1、 Preparation work
Before starting to operate this instrument, preparation work needs to be done first.
1. Firstly, turn on the power switch and ensure that the power is functioning properly. Do not attempt to turn on the device when in doubt. Instead, seek professional assistance for inspection and repair.
2. Place the experimental equipment that needs to be heated into a low-temperature constant temperature reaction bath.
3. Set appropriate temperature and time according to experimental requirements, and adjust the thermostat.
2、 Operation process
1. Press the 'Heat' and 'Constant Temperature' buttons to set the operating temperature and duration of the instrument.
2. Open the protective cover of the low-temperature constant temperature reaction bath and observe whether the heating tube is working properly.
3. When the working time is up, you can press the 'Stop Heating' button, and the temperature will slowly decrease until it reaches room temperature.
4. When the temperature drops below 30 ° C, turn off the power switch and remove the experimental equipment.
3、 Precautions
1. Operators should first understand the basic structure and working principle of the instrument to avoid damage caused by misoperation or personal injury caused by improper operation.
2. During the operation, attention should be paid to the working temperature and time of the instrument, and its range should meet the experimental requirements as much as possible.
3. Heating tubes should avoid direct contact with the surface of objects as much as possible to prevent damage to the heating tubes.
4. After use, please immediately turn off the power switch to avoid electrical accidents or energy consumption.
5. Regularly check the fuses and power cords of the instrument to ensure safe operation.
