keyword=Left Q1 liquid level meter readback
Earlier today, during the access, Heidi and I re-did the wiring for the
liquid level meter for the Left Q1. Our readback and Cryo's readback were
not even close to each other. By the time we were done we had gone
through a couple of meters and removed a couple of isolation modules. It
was not clear what the original problem had been, but things seemed to be
working correctly by the time we left. Now, the isolation modules for us
and Cryo are in series with the meter. Theirs has a 4-20mA output and
ours has a 0-10V output.
