2、 Structural features:
3、 Technical parameters:
| Instrument model | Heating power (W) | Working volume (mm) | Working power supply (V) | Constant temperature range (℃) |
| HH-W420 | 1600 | 420*180*200 | 220(alternating current) | Normal temperature + 5-99.9 |
4、 Usage:
2. Adjust parameter SC: press the set key for 3 seconds and enter the internal parameter setting adjustment interface. The interface shows that SC is the error calibration value, indicating 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）
3. E: after setting, press set 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 SC.
4. P: press the 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.
5. Note: when p value is 0, the breakpoint control mode is entered. 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.
6. C: press the set key again to enter the setting of parameter C. the parameter is reserved in the system temporarily. 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.
