Dennis I just found the readings as received on the first replacement set of 
meters I got from TT . 4/27/2005


They were both 2.380 volts with 1 ma through the meter. Everything read with 
a Fluke DVM 0.1% meter.


Second  set of replacement meters were 2.493 volts at 1 ma . (Took 1.01 ma 
for fullscale ) 12/15/2005

BTW I added a 3.3  volt 1/2 watt zener across the meters (2.7 volts would be 
OK too) so the meter voltage couod not go above 3.3 volts anymore - that 
also damped the meter a bit since the forward diode slopws the decay of the 
meter current .  I juts solderd them across the meter terminals. (watch 
polarity)
