DILUTION RATIO (OPTION)

DIL only appears
if the dilution ratio
option has been

This is the number by which the
analyzer will multiply the SO
concentrations of the gas passing
through the reaction cell.

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. Once the degree of dilution is known,
add an appropriate scaling factor to the analyzer's SO
the measurement range and concentration values reflect the undiluted values when
shown on the instrument's front panel display screen and reported via the analog and
serial outputs.
Using the Dilution Ratio option is a 4-step process:
1. Select reporting range units: Follow the procedure in Section 5.4.4
2. Select the reporting range mode and set the reporting range upper limit (see Section
5.4).
•
Ensure that the upper span limit entered for the reporting range is the maximum
expected concentration of the undiluted 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):

4. Calibrate the analyzer.
•
Ensure that the calibration span gas is either supplied through the same dilution
system as the sample gas or has an appropriately lower actual concentration.
