Hi Zia. No schematic, we'll be lucky to get them to tell about which technology is in there.
Yes I have all the other information and will be happy to share it with you privately but not for publication online.
Along with the normal documents came a certificate good for 15% off the first recalibration at IET.
With luck, next weekend we will have an AD2702SD to try. Both these devices squeeze good performance out of a non-oven protected reference and I wanted to investigate that type technology first.
