[sdiy] is .05 volts low enough to be 0 volts?

[Jon Darby]

Howdy again,
   I'm trying to figure out what is preventing the volume half of my Paia
Theremax from working and was measing the voltage on pin 1 of the LM339 IC
and got a voltage of .05 volts. Paia said this should read between 1-7 volts
but not 0 or 8.2 volts, which "would indicate trouble in this area" (???).
Pin 2, which is the Pitch equivilent pin on the IC reads a healthy 6.5
volts. Is .05 low enough to be considered 0 volts, or should it be a solid
0.000 on the multimeter? Thanks a ton.
