Figure 6. Heat Up/Cool Down Cycle Time Table
Approximate cycle times for heat up and cool down are given in the table above.
To find a given transition time from an initial temperature to a second target
temperature follow this procedure: Look for an initial temperature in the left
column. Next, look for the target temperature along the top row. The intersection
of the row and column provides the approximate transition time.
