Page 27: Theory Of Operation
P ER ATI ON Heating When powered, the SGO3 oven chamber heats to and then maintains the currently programmed temperature setpoint. The oven comes from the factory with a temperature setpoint of “OFF”. The setpoint may be adjusted by the end-user using the Set Temperature controls. - Page 28 OPERATION Timed Heating Profile The oven is provided with a Timer subsystem. When set, it runs the oven in a steady-state heating profile at the current temperature setpoint for 1 minute up to 99 hours, 59 minutes. Allow the oven to heat to the profile temperature prior to launching a profile.
