CPI is suspiciously high
#1
Over the weekend I built up one of Yuriy's mixed-scale kits (nicely done, by the way) and connected a "cheap" digital scale.

In order to get TouchDRO to agree with the scale I wound up with a CPI setting of 400,000.  That seems a bit ridiculous, and in addition it displays an "absolute" value.  That is, it never goes negative from zero.

That indicates to me that I have an offset in the way the (BCD?) data is being interpreted that multiplies the reading and truncates the sign.

So has anyone else seen this kind of behavior, or would someone with a similar scale be so kind as to try setting their CGI to 400,000 and see if they can duplicate it (and then tell me the value that works!)?

I intend to hook up the oscilloscope to determine the protocol and see what the data looks like, but I didn't quite get to it yesterday.

Anyway, is this a great little community or what?  I'm having a lot of fun.
