Anyway, to make the battery holder accommodate a single cell, all we need to do is add a wire
where one of the batteries would be:
Now, let's connect the wires into the digital calipers. To do this, we need to remove the little plastic
door where the coin cell battery goes, and solder the ends of the battery holder where the coin cell
battery is supposed to go. Connect the black wire (negative) to the 'bottom' pad, and the red wire
(positive) to the other metal piece that goes on the side of the coin cell battery, like this:
The battery door doesn't fit anymore, so I just modified it a bit by snipping off a corner so the wires
can exit cleanly. Just snip off a small corner of the battery door as shown below. You want to do this
on the left side, since the other side has a tab that keeps it closed.
