I'm not the only one who thinks so.
But the conductive surface should be behind. And it can be checked only if someone have this side accessible, not my case.
Electro Fan:
Anyone hear from Marmad? - maybe just on vacation, seems like the longest he hasn't posted on this thread since page 1.

It seems to me that the firmware bug
from page one of this massive thread
" 14) Bus decoding does not decode the full ASCII set. Missing characters:[ . , : ; - _ ! " § $ % & / ( ) = ? ] - everything between square brackets (except spaces).
[FW v.00.01.00.02? / FW v.00.01.00.05 / FW v.01.00.00.03 / FW v.01.01.00.02]"
has now been fixed in fw 00.01.01.00.02
At least in my testing at 9600 baud the DS2072 of mine shows nearly all characters from 32 (dec) to 47 (dec) inclusive in an accurate way.
See attached screen print.
(Test conditions: Arduino, softwareserial library using pin 4 for TX data. I toggled pin 10 to give a good trigger point for the DSO, this is shown in ch2 trace.)
So this is good news, eh?

Very good news, and very good work! Nice work!
Gald to see the characters are there, but a question:
In looking at various publications of ASCII tables they seem to show characters 32-47 in charts like this:
http://www.ascii.cl/
This seems to show a somewhat different list/order for 32-47; maybe Rigol lists them in a different order?
EDIT: - after studying it more closely the order looks fine, I think it's good!
Thanks

Not sure if this bug has been noted yet, but if it is in screensaver mode when you power it down, it will be in screensaver mode as soon as you power it up...
