The "save" and "set save params" commands (duplicated for backward

this command be sent each time instrument parameters are changed. If
changes are not saved, they will be lost in the event of a power failure.
When interfacing to an instrument via C-link commands, always enter the
concentration values in ppb or μg/m
PPB
background value to 20 ppm, enter 20000 (ppb) as the value for the set
background command.
Convert concentration formats from xxxxE+yy to x.xxxE+yy. The iSeries
uses more standard script than the C-Series by placing only one digit to the
left of the decimal.
