to the instrument
when it stops.
Any idea for solving this issue ?
Thank you.
