Converting from LabView 4.0 to 8.5

[Matthew_Kelton]

Why don't you use one of the instrument drivers on this page:

I'm using it.

But my program does not succeed. (It runs, but does not measure correctly.)

Does it mean that I should work on this program written in 4.0 and that convertion from 4.0 to 8.5 does not affect on my work in 8.5?

Thanks,

Christyine.

You need to figure out why the latest driver is not working like you expect. Saying that is does not 'measure correctly' is not really providing much information. How about adding some details.

Hello, Dennis.

I can only say that I'm reading overload (1E+38) on HP3458A for mean value, while my input is 10V, 16Hz.

Standard deviation is allways 0,0000.

Can you measure the correct voltage when you manually setup the instrument? Set a breakpoint and when the VI takes the measurement, pause and go to manual mode. If you have to change some instrument setting to get the right reading, add/modify your code to do that as well. If the program is supposed to be making some setting and it's not, then you will have to isolate the bad VI and troubleshoot it. You might want to use NI-Spy if you suspect one of the VIs is not sending the correct command.

Can You please tell me what should I do if my NI Spy does not load?

I see message attached under.

I have downloaded newest version of NI-DMM (ver.290) and NI-488 (ver.2.6).

I have never seen that message and don't know why it would appear if you just start NI-Spy. NI-DMM is only used with DMM's from NI and you don't even need to have it installed.

Hello, Dennis.

I've got my Capture.spy. Problem, while running NI Spy, was in NI Spy Options -> View Selection (I've included all of them).

I'm attaching You capture and hope You will understand where the error is.

You are getting error 14. Do you not see this in the LabVIEW program? For GPIB, the explanation is 'GPIB bus error'. This is a pretty generic error message. First, try a different GPIB cable and if possible, a different instrument and see if you can detect the instrument and do some basci communication in MAX. If you still get an error on the writes, I would suggest uninstalling all of the NI software (NI-488 and NI-VISA) and installing the latest versions of both. After, make sure to run all of the GPIB diagnostics.

Can someone convert this driver for me? I think it was made in 4.0 and I have 8.5 and 8.6 Thanks!
