4.9 Analysis configuration menu
Through this menu the user can configure the available parameters for a proper combustion analysis.
Fuel:
Lets the user select the type of fuel to be used during analysis. This datum can be varied either from this menu
or during the analysis itself.
Measurement units:
Through this submenu the user can modify the units of measurement for all the analysis parameters, depending
on how they are used.
O
Reference:
2
In this mode the user can set the oxygen percentage level to which pollutant emission values detected during
analysis will be referenced.
Automatic analysis:
The user can set analysis mode to either manual or automatic.
In manual mode the user performs the three necessary analysis operations manually. In automatic mode the
cycle duration for each reading must also be set - in this case the instrument will conduct each analysis in the
specified time.
Printing may also be manual or automatic. If "auto" printing is selected, the instrument will automatically print the
analysis report in a predetermined format at the end of the automatic analysis.
If ' auto ' printing is selected also at the end of a tightness test a report will be printed automatically.
Condensation
The burner efficiency figure when condensation takes place is influenced by atmospheric pressure and humidity
of the combustion air. As the atmospheric pressure is hardly precisely known, the operator is asked to enter a
related parameter, i.e. the altitude of the place above the sea level, from which the pressure is then derived
once the dependency from atmospheric conditions is neglected. In calculations the value of 101325 Pa is
assumed as atmospheric pressure at sea level. Further the air relative humidity input is allowed, being this
calculated at the combustion air temperature as measured from the instrument; in case this value is unknow the
operator is recommended to enter 50% for this value.
Alarms:
This submenu allows the user to set and memorise 5 alarms, defining the monitored parameter for each (gas,
pressure, Ta, Tf), the alarm threshold and relative unit of measurement and whether it is a low or high-level
alarm.
Low-level alarms are triggered when the reading drops below the defined threshold, whereas high-level alarms
are triggered when the reading rises above the defined threshold.

When an alarm threshold is crossed, the instrument emits an intermittent audible alarm besides activating a
visible alarm wherein the background of the name of the relative reading will start flashing in the analysis
