at the rate of 2 times per second until the seg-
ment terminates normally or the limit is reached.
If the limit is reached during the execution of a
segment, the remaining portion of the segment is
skipped. Method execution then continues with
the next segment in the method.
The conditions for determining whether limits
have been reached for each type of limit are as
follows:
% - If the condition operator is “<“ and the
sample weight percent is less than or equal
to the limit percent, or if the condition
operator is “>” and the weight percent is
greater than or equal to the limit percent,
then the limit is reached. Values greater
than 100% are permitted to accommodate
weight gains.
%/min -If the condition operator is “<“ and the
derivative of sample weight percent is less
than or equal to the limit percent/minute, or
if the condition operator is “>” and the
derivative of weight percent is greater than
or equal to the limit percent/minute, then
the limit is reached. Negative values
indicateweight gain and positive values
indicate weight loss.
Abort segments are very versatile because they
can be used in front of any method segment
(including other abort segments) to dynamically
change the execution of a method. For example,
an abort segment can be used to control the
switching of a purge gas or activation of an
event relay based on the rate of reaction or the
amount of weight loss. An abort segment in
front of a repeat segment provides a mechanism
to terminate a loop prematurely. Abort segments
