When the

following options:
x Pre-Defined Reflow Profiles. For convenience, you may quickly select a profile stored in
the Control that has been pre-defined for your most common reflow applications.
x Direct Input. You may use the front panel controls to input the parameters for a reflow
application.
Pre-Defined Reflow Profiles

want (1 £ 15) is displayed on the LCD screen.
NOTE:
The PROFILE NUMBER up/down keys are disabled
when any screen other than the graphic screen or data screen
is displayed on the LCD.
2. Set the HEAT/NO HEAT switch to HEAT. The Control is now
ready to use.
