Analysis:
The Firetron 1000 would normally display analysis type as dry. The conversion to wet
analysis requires information on the % water content of the flue gas. Where the analysis is wet, the
water content in % terms is also displayed.
The formula for wet analysis is as follows:
ppm (wet) = (1 - H
2
O) (ppm) dry
100
where H
2
O = % water content
To change the analysis from wet to dry refer to the Setup menu.

MAKING THE GAS MEASUREMENT
If an attempt is made to make a gas measurement prior to connecting the sample probe, the following
message will be displayed. It will also reflect the settings used the last time the instrument was used.
NOTE: Gas concentration measurements will only be shown for gases where the cell is fitted. To
make a Gas measurement reading press 'GO'.
Example:

Measurement units can be changed. Refer to the Setup menu, Section 3.4.Gas Measurement Display.
The measurement display is shown below. Gas measurements are displayed in their respective units,
i.e ppm or %.
NOTE: This menu will display “O
