Electric drying oven, electric constant temperature drying oven, constant temperature drying oven before use:
1. Before powering on, first check the electrical performance of the electrical box, and pay attention to whether there is an open circuit or leakage.
2. When everything is ready, put the sample into the sample, close the door, and unscrew the exhaust valve at the same time. The gap is about 10m/m. At this point, you can connect the power supply and start working.
3, electric drying oven, electric constant temperature drying oven, the constant temperature drying box can turn off the high temperature switch when the temperature is constant, leaving only one set of electric heaters work. Reduce power usage while extending relay life.
4. Do not arbitrarily remove the side door, disturb or change the line. Only remove the side door when the box fails, and check the line one by one to check with the factory if there is a major fault.
5. An air switch that matches the current of the equipment should be installed in the power supply line for the purpose of this box, and the conductor is twice as thick as the power line.
6. When the user uses the box, please read the instrument manual at the same time.
7. Electric heating constant temperature drying box use method: The model of the drying oven temperature control instrument with different models is different. Confirm the temperature controller model before use. Intelligent PID temperature control temperature control instrument, instructions for use refer to the dedicated instruction manual. The ordinary digital display temperature controller, the preset value of the temperature, is investigated by the setting circuit setter (knob). The display shows whether the current temperature measurement value or the set value is measured. It is determined by the setting selection switch state. When the button is pressed, the set value is displayed. The preset knob is clockwise and adjusted to the preset value. Press again to resume the display measurement. value.
8. The box is placed indoors in a dry and level place without the use of other fixtures.
9. When the temperature rises to the required working temperature (from the red digital display), the indicator light alternately turns off and is the constant temperature point. (It is very likely that the reading will continue to rise at constant time, and this and the residual heat will be stable after about half an hour)
10. If you want to observe the sample of the studio, you can open the box and observe it through a glass door in the box. However, it is better to open the door in order to avoid affecting the constant temperature, and when the temperature rises to 300 °C, open the door. It may cause the glass door to cool and rupture.
11, a copy of the box attachment instructions
12. After the temperature is constant, it can be used according to the test, so that it can be kept at a constant temperature for a certain period of time. In this process, the temperature control device can automatically control the temperature without manual management.
