How does a Muffle stove work? How to use and precautions?
After we receive the Muffle furnace, we will start to enter the use phase, so how to use the Muffle furnace? Today we will take a look at its use methods and precautions are what!
First, the correct use of Muffle furnace
1, the fixed socket behind the controller is connected with the high temperature furnace, the plug behind the controller is connected with the 220V AC power supply, the power supply is connected to the male knife switch and fuse box and other devices. The outer layer of the high temperature furnace is connected with the ground wire to ensure safety.
2. Insert the thermocouple into the high temperature furnace, and the two connecting wires of the thermocouple are respectively connected to the red and black terminals on the controller.
3, when in use, turn on the power switch, the red indicator light is on, indicating that the furnace has been energized, the temperature control key is adjusted to the required temperature, you can automatically set the temperature. When the temperature rises until the temperature pointer rises to the constant temperature pointer, the red light goes out, indicating that the work is normal.
4, after the use, as long as the control power switch to the "off" position, the power supply in the furnace is all cut off, while the switch is pulled down, more safe.
Second, the use of Muffle furnace precautions
When you want to change the specified temperature during use, if the temperature changes from high to low, you need to cut off the power supply. When the pyrometer reading drops below the new predetermined reading, you can rotate the control key to move the fixed temperature indicator to the left on the new predetermined temperature reading, and then switch on the power supply. If the temperature changes from low to high, you must twist the control key to move the fixed temperature indicator to the right on the predetermined temperature reading. Let the pyrometer reading continue to rise.
