between 1440 - 1522, Khoung tried the pinch test again, removing all of the array of tubing. During this test, the overall noise in p\[ref\].11b was significantly less, indicating that part (but not all) of the p' problems still are tubing related. |
At 1525, he sucked on the reservoir and reconnected the (entire) tubing. It appears that the tubing has a leak with a time constant of about 10min. This was actually desirable(!), but indicates that we still have some sleuthing to do.
