Gas graph.
Blue
spike shows where Testo probe filter got accidentally plugged. Flow
rate was down near zero before the filter change. Note the O2
was
reading high at the low flow rate, indicating possibly a slight leak
with the increased vacuum. This leak was an earlier problem that got
resolved with
a workaround (Teflon tape) until new O-rings arrive. It is easy to spot on the gas graph by the characteristic profile.
