Changing the Temperature Interval for the Setpoint Clock
Whenever you run a program, there is an interval before the
setpoint temperature is attained. The clock starts counting the
hold time at the beginning of this interval.
For example, if the setpoint temperature is 95 degrees C, and the
temperature interval is 1 degree C, the clock will actually start
counting at 94 degrees C. Figure 7-7 illustrates this example.
Figure 7-7 Diagram of a 1-degree C temperature interval.
The default value for the temperature interval is 1 degree C. The
Configuration function lets you change this value.
CAUTION
Always check this parameter before you start a run.
