8.4 Ramp and Soak Program
The ramp and soak program feature for the 9150 allows the user to program a
number of set-points, cycle the furnace automatically between the temperatures
at a scan rate set by the user, and hold the furnace at each temperature for a pe-
riod of time set by the user. The user can select one of four different cycle func-
tions. The Ramp and Soak Menu is accessed by pressing “SET” and “UP”
simultaneously.
8.4.1 Program Points
The 9150 contains eight “program points”. Each program point contains a
set-point, scan rate, and soak time. When the unit is in program mode the unit
heats or cools to the current program set-point at the current program scan rate.
Once the program set-point is reached the unit waits for the program soak time
before heating or cooling to the next program set-point. To access the Ramp
and Soak Program Menu press “SET” and “UP” simultaneously.
