求翻译：3.Advanced setting: Press he SET key for 3 seconds,and the instrument enter the setting state of inner parameter. The first flashing number E0.0 is the advanced number. For example: if you set the advanced number as 0.5℃, and the heating temperature is 50℃, it means that when it reach the temperature of 49.5℃,the current resource stops providing electricity. And the electric relay begins to release heat. And when the temperature is lower than 49.5℃,the motor begins to work again. The bigger you set the advanced number, the less accurate the temperature control will be.(Attention: the advanced setting is to prevent over heating, and it works only if P is 0 .So the number does not need to change.)是什么意思？
