Erratic Readings

Hello all!

I JUST purchased a new DSO Nano V2. I have the latest BenF firmware installed. When I click on ME for measurement, the numbers appear very erratic, not only with no signal, but with a signal attached.

Does anyone have any experience with this?
Could I be doing something wrong?
Do I have a bum unit?

Thanks very much for your time!

It would be more helpful if you can provide a photo.
