2. When the temperature rises to the desired temperature, the indicator light is off. At the beginning of the constant temperature, the temperature may continue to rise. This is the effect of residual heat, which will tend to stabilize in about half an hour. In the constant temperature process, the temperature control is automatically controlled by the temperature control in the box, without manual treatment.
3. At a constant temperature, a group of heating switches can be enclosed, leaving only one set of electric heaters to work, so as to avoid excessive power and affect the sensitivity of the constant temperature.
4. The box should be placed indoors.
5. A blade switch of the iron casing shall be installed in the power supply line for the purpose of this box and the casing shall be grounded.
6. Please check the electrical performance of the box before powering on, and should pay attention to whether there is open circuit or leakage.
7. When everything is ready to stop, you can put it into the sample, close the door and unscrew the top exhaust valve. At this point, you can connect the power supply and start working.
8. Do not arbitrarily remove the side door, disturb or change the line. Only when the box fails, the side door can be removed and checked one by one. If there is a major fault, it can be with the factory.
9. This box is a non-explosion-proof drying box, so it has flammable volatiles. Do not put it in the dry box to avoid explosion.
10. Two drying shelves are attached to each drying box. The uniform load of each shelf is 15 kg. Do not over-tighten and overload the test specimens to avoid affecting the convection of hot air. At the same time, the test piece should not be placed on the heat sink on the bottom of the studio to prevent overheating and damage the sample.
