Note: 1. Add liquid medium into the tank, and the liquid level should not be lower than 20㎜ on the worktable. 2. Selection of liquid medium: A. At room temperature + 8 ℃-80 ℃, the liquid medium generally selects pure water. B. When the working temperature is 80 ℃ ~ 90 ℃, the liquid medium generally uses water-oil mixture. C. When the working temperature is above 95 ° C, the liquid medium generally uses oil, and the open cup flash point of the oil should be higher than the working temperature by more than 15 ° C. (Note: The working temperature here refers to the temperature to be reached by the liquid medium in the tank.) 3. Connection of the circulation pump: A. Connection of the internal circulation pump, connect the outlet pipe to the inlet pipe with a hose (random configuration A hose). B. The external circulation pump is used for external circulation connection. Connect the outlet pipe with a hose to the inlet of the outer tank container, and connect the inlet pipe to the outlet of the outer tank container. 4. If the working temperature is> 100 ℃, it is recommended to use metal pipe or high temperature resistant silicone pipe for the connecting pipe. 5. Plug in the power, turn on the "power" switch, turn on the "cycle" switch. 6. The operation of the instrument is as follows: A. Description of the instrument keys:
Shift key
Plus key minus key SET Setting function key B. Temperature setting: Press the setting function key to enter the temperature setting value setting state. The last digit of the set value flashes. At this time, press the shift key and then the plus key to set the working temperature you need. Then press the set function key and save the set value. At this time, the measurement shows the liquid in the current tank The temperature of the medium, after which the microcomputer enters the automatic control state. The set working temperature should be higher than the indoor temperature + 8 ℃. C. Description of other parameters: a, SC means measurement correction T: means time proportional period P: means time proportional band I: means integral coefficient d: means differential coefficient b, press setting function key to automatically enter other parameter settings after 5 seconds Value status, the measurement window displays "SC" at this time, press Jianjian or Jianjian to set the parameters you need, and then press the function key, the measured value window displays "T", press the plus or minus key to set The parameters you need can be deduced by analogy until all the parameters are completely modified. Then press the setting function key for 5 seconds to restore the normal control state and save each setting value. Note: 1. At the end of setting the working temperature and other parameters you need, and within 15 scales, press the setting function key to save the setting value. If the setting value exceeds 15 seconds, the original setting value will be automatically restored. 2. Under normal circumstances, please do not modify the parameters yourself, except for the measurement value correction can be modified. 7. When the measured value reaches the working temperature, refer to the thermometer required in the experiment inserted in the tank, correct the temperature difference between the measured value and the actual tank (the operation method is the same as (b) in Article 6C), and stabilize for a period of time. Can be experimented or tested.
