Discussion of precise voltage measurement

Another LED display wanted...

Yeah, and it's a weirdo too. Each digit is built as two seven-segment displays, so there are two cathode lines and 7 anode lines per char. All the current 7 seg displays have 14 anode lines per char.

I've thought of doing a replacement front panel board (probably using a micro and LCD display), but only one segment is bad and it does not affect the usability of the display... too much work for now.

Is one used as an exponent, and doesn't need all segments to work?
