Yes. 3 digits ==> 2 digits + "." + 1/10th .

Good thing about this unit is that it's really an LED panel
meter that's programmable. It's not much more than a 16F84, with
3 seven segment LEDs, and an A/D converter, with source code.
It doesn't have a digital output in its standard form, but
could be fairly easily modified. I'll have to find the article
that describes it and see if I can make it more available to
the list (Sept 2000 Silicon Chip).
