keyword=Right Q2 LHe level meter
Looking at the installed meter with a scope it clearly had issues on the
voltage output stage, 60 Hz ripple. We swapped it out. The new meter was
stable on the output and gave us a number we expected. In the true spirit
of experimental physics we quit when we got the number we wanted to see.
Cryo set the PID loop and we will keep an eye on things.
