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.
