Good to see you found a solution. :o)
I got stuck with one of those stupid panel
meters myself, one that CAN'T have it's power
rails connected in any way to its gnd or
input. What a crock! It's still in the box,
just about every project i've had where I
needed a 1.99 digit panel meter I couldn't
use the thing. If you send me the circuit you
used i'll put it up. :o)
