Precautions for the use of medium temperature muffle furnace

Pay special attention to the application of the medium temperature muffle furnace:   
      When the box-type resistance furnace is used for the first time or is used again after long-term stop, it is necessary to carry out the heating furnace drying: open the furnace mouth at 20~200℃ to bake for 2-3 hours, and close the door at 200~600℃ for 2-3h.   

      Before the experiment, the temperature controller should be protected from vibration, and the location should not be too close to the electric furnace, so as to avoid overheating to prevent the electronic components from working properly. Set the power switch to "off" when transporting the temperature controller.   

      Before application, adjust the temperature controller to the required working temperature, turn on the startup code to energize the box-type resistance furnace. At this time, the ammeter has readings, and the temperature measured by the temperature controller slowly rises, indicating that the box-type resistance furnace and temperature control The instruments are working at normal values.
