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
period of time set by the user. The user can select one of four different cycle
functions. 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.
