The HOLD Program
During a HOLD program the temperature of the sample block
(and the sample) is held at one temperature for either a fixed time
interval or an indefinite period. Figures 4-4 and 4-5 show the two
common types of HOLD programs. A HOLD program would
normally be used before or after running a CYCL program. For
example a high temperature (e.g., 94 degrees C) HOLD might be
used before cycling and a low temperature (e.g., 4 degrees C)
HOLD might be used after cycling.
The clock starts when the sample temperature is within one
degree C of the target temperature.
