SCD and NCD User Manual
However, a new burner (or a burner with a new quartz tube)
can have a very high baseline after first ignition. In this case,
the baseline should gradually decrease, depending on burner
cleanliness. Noise will also greatly decrease over time. For a
well-stabilized system, noise measured by Agilent OpenLAB
CDS should be approximately 4 display units or less.
Checkout can continue before the baseline becomes
completely stable.
