Humidiprobe not open error

Post by briancr »

I am trying to run the example humidiprobe vi supplied by you on Labview 2011. The vi runs ok the first time that you open it for a PC restart. If i then stop the vi and try to restart it will no longer run and returns Humidiprobe not open error. Can anyone help please.

As discussed on the phone before stopping the vi you will need to flick the toggle switch to Off to close the unit and release the handle. You will find the CloseUnit dll function call in the stacked sequence.

Is it possible for me to open the humidiprobe read one value and then close humidiprobe so i can use in a subvi. I have tried just linking open, get single value and close and it doesnt appear to work.

Those are internal functions and not for general use.

Please can you post your vi and we can take a look for you.

New readings are available every two seconds, so make sure you have these delays built into your vi
