Adjusting
Resolution Setting
The purpose of the resolution parameter is to
select the range of percent/minute values over
which the heater control system will vary
heating rate in response to changes in the rate of
weight change. In dynamic rate mode (positive
resolution settings) the range of percent/minute
values selected by each resolution setting is
fairly wide (about two orders of magnitude).
This width is adjustable using the sensitivity
parameter.
In constant reaction rate mode (negative resolu-
tion settings) the resolution setting specifies the
percent/minute value that will be used as the
control set point for furnace heating. In this
case the system will adjust heating rate as
required to maintain this constant rate of weight
change. Table B.1 (on the next page) shows the
negative resolution settings and their associated
percent/minute values.
