Testo Raw Data
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.
