1. Install one iron-plate knife switch in the power supply line for the purpose of this box, and use the wire which is twice as thick as the power line as the grounding wire and effectively ground. 2. Before powering on, check the electrical performance of the box and pay attention to whether there is an open circuit or leakage. 3. 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 10mm. At this point, you can connect the power supply and start working. 4. 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. 5. After the power is connected, the power heating switch can be turned on, and when the required temperature is higher than 150 °C, it can be turned to the high temperature range. Otherwise, it is not necessary to open the high temperature, just the power supply file, and then turn the temperature controller knob to the desired temperature point in the clockwise direction of the “0†position. At this time, the temperature inside the box starts to rise, and the green light of the instrument lights up as an indication. At the same time, the blower switch can be turned on to start the blower. 6. When the temperature rises to the required working temperature, the green light turns off and the red light is on. At this point, the indicator light alternately turns off and is the constant temperature fixed point. (At the constant temperature point, it is very likely that the temperature will continue to rise. This is the effect of residual heat, which will stabilize after about half an hour.) When the indoor temperature is stable, the red numbers of type 101A and 202A indicate that when the reading exceeds or falls below the required temperature, Adjust the knob slightly to achieve the correct level. The 101 and 202 series can be inserted into a thermometer of 0-300 °C at the top of the box for the temperature in the reference box. The adjustment method is clockwise temperature rise and counterclockwise cooling. 7. 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 can be automatically controlled by the in-tank thermostat without manual management. 8. To observe the sample of the studio, open the door and observe it through a glass door inside the box. However, the door is not normally opened, so as not to affect the constant temperature, and when the temperature rises to 300 ° C, opening the door may cause the glass door to cool and rupture.
