Use the following procedure to set the CO reading to zero.
1.
Allow sufficient time for the instrument to warm up and stabilize.
2.
Adjust the dilution system of
Figure 4–1
so that zero air alone is
present in the manifold.
Since not all flow controllers have a positive shut off, it might be
necessary to disconnect the CO input line and cap it.
3.
Allow the instrument to sample zero air until a stable reading is
obtained.
4.
From the Home Screen, press Calibration>
Calibrate Background
.
The Target Concentration button will read 0.000. The Calculated
Background button will display the background needed to make the
current CO concentration go to zero.
5.
Press
Calibrate
to set the CO reading to zero and to save the new
background.
