Operating Instructions Model 200E Instruction Manual
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.
• Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent and 1
part of sample gas):

EXIT ignores the

ENTR accepts the
new setting.
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 Chapter 7.
