Existing programs can be altered or overwritten by using the
EDIT
function. Please note that changes
made are permanent and the original program is not retained. If the original program is still required,
the
COPY
function should first be used to save the program to a different program space (see Section
5.3.4) and then the copy should be edited.
The program name can be edited or deleted at this stage although it will be saved unchanged if the
enter key is pressed without amending the current entry.
Advanced editing features (adjusting ramp speeds, setting a gradient of annealing temperatures,
changing time/temperature with successive cycles) can be accessed by pressing the
