After connecting the power supply, you can turn on two sets of heating switches, and then set the temperature you need by pressing the buttons on the control instrument. The indicator light is on, and at the same time, the blower switch can be turned on to make the blower work.

When the temperature reaches the desired level, the indicator light will turn off. At the beginning of constant temperature, there may be a continued increase in temperature, which is due to the influence of residual heat. This phenomenon will tend to stabilize in about half an hour. During the constant temperature process, automatic temperature control is achieved through the use of an internal temperature controller within the box, eliminating the need for manual management.

3. When maintaining a constant temperature, one set of heating switches can be turned off, leaving only one set of electric heaters working to avoid excessive power and affecting the sensitivity of the constant temperature.

4. The box should be placed at an indoor level.

5. An iron shell knife switch should be installed in the power supply line for this box, and the outer shell should be grounded.

Before powering on, please check the electrical performance of this box and pay attention to whether there is any open circuit or leakage.

7. When everything is ready, the test sample can be placed in. Close the box door and open the top exhaust valve at the same time. At this time, the power can be connected to start working.

8. Do not remove the side door arbitrarily, disturb or change the circuit. Only when the box malfunctions, the side door can be removed and checked one by one according to the circuit.

9. This box is a non explosion proof drying box, so it contains flammable and volatile substances. Do not put it inside the drying box to avoid accidents.

10. Each drying oven is equipped with two sample shelves. The average load per shelf is 15 kilograms. When placing the test sample, do not place it too tightly or overload it to avoid affecting the convection of hot air. At the same time, the test sample cannot be placed on the bottom heat dissipation plate of the studio to prevent overheating and damage to the test sample.
