• When using the furnace, try not to make contact with the inner cavity of the
furnace during the process of installing a test sample to avoid causing
damage to the furnace cavity.
• Do not open the furnace immediately after a test is completed to avoid
serious injury and prevent damage to the furnace cavity.
• Clean the furnace cavity in a timely manner with a soft brush once a test is
completed in order to prolong the service life of the furnace.
• If the furnace is not used for a long period, preheat the furnace before using
it again. The preheating method is as follows:
1. Increase the temperature to 200°C and maintain that temperature for a
least four hours.
2. Increase the temperature to 400°C and maintain that temperature for a
least four hours.
3. Increase the temperature to 600°C and maintain that temperature for a
least four hours.
