the following data must be configured:
Memory: use this submenu to define the memory in which the test data and client details are to be stored.
Fuel: the user will be asked to define the type of fuel used by the plant.
Operator: this is where the name of the test operator can be entered.
Mode: by entering this submenu, the user can determine the analysis mode - manual or automatic.
If automatic mode is chosen, the reading duration of each and every test must be set, besides the printing mode
- manual or automatic. When flue gas analysis begins, the instrument will perform and memorise the three tests
automatically, at the respective intervals set (at least 120 sec. according to UNI 10389-1).

At the end of each test the instrument will emit an audible alarm (one "beep" after the first test, two "beeps" after
the second test and three "beeps" after the third test).
At this point, when all three tests are over, if "Manual Printing" has been chosen the instrument will display the
average of the three tests with the possibility of recalling the individual values.
If desired, the user can then print the relative data (total, complete, etc....). On the contrary, if "Automatic
Printing" was selected, the instrument will print the test data automatically, based on the current print settings,
without displaying the average test values.
Caution: when in automatic mode Draught, Smoke and ambient CO (NO) measurements must be taken
3
before initiating the flue gas analysis.
If, on the other hand, manual analysis mode is chosen, flue gas analysis will proceed manually (please see
relative Flow Chart). In this case the print settings and automatic test duration will not be considered.
At this point manual analysis may commence, first waiting at least two minutes until the displayed values
stabilise: The user can then proceed with data storage, if required, or print the analysis report directly.
The latter will be printed in the format set beforehand.
When all three tests are over, the user can recall the average analysis screen containing all the data necessary
for compiling the maintenance log of the boiler or plant.

4.17.4 End of Analysis
At the end of the combustion analysis, carefully remove the sample probe and remote air temperature probe, if
used, from their relative ducts, taking care not to get burnt.
Switch off the instrument by pressing the On/Off key.
At this point, if the instrument has detected a high concentration of CO and/or NO, a self-cleaning cycle will be

initiated during which the pump will draw fresh outside air until the gas levels drop below acceptable values.
At the end of the cycle (lasting no longer than 3 min.) the instrument will switch itself off automatically.
