This is odd. A month ago, I had no problems sourcing current
(4-20mA). Due to a leak developed in my furnace, I haven't been running
my current source for a while. Today, I get everything back together, and
all of a sudden, my AT-AO-10 will not source current. I pulled it out,
checked the fuse (F2), and it was okay. I tried different channels. I
disconnected my loop, and put in a loop that consists of only a 9V battery
and my multimeter, and I still get nothing.
I've done all I know to do. I can't figure out this one for the life or
me. Has anyone ever seen anything like this? If so, can you tell me what
I might try?
FWIW, I am using a CB-50LP to convert my 5o pin ribbon to separate
connectors.
Thanks,
Harry
