Pressing the Hold button will activate the hold function while running a temperature controlled program. While in the hold mode, the parame-
ters for the program in process can be modified. The cycle will continue after pressing the Run button. A change of program parameters
during the hold will not change the original program. The original program parameters are maintained for the next heating cycle.
To make changes to a program while in run mode, press the Hold button and the yellow indicator LED will illuminate, and the Run
button yellow indicator LED will turn off. When in hold, the system will maintain the actual temperature of the hottest thermocouple while the program is
being changed.

ber can be changed; however, if the operation of a segment has already been completed in a program, the change to that segment will not affect the
program function.
S Press the Stop button to end the program.
