Error 85 occurring for 4-digit numerical strings

[Zebulan]

Hello, 

I have a labview program that measures the current vs voltage for a field emission device. The problem that I'm having is I recive the error 85 message whenever my current measurment reaches 4 digits, for example, 1000 uA. I've read that the error 85 means the scan from string function is reciving the wrong type of data, so my question is: how can I modify the scan from string function to accept up to 4 digit numbers? My block diagram is attached. 

Thanks

If you specify '%f' as FORMAT STRING, you need not do any changes.

This error must be because of some string other than numeric is being input to the function. Make sure you put a probe and also be watchful for 'non printable' characters.

AHHHH.  No error handling!!!  You really should be passing your error clusters.

Anyways, you might want to set your format strings to be %f.  The other alternative is to just use the Fract/Exp String to Number function.

Thanks for the reply. I have tried formatting the string with %f and had no success.

Also, what do you mean by "put a probe"? Are you refering to a physical measurement while I conduct my experiment or is this an option in LabView? If it's a physical measurement probe I don't think that's possible since the current I'm measuring has values in the micro amperes range.

Thanks. 

I solved the problem today, turns out I needed to add a string width to my "number to decimal string" functions. 

I appreciate all your help guys!
