I am currently using a rigol dp821 A and I have downloaded the dp 8xx series drivers for labview, on NI max it works perfectly but when I ran a code it spits out a query id fail. I know i can wire a false constant to the initialize block but I think there is another method of seeing the difference between the the query id and what the initialize block is expecting , can anyone tell me how to do that Please elaborate as a I am a novice
