How to install the muffle furnace?

After unpacking, check whether the muffle furnace is intact and the accessories are complete.

1. The general muffle furnace does not require special installation. It only needs to be placed flat on a solid cement table or shelf indoors, and there should be no flammable and explosive materials around. The controller should avoid vibration, and the location should not be too close to the electric furnace to prevent internal components from not working properly due to overheating.

2. Insert the thermocouple into the furnace 20-50mm, and fill the gap between the hole and the thermocouple with asbestos rope. It is better to use compensation wire (or insulated steel core wire) to connect the thermocouple to the controller. Pay attention to the positive and negative poles, and do not connect them in reverse.

3. An additional power switch needs to be installed at the lead-in of the power cord to control the total power supply. In order to ensure safe operation, the electric furnace and the controller must be reliably grounded.

4. Before use, adjust the thermostat to the zero point. When using the compensation wire and the cold junction compensator, adjust the mechanical zero point to the reference temperature point of the cold junction compensator. When the compensation wire is not used, the mechanical zero point adjustment To the zero scale position, but the temperature indicated is the temperature difference between the measuring point and the cold junction of the thermocouple.

5. Adjust the set temperature to the required operating temperature, and then turn on the power supply. Turn on the work, the electric furnace is energized, and the input current, voltage, output power and real-time temperature are displayed on the control panel. As the internal temperature of the electric furnace increases, the real-time temperature will also increase. This phenomenon indicates that the system is working normally.
