2 the power supply line connected with the controller and the experimental furnace, the load capacity of the switch and fuse should be slightly greater than the rated power of the experimental furnace.

3 wiring, screw loose controller shell first turn on the left and the right, and then turn on the cover, according to the connected power line. Line and thermocouple controller and electric connecting lines (the best use of the compensation wire). The thermocouple from the hole of the fixed seat in the thermocouple inserted into the furnace, between the hole and the thermoelectric gap with asbestos rope jam, then fixed. (Note: the power phase and line is not reversed, in order to safe operation, the controller and the furnace shall be grounded reliably)

Electricity can be 4 check the wiring is correct, the first switch on and then the toggle switch on the controller panel to the open position, adjust the set button to set the temperature to your desired degree, if you set the switch to the measuring position, the red light (NO), also. Sound contactor, electric power, heating current indicates the current value, with the increase of temperature in the furnace and the temperature rise slowly, working normally. When the required temperature rises to the set, the red light, green light (NO) (YES), electric automatic power-off, stop heating. Later, when the temperature a slight decline in the furnace green light, red light, and automatic electric power. And achieve the automatic control of the temperature in the furnace.

5 for thermocouple protection inspection device is working properly, the method is: loosen one end of the thermocouple, the temperature indicator rose rapidly to the highest point will automatically cut off the heating power, then thermocouple unit was good, reset when the thermocouple can work normally.

6 oven, when the furnace is used for the first time or long-term disabled again after use, must be carried out. The drying process is as follows: when the temperature rises to 200 DEG C for 4 hours (open the door and let the water vapour) when 200 DEG C to 600 DEG C for 4 hours (closed door) when 600 C to 800 C for 2 hours (closed door)
