6. USER SELECTABLE SETTING
The following features are under your control at any time and can be changed as
detailed later in this section.
Time and date Day/ Month order is selectable and the real time clock and
calendar are fully adjustable
.
Fuel type Standard pre-programmed fuels can be selected or users can
define their own fuel characteristics
.
Efficiency Efficiency readings can be selected to be based on Gross or Nett
values.
Language The analyser is programmed with ten languages.
Line Rejection For optimum mains electricity noise rejection a software
filter set for either 50 Hz or 60 Hz. Select 50 Hz in Europe
and 60 Hz in the USA. Check your country's power
frequency.
Gas Scale Normalised or un-normalised ppm or mg/m 3 scalings can be
ppm(n) or mg/m 3 (n) selected. Normalised is also known as referenced readings to
Oxygen. See
Reference Oxygen below.
Compensation Some sensors are cross sensitive to other gases. Where
appropriate sensors are fitted so this cross sensitivity can be
compensated for, improving accuracy. During re-calibration
this compensation must be disabled
.
Temperature scale The analyser is programmed for both Celsius and Fahrenheit
Pressure scale The analyser is programmed for inWG, mBar, cmWG and
kPa.
Reference oxygen Toxic gas measurements can be referenced to defined oxygen
levels.
NOx Calculation Determines the level for calculating NOx. Depends on the
sensors fitted and local authority preferences.
Inlet
temperature The flue temperature probe can be used to measure and
programme the air inlet temperature to the boiler
Oxygen calibration If the analyser is being used for multiple checks over the
working day it is advisable to re-set the oxygen sensor at
regular intervals. This function allows re-set without the need
to repeat the start-up routine
Toxic sensor zero The CO and other optional toxic sensors can be reset to zero if
