I have a P5205 differential probe that has a offset issue when switching the attenuation from 500x to 50x and the overage light doesn't seem to come on or any sound either. I would like to open up this probe up for inspection but I have a question in doing so. From a previous post it is from my assumption the screws are hidden below the front label and in order to get to them I would have to puncture the label? Is it possible to peel the label without damage? Thanks
