What should be paid attention to before starting the electric oven?

1. The electric oven is placed on the dry floor and work surface of the room, and no other fixing device is required.

2. A knife or air switch should be installed in the power supply line, dedicated to the heating oven, and use a wire that is twice the cross-sectional area of ​​the power cord as the ground wire.

3. Before the power is turned on, check the electrical performance of the electric oven first, and pay attention to whether there is an open circuit or leakage.

4. When everything is ready, you can place the sample, close the door, and open the exhaust valve when necessary. The air gap is about 10mm.

5. After the power supply is connected, the heating switch can be turned on, and the electric oven can dial the temperature setting dial to the required working temperature. The electric oven and the water-proof incubator shall set the temperature “setting-measurement” switch to “setting”, adjust the temperature setting knob to the required working temperature, and then set the “setting-measurement” switch to “measurement”, At this time, the temperature inside the box starts to rise, and the green light is on (intelligent or special requirements, the manual is attached).

6. When the temperature rises to the required working temperature, turn green light off, and then fine-tune to the green light, then turn the indicator light alternately at the constant temperature point. At this time, you can fine-tune the knob to the green light to extinguish Make it constant. When the room temperature is stable, the temperature controller can be adjusted slightly to improve the accuracy of the temperature control. Any operating temperature can be selected by this method.

7. When the electric oven is at a constant temperature, the high temperature switch should be turned off, leaving only a group of electric heaters to work to avoid excessive power and affecting the accuracy of the constant temperature. When the operating temperature is less than 150°C, only one set of heaters is required and the high temperature switch should be turned off.

8, after the temperature is reached, according to the needs of the test, for a certain period of time the temperature, in this process, by the temperature controller automatic temperature control without the need to add artificial
