First, the high and low temperature when the temperature in the experiment, such as the transition temperature is not the temperature of the experiment, when checking for home appliance system software, the fault detection one by one. As the temperature is going up more slowly, but also wind Huxijitong query, regulator diaphragm facie wind Xunhuanjitong is not open as usual, on the contrary, to check the motor running wind Xunhuanxitong is not normal. Such as temperature overshoot interest then we must de-excitation PID setting the main parameters. If the temperature rises immediately, overtemperature protection, then the control board common fault shall be removable actuating dashboard.
Second, when suddenly appear abnormal high and low temperature experiments in the operation of the whole process, common faults appear to match the information displayed on the dashboard to remind manipulation and have voice alarm reminder. Actual operating staff to compare the actual operation of the application of common faults of machinery and equipment in clearing check out the section which belongs to a common fault, fault detection can please professional and technical personnel, everything is normal to carry out experiments. Other environmental testing equipment in the application there will be other conditions, but also that the actual situation, in-depth analysis and clear. Environmental testing equipment also carry out maintenance on time, remove refrigeration unit cooler on time for thematic activities shall be members of the Instructions to oily, household appliances Zidongkongzhi system maintenance check these, this work is indispensable
Third, the high and low temperature ultra-low temperature is not reached on the index value of the experiment, then you have to check the view transition temperature, the temperature drop is slower, the temperature or temperature values have to be after warming trends, in front of that is even check before making ultra-low temperature experiments is not a personal studio air-dry, dry impatient to maintain the personal studio and then put into the test sample in the work room to do experiments in the test work are not placed in the room too much work in the air in the room may not be sufficient Xunhuanxitong, after clearing the reason, but also taking into account the common fault is not in the refrigeration unit, that must be invited Wang Chin equipment manufacturer expertise personnel to carry out maintenance. One condition is a later application equipment Ziranhuanjing initiator is not very good, the working temperature of equipment is placed, the placement portion (rear housing wall spacing) to meet the requirements (the actual device operating instructions in a machine often request).
