Program Mode Features
Pressing the “Program1-4” button on the Main Menu will bring up Program Screen. Program
Screen contains and displays information on steps 1 through 4; Program Screen 5-8 does the
same for steps 5 through 8. Pressing the button while in one Program Screen will call up the
other. When a program is running, the system will automatically switch between screens as it
steps through the cycle and will indicate the active step by highlighting the step number.
Figure 13 – Program Screen
Program mode allows the operator to create, store, and implement test programs consisting of as
many as eight steps, each with its own ramp rate and soak time. Where the setpoints are in
degrees Celsius (-85 to 225), the ramp rates are in degrees Celsius per minute (0 to 999) and the
soak time in seconds (0 to 999). To enter the values for a step, highlight the appropriate data field
and use the pop up keypad.
The “Run” button starts the program from the beginning. When pressed, it changes to “Stop”.
The “Stop” button terminates the program. When pressed, it changes to “Run”.
The “Hold” button pauses the program at its current step. When pressed, it changes to “Start”.
The “Start” button resumes the program from the step where it was held (soak counter for that
step resets). When pressed, it changes to “Hold”.
As with the Manual Mode Screen, the DUT temperature will be displayed only while in DUT
control mode. When in nozzle control mode, only the nozzle air temperature will be displayed.
