4.8.2. DILUTION RATIO

DIL only appears
if the dilution ratio
option has been

factor.
This is the number by

The dilution ratio is a software option that allows the user to compensate for any dilution
of the sample gas before it enters the sample inlet.
1. The SPAN value entered during calibration is the maximum expected concentration
of the undiluted calibration gas
2. The span gas should be either supplied through the same dilution inlet system as
the sample gas or be supplied at an appropriately lower actual concentration.
For example, with a dilution set to 100, a 1 ppm gas can be used to calibrate a 100
ppm sample gas if the span gas is not routed through the dilution system.
On the other hand, if a 100 ppm span gas is used, it needs to pass through the
same dilution steps as the sample gas.
3. Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent and 1
part of sample gas):
The analyzer will multiply the measured gas concentrations with this dilution factor
and displays the result.

The analyzer multiplies the measured gas concentrations with this dilution factor and
displays the result.
Calibrate the analyzer. Once the above settings have been entered, the instrument needs
to be recalibrated using one of the methods discussed in Section 5.
