Hi;

Some years back we purchased a digital eye chart known as an "Elite Digital Eye Chart" - it is a tiny little thing that outputs to an HDMI port on a TV, and takes power from a USB port on the TV. Very basic but it has been working fine, the Dr was happy with it. We bought it at a Vision Expo show, but I see you can still buy them - even on Alibaba.

Now I need to move it to a different exam room but I can't find the manual and little plastic size gauge that came with it. Does anybody have this and would be able to take exact measurements so I could just make one on paper to use?

Thanks,
