Different degree of temperature at various parts of the cooker during its operation.

TEMPERATURE

After being switch "ON" the operation will be started by generating heat from the heater plate and spread

through the bottom of inner pot. As long as there still be water in the inner pot, the temperature at the bottom will

be always lower than 100 C.

When rice at the bottom is well cooked cause no more water left, then the temperature will sharply raise

up to certain level more than 100 C that the thermostat will automatically switch off the heater plate operation.

(As a whole process, it takes about 30 minutes.)

consecutively after heater plate being switch off. It takes another 15 minutes until rice is completely in the proper

manners.
