3. Observe the set temperature in the Set Display
window.
4. To decrease the set temperature, press the
Down Arrow Key.
5. To increase the set temperature, press the Up
Arrow Key.
Ramp and Soak Mode
In Ramp and Soak mode of operation, the oven executes
a sequence of ramps and soaks programmed by the
operator. The controller is capable of providing up to 4
separate ramp/soak programs, each containing up to 24
steps. During a ramp period, the oven temperature is
controlled to increase at a linear rate set by the operator.
During a soak period, the oven maintains a constant tem-
perature for a time interval selected by the operator.
Program Steps
A program consists of a sequence of operations or “steps”
which the oven controller may be set up to perform.
There are 24 program “steps” in each of the 4 available
programs. The programmed operations are executed in
the order entered: step 1, step 2, step 3, etc. A program
may have a maximum of 24 steps, or as few as two (one
must be an End).
Each program may consist of any of the four basic opera-
tions described below, except in step #1, which cannot be
a jump command. The corresponding LED display for
each operation is shown at the left.
A Set Point program step causes the oven set tempera-
ture (shown in the Set Display) to be linearly increased or
decreased (“ramped”) at a selected rate. The StPt opera-
tion begins at the current oven temperature and finishes
at the programmed Set Point temperature.
Soak causes the final set temperature from the preceding
step to be held for a time interval of up to 23 hours, 59
minutes and 59 seconds. This duration may be extended
by adding further Soak steps or using a Jump Loop (see
below).

PERATION
Note
To rapidly increase or decrease the
set temperature
press and hold the
appropriate arrow key. To slowly
increment or decrement the set tem-
perature one degree at a time,
press
and immediately release the arrow
key.
