The sensor “senses” the vapor and its resistance increases gradually. When the resistance reaches the value set ac- cording to the menu, supplementary cooking is started.
The time of supplementary cooking is determined by experi- ment with each food category and inputted into the LSI. An example of how sensor works:
1. | Potatoes at room temperature. |

Vapor is emitted very slowly. |

1. | Touch SENSOR COOK pad. |

NOTE: The oven should not be operated on SENSOR COOK immediately after plugging in the unit. Wait two minutes before cooking on SENSOR COOK.
2.Select desired Sensor setting.
3.Touch START pad.
The coil of
4.After about 16 seconds, the cook relay
NOTE: During this first stage, do not open the door or touch STOP/CLEAR pad.
5.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 food, turn it or season, etc.
6.When the timer reaches zero, an audible signal sounds. The
7.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.
COMPU BROIL/ COMPU ROAST/ COMPU BAKE
COMPU BROIL/ ROAST/ BAKE will automatically compute the oven temperature, microwave power and cooking time for baking, roasting and broiling. Set the desired program by touching the COMPU BROIL/ ROAST/ BAKE pad, and number pad. Enter the weight by touching the Number pads. When the START pad is touched, the following operations occur:
1.The COOK indicator will light and the Convection Fan Symbol will rotate.
2.The cooking time will appear on the display and start counting down to zero. The cooking time is adjusted automatically according to the weight of the food.
3.The
4.Now, the oven is in the convection cooking mode.
5.When the oven temperature has reached the programmed convection temperature, the oven goes into the programmed cooking mode.
6.At the end of the COMPU BROIL/ ROAST/ BAKE cycle, the damper is returned to the open position and the oven will go to the off condition. The cooling fan will remain on until the oven has cooled.
COMPU DEFROST COOKING
The COMPU DEFROST key is a special function key to defrost meats and poultry faster and better. COMPU DE- FROST automatically defrosts roast beef, etc.. When the COMPU DEFROST is selected and the food weight is entered by using the COMPU DEFROST pad, the oven will cook according to the special cooking sequence.
FIRE SENSING FEATURE (MICROWAVE MODE)
This model incorporates a sensing feature which will stop the oven's operation if there is a fire in the oven cavity during microwave cooking.
This is accomplished by the LSI repeatedly measuring the voltage across the temperature measurement circuit (ther- mistor) during it's
Operation
Please refer to the timing diagrams below.
1.The thermistor operates within a
2.The above procedure is repeated. If the difference between the first voltage measured (in step 1) and the voltage measured when the procedure is repeated (step
2)is greater than 300mV the LSI makes the judgment that there is a fire in the oven cavity and will switch off the relays to the power transformer, fan motor and convection motor. The LSI also stops counting down and closes the damper door so that no fresh air will enter the oven cavity.
3.Once the fire sensor feature has shut the unit down, the programmed cooking cycle may be resumed by pressing the "START" pad or the unit may be reset by pressing the
"CLEAR" pad.
