I'm not absolutely positive, but almost. Take the bettery out and see if
there is continuity between pins 1 and 4 and the battery terminals. I
seem to remember either doing that or actually following the traces on the
board in the scale. Since you may have a different scale you should try
yours and see if it works.

Yeah, if you read that from the file in the files section, it was I who
discovered that. I remember that it's kinda strange, to change modes you
short together the power and clock signals. All of this should be in that
file I mentioned. I think it was under Caliper_Info\Imported_Caliper_Info
or something like that.

Oh. Hmm. Maybe yours is different.

Can you go to:

and see if yours looks anything like the one in the pictures?
