them to be viewed or printed. No measurements are taken once this function has been
activated. This feature gives the following benefits :-
•
Data can be viewed at a particular point in the boiler tuning process.
•
Multiple printouts may be obtained of the same data.
•
Scales can be changed between printouts giving different units. i.e. ppm and mg/m
