Section 2 Operation

SENSOR COOKING CONDITION

Using the SENSOR COOK function, the foods are cooked
without figuring time, power level or quantity. When the
oven senses enough steam from the food, it relays the
information to its microprocessor which will calculate the
remaining cooking time and power level needed for best
results.
When food is cooked, water vapor is developed. The
sensor "senses" the vapor and its resistance increases
gradually. When the resistance reaches the value set
according to the menu, supplementary cooking is started.
The time of supplementary cooking is determined by
experiment with each food category and inputted into the
LSI.
An example of how the sensor works:
(BAKED POTATOES)
1. Potatoes at room temperature. Vapor is emitted
very slowly.
2. Heat Potatoes. Moisture and humidity is emitted
rapidly. You can smell the aroma as it cooks.
3. Sensor detects moisture and humidity and
calculates cooking time and variable power.

COOKING SEQUENCE

1. Operate the oven in sensor cooking mode by
referring to the operation manual.
NOTE
The oven should not be operated on SENSOR
immediately after plugging in the unit. Wait two minutes
before cooking on SENSOR.
2. The coil of shut-off relays (RY1) are energized, the
oven lamp, stirrer motor and cooling fan motor are
turned on, but the power transformer is not turned
on.
3. After about 32 seconds, the relay (RY2) is energized.
The power transformer is turned on, microwave
energy is produced and first stage is started.
The 32 seconds is the cooling time required to
remove any vapor from the oven cavity and sensor.
NOTE
During this first stage, do not open the door or touch
STOP/CLEAR pad.
4. When the sensor detects the vapor emitted from the
food, the display switches over to the remaining
cooking time and the timer counts down to zero. At
this time, the door may be opened to stir, turn, or
season food.
5. When the timer reaches zero, an audible signal
sounds. The shut-off relay and cook relay are
de-energized and the power transformer, oven lamp,
etc. are turned off.
6. Opening the door or touching the STOP/CLEAR pad,
the time of day will reappear on the display and the
oven will revert to an OFF condition.
