Today, let's learn about the installation and use of ultra-high temperature muffle furnace:
1. After opening the package, check whether the muffle furnace is intact and whether the accessories are complete. The general muffle furnace does not need special installation, but only needs to be placed flat on the indoor flat ground or shelf. The controller shall avoid vibration and shall not be placed too close to the electric furnace to prevent the internal components from working normally due to overheating.
2. A thermocouple is inserted into the furnace for 20-50mm, and the gap between the hole and the thermocouple is filled with asbestos rope. It is better to use compensation wire (or insulated steel core wire) to connect the thermocouple to the control, pay attention to the positive and negative poles, and do not connect them reversely.
3. Additional power switch shall be installed at the place where the power cord is introduced to control the main power supply. In order to ensure safe operation, the electric furnace and controller must be reliably grounded.
4. Before use, adjust the thermometer indicator to the zero point. When using the compensation wire and cold junction compensator, adjust the mechanical zero point to the reference temperature point of the cold junction compensator. When not using the compensation wire, adjust the mechanical zero point 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. After the wiring is checked and confirmed to be correct, cover the controller housing. Adjust the setting pointer of the temperature indicator to the required operating temperature, and then turn on the power.
Turn on the power switch. At this time, the green light on the temperature indicator is on, the relay starts to work, the furnace is energized, and the ammeter shows the current. With the increase of the internal temperature of the electric furnace, the pointer of the temperature indicating instrument also rises gradually, which indicates that the system works normally. The temperature rise and constant temperature of the electric furnace are respectively indicated by the traffic light of the temperature indicator. The green light indicates the temperature rise and the red light indicates the constant temperature.
