3、 Structure

  This product is flume type, with a cover for each hole. The inner pot is made of 304 stainless steel. The shell is made of high-quality thin plate and sprayed with plastic. The electric heating tube is installed in the middle of water, which can heat quickly and save power consumption. It is equipped with a digital constant temperature device. The four holes can independently control the temperature and stir independently.                                                                                              

4、 How to use it

  1. When using, water must be added into the pot first, and then the power supply is connected. To set the temperature, press the set key to enter the temperature setting mode to set or view the set value. Press the set key to see the number flashing. In the setting mode, press the up button to increase the setting value and the down button to decrease the setting value. If you keep pressing the button, it will increase or decrease to the value you need. After setting, press the set button again to exit the setting mode and return to the normal working measurement mode.

   2. Adjust parameter SC: press set key for 3 seconds and enter the internal parameter setting and adjustment interface. The interface shows that SC is the error calibration value, which indicates the error between the measured value and the actual value of the temperature controller. The default value is 0.0. You can press the set key again to display the flashing number to enter the adjustment state (the following parameter setting method is the same), and press the up or down button to adjust the value. （-9.9~9.0）

   e: after setting, press the set key to enter the next parameter adjustment. The interface shows that e represents the advance of breakpoint control (only effective when p value is set to 0), and the default value is 0.5. The adjustment method is the same as that of SC.

   P: press set key again to enter the third parameter. The interface shows that P represents the setting of P value, and the meaning of P value is roughly the starting control temperature = set value - (10 / P value). If it is set to 50 degrees, when p is 10, it means that 49 degrees begin to control; when p is 4, it means that adjustment begins at 47.5 degrees. If the temperature overshoot is too large, adjust the p value appropriately. If the temperature rises too slowly or the control temperature is not reached, adjust the p value appropriately.

   note: the breakpoint control mode is entered when p value is 0. That is, the system PID fails. When the temperature is lower than (set value - E value)  , it will start heating, otherwise it will stop heating.

   C: press the set key again to enter the setting of the last parameter C. the last parameter is temporarily reserved in the system. Please do not adjust it. The default value is 20.0. After setting all parameters, press set key to return to normal working state. Do not add too much water in the pot, so as to avoid water overflowing out of the boiler when boiling. Pay attention to that the water in the pot can not make the electric heating pipe out of the water surface, so as to avoid burning the electric heating pipe and causing water leakage.

5、 Precautions

(1) In order to ensure safety, please connect the ground wire when using.

(2) Do not add water and dry burn.

(3) When not working, the power should be cut off to prevent accidents.
