<DIV><FONT size=2 face=Arial>I have a 5 volt transducer and I need to
measure the output. The problem I have is the display and transducer both run
off the same power supply (12 volts) but the transducers outputs range is
0.5 to 4.5 volts. The LED meter's input is not free floating. How do I
get the meter ground to be 0.5 volts above the transducer ground. As it is
an LED meter, the current will vary quite considerably with the number of
segments displayed so a simple dropper resister will not do ?
