Do you see the big button where it says "Change measurement range"? Hit that one and click "yes" on the popup window. Now you are ready to calibrate.[/QUOTE

Thank you for taking the time to post the picture, But no i don't see that box and i have the latest software, I guess now the question is why i dont see it, Could this be because i am using an expansion box?
