I have an AT-AO-10 that I am using to control a few things, most of which
is using the voltage output. I am using a unipolar, external source
setting. However, I can't get my current output to work. A few
questions: Do I need to use an external voltage source, hooked up to the
EXTREF and RGROUND channels, as I have with my voltage source signals? I
know that I must supply a voltage source wired in series with the signal
that is between 7-40 Volts. But, is this my external source, or do I need
two of them. Also, the manual that came with the AT-AO-10 is pretty lousy
in regards to how to wire it. The diagram shows a 250 Ohm load
(floating). What is this? Is this something that I have to put in there,
as well? ANd wh
at does "floating" mean? If this is something that I have
to provide, does it vary with the size of my external voltage source?
I have a 15 Volt source hooked up right now, but I am also using a 24 Volt
source for some other equipment that I can use. Is there an ideal voltage
source that I should use instead?
Sorry for the ignorance. I just can't get this to work, and have very
little background in EE.
Thanks,
Harry
