August 2005
3-17
CCO 5500
Set the calibration target either to a
known value of the gas concentration
or to zero, and set the desired number
of cycles over which the calibration
factor is determined (a minimum of 30 is recommended). The
calibration should now be run and the display will show a count down
during its execution. When the calibration is complete the new "Cal
Factor" will be displayed for about 5 seconds and the instrument will
exit the calibration routine.
NOTE
The calibration routine must be run during commissioning, otherwise the
instrument will not be able to calculate the true level of gas within the duct.
Do not run the calibration routine unless reasonable conditions exist in
the duct. If it is not the initial calibration, it is recommended that the Cal
Factor is recorded from the parameters option, before the calibration is
run.
To aid configuration, and to record any subsequent changes to the
operating parameters, Table 3-1 lists all of the options available, and
can be used as a record of the operating parameters.
