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 relay (RY-1) is energized, the
turntable motor, oven lamp and cooling fan motor
are turned on, but the inverter unit is not turned
on.
3. After about 32 seconds, the cook relay (RY-2) 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.

VARIABLE COOKING
When Variable Cooking Power is programmed, the
120 volts A.C. is supplied to the inverter unit which is
operated by the control unit. Microwave power
operation is as follows:
The oven can be set for any of 11 power levels: 0% to
100%(HIGH). The variable cooking power less than
40% is programmed at the ratio of ON time and OFF
time within 32 sec./ cycle time base.

NOTE: The ON/OFF time ratio does not correspond
with the percentage of microwave power, because
approx. 3 seconds are needed for heating of the mag-
netron filament.
SENSOR COOKING CONDITION
Using the Sensor cooking function the food is 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 the 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 input into the LSI.
