4. Sensor Cooking (NN-S560BFAPH/CPH NN-
S560WFAPH/CPH)
Auto sensor cooking is a revolutionary way to cook by microwave
without setting a power level or selecting a time.
All that is necessary is to select an Auto Sensor Program before starting
to cook.
Understanding Auto Sensor Cooking
As the food cooks, a certain amount of steam is produced. If the food
is covered, this steam builds up and eventually escapes from the
container. In Auto Sensor Cooking, a carefully designed instrument,
called the steam sensor element, senses this escape of steam. Then,
based upon the Auto Sensor Program Selected, the unit will
automatically determine the correct power level and the proper length
of time it will take to cook the food.
NOTE: Auto Sensor Cooking is successful with the foods and
recipes found in the Auto Sensor Cooking Guide. Because
of the vast differences in food composition, items not
mentioned in the Cooking Guide should be prepared in the
microwave oven using power select and time features. Please
consult variable Power Microwave cookbook for procedures.
Explanation of the Auto Sensor Cooking process
1) During the first 10 second period there is no microwave activity,
and when calculating the T2 time by using the formula below make
sure this 10 second is subtracted from the T1 time. In other words T1
time starts at the end of the 10 second period.
2) T1 time... The total amount of time it takes the microwave oven to
switch to T2 time after the 10 second period.
3) T2 time... When the steam escapes from the cooking container placed
in the oven, the steam sensor detects it and the microprocessor cal-
culates the balance of cooking time. This T2 time is then shown in the
display and begins counting down.
Balance of cooking time (T2 time)
The balance of cooking time which is called T2 time, can be calcu-
lated by the following formula.
T2 time (in sec.)=T1 time X K factor
NOTE: Remember, the T1 time starts after the 10 second period.
The coefficient K is programmed Into the mlcroprocessor
memory and they are listed in the following tables along with
the P1 and P2 powers.
NOTE: When "More" or "Less" pad is selected, the K factor varles
resulting In T2 time to be increased or decreased.
Example of calculating the T2 time
Example 1: If the T1 time is measured to be 2 minutes and 40 seconds
after the 10 second period, and the Auto program selected is
Frozen Vegetable:
T2 = T1 X K
=2 min. and 40 sec. X 0.1
=160 sec. X 0.1
=16 sec.
5. Sensor Reheat (NN-S560BFAPH/CPH,NN-S560WF
APH/CPH)
Auto Sensor Reheat is a quick and easy way to reheat refrigerator
and room temperature foods.
Simply press the reheat pad. There is no need to select power level
and cooking time.
NOTE: The Auto Sensor Reheat process is same as Auto Sensor
Cooking process.
