Hi all,
this is probably something silly i'm overlooking btu I have a custom built
optical sensor. When I measure across it with an oscilloscope, I get a range
from 0 to 5V.  If I then hook it up to a Ni DAQ card, the computer always
reads it as high... measuring in parallel the range is now only 2 V to 5
V... any idea why it's unable to drive to ground now? thanks a lot
Ben
