Increase the flow rate and/or length of tubing in order to dilute or
minimize the diffusion of oxygen from the vent back to the analyzer.
Problem:
Inaccurate zero operation (i.e. the user has zeroed the analyzer
accidentally on gas much higher than one would normally use for
zero gas.
Solution:
Turn the analyzer off, then back on again. Press the system key when
prompted by the analyzer "press system for default values". This will
return the analyzer to it's default settings in calibration and zero
values. Now proceed to carefully calibrate and zero the analyzer.
