Segment
The Hi-Res
TM
sensitivity segment sets an
additional parameter associated with Hi-Res
TM
ramp segments which can be used to adjust the
response of the Hi-Res
TM
temperature control
algorithm. This is sometimes necessary because
of the wide variation in decomposition mecha-
nisms of typical sample materials. This segment
has the following format:
Hi-Res
TM
sensitivity <sens_setting>
where:
<sens_setting> is the Hi-Res
TM
sensitivity
setting (1.0 to 8.0)
example:
Hi-Res
TM
sensitivity 2.0
Hi-Res
TM
sensitivity segments execute immedi-
ately when encountered in a method and simply
set the sensitivity setting to the new value
provided. The last value set is used for all
subsequent Hi-Res
TM
ramps until a new value is
set. If no Hi-Res
TM
sensitivity segment has been
encountered in the method before the execution
of a Hi-Res
TM
ramp segment, then the default
sensitivity (1.0) is used.
The sensitivity setting is a unitless number,
ranging from 1.0 (lowest sensitivity) to 8.0
(highest sensitivity). The setting is used by both
the dynamic rate (positive resolution setting)
