1. Auto sensor cooking
Auto sensor cooking is a revolutionary way to cook by microwave with-
out setting a power level or selecting a time.
All that is necessary is to select an Auto Sensor Program before start-
ing to cook.
Understanding Auto Sensor Cooking
As a food cooks, a certain amount of steam is produced. If the food is
covered, this steam builds up and eventually escapes from the con-
tainer. In Auto Sensor Cooking, a carefully designed instrument, cal-
led the humidity sensor element, senses this escape of steam. Then,
based upon the Auto Sensor Program selected, the unit will automati-
cally 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 (See Fig. 14A)
1) The shaded columns in Fig. 14A indicate when the humidity sensor
heater is on.
2) During the first 30 period there is microwave activity at Pi power.
This period is included to T1 time. During the next 30 second period is
no microwave activity. When calculating the T2 time, by using the for-
mula below, make sure this 30 seconds is subtracted from TO time.
3) T1 time:-:--The total amount of time it takes the microwave oven to
switch to T2 time. During this time one of the Auto Senser programs
will be shown in display.
4) T2 time-----When the steam escapes from the cooking container
placed in the oven, the humidity sensor detects it and the microp-
rocessor calculates 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 50 second period. The
coefficient K is programmed into the microprocessor memory
and they are listed in the following tables along with the P1 and
P2 powers. (See Fig. 14B)
Some examples of calculating the T2 time
Example 1: If the T1 time is measured to be 2 minutes and 40 seconds
and the Auto program selected is COOK 6:
T2=T1i XK
= 2 min. and 40 sec. X 0.1
= 160 sec. X 0.1
= 16 sec.
2. Auto Sensor Reheat
With Auto Sensor Reheat, you can accurately reheat foods in accord-
ance with their current state of preparation. This allows you to set the
oven to reheat either: 1) Room temperature foods, 2) Refrigerated
foods and 3) Frozen foods at their appropriate power levels and times.
Best of all, Auto Sensor automatically does it all at the touch of a
button!
NOTE: The Auto Sensor Reheat process is same as Auto Sensor Cook-
Ing process. (See Fig. 14A)
