**Operating and Maintenance Guide for Box-Type Resistance Furnace:**
1. The controller of the box-type resistance furnace should be installed in a dry, well-ventilated area free from corrosive gases. The ideal working temperature range is between -10°C and 50°C, with a relative humidity not exceeding 85% to ensure optimal performance and longevity.
2. To maintain accurate measurements, it is recommended to perform an annual check using a DC power source. A difference meter should be used to verify the readings of the XMT-type temperature controller to prevent significant measurement errors that could affect the furnace’s operation.
3. Regularly inspect all wiring connections and the contact points of the AC contactor to ensure they are secure and functioning properly. Any signs of wear or damage should be addressed immediately to avoid potential malfunctions or safety hazards.
4. After each use, always turn off the toggle switch on the control panel first, then disconnect the main power supply. This helps protect the internal components and ensures safe operation during subsequent uses.
Proper maintenance and adherence to these guidelines will help extend the lifespan of your resistance furnace and ensure consistent, reliable performance. Always refer to the manufacturer's manual for specific instructions and safety precautions.
