The electric heating mantle is mainly used for heating laboratory liquids in various technical secondary schools, petroleum, chemical, pharmaceutical, environmental protection and other industries. It uses high temperature resistant alkali-free glass fiber as insulating material, and the resistance wire is sealed in the insulating layer, and then Woven into a hemispherical internal heat heater. This product has the advantages of large heating area, fast heating, good heat preservation effect, no open flame, and not easy to damage glassware.
1. Turn on the power, turn on the power switch, and the upper row of the instrument will display the temperature of the working room. The lower display shows the set temperature. Then press the SET button, the data on the lower row of digital tubes flashes (the upper row is for normal temperature measurement), indicating that the meter enters the temperature setting state, press ▲ or ▼ to set the desired temperature, and then press the SET button to save the set value. At this time, the temperature rise starts, and the indicator light flickers on and off. When the displayed value is basically consistent with the set value, it enters the constant temperature state.
2. Instrument self-tuning function:
Press the SET key for 5 seconds to enter the inner menu of the meter, select the parameter AT and cooperate with ▲ or ▼ to set 1 to start the self-tuning, at this time the AT indicator light starts to flash and the meter enters the self-tuning state. Set the PID parameters that can overcome overheating. During the self-tuning process, press the ▼ key for 5 seconds and then the AT light will go out, the self-tuning will stop, and the instrument will be controlled according to the original PID parameters.
3. Sensor error correction:
When confirming that the value displayed by the instrument is not the correct measured value, the displayed value can be corrected. Press the SET key for 5 seconds to enter the inner menu of the instrument, select the parameter SC and use the ▲ or ▼ key to modify this parameter. The correction range of the sensor error is +50°C to -50°C, after correction, press the SET key for 5 seconds to exit.
