The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the maximum furnace temperature must not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace is best to work below the maximum temperature of 50 ℃, when the furnace wire has a longer life.

4. According to the technical requirements, regularly check whether the wiring of the electric furnace and the controller is in good condition, whether the pointer of the indicator is stuck or stagnated when moving, and use the potentiometer to calibrate the meter due to magnetic steel, demagnetization, wire expansion, and shrapnel Increased error caused by fatigue, balance failure, etc.
