Dnp-9052-1a intelligent temperature control and high precision

1、 Scope of application

  It is the necessary equipment for storage of bacteria and biological cultivation in medical and health, medicine, biology, agriculture, scientific research and other departments.

2、 Technical index

3、 Structure overview

  The external shape of the electric constant temperature incubator is vertical, the box body and the outer box door are made of high-quality steel plate, the surface is electrostatic spraying, and the inner door is made of toughened glass. The cultivation articles in the box can be clearly observed without opening the inner door. The workroom adopts steel plate or stainless steel plate, and the shelf can be easily moved and the height of the shelf can be changed arbitrarily. A silicone rubber sealing ring is installed between the working room and the inner door of the toughened glass, and a small low-noise fan is installed on the top of the working room, which is blown by the breeze to ensure the temperature uniformity in the box. The box shell and the working room are filled with ultra-fine glass wool for heat insulation.

  The power switch, power indicator and temperature control instrument are all set on the upper part of the incubator. The temperature control instrument has high temperature control precision. The set temperature and the temperature in the box are both digital display. The set temperature has protection device and tracking alarm function.

4、 How to use it

1. 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 on the upper row of the digital display meter 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 it, it will increase or decrease to the value you need. After setting, press set button again to exit the setting mode. Time setting: press set key to press to Set the time in the lower row of the digital display meter. Set it randomly according to your own needs of 0-999 minutes. Then press the set key to enter the confirmation mode and return to the normal working measurement mode.

2. Adjusting parameters

   SC: press the 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. （-9.9~9.9）

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). The default value is 0.5, and the adjustment method is the same as that of SC.

P: Then press the set key to enter the third parameter. The interface shows that P indicates 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: 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.

c: Press set key to enter parameter C. the last parameter is reserved in the system temporarily. Please do not adjust it. The default value is 10.0.

Al: press the set key to enter the setting of parameter Al, which indicates the high temperature alarm value. That is, when the temperature > set temperature + Al, the instrument will alarm at high temperature.

Ti: press the set key to enter the setting of parameter ti. Ti is the timer and the unit is minutes. 0 means that the timing mode is off; otherwise, when the Ti value of the instrument works for minutes, it will enter the stop state and stop the output of the load end.
After setting all parameters, press set key to save parameters and return to normal working state.

3. During the cultivation of articles, it is better not to open the inner door of the glass, especially for a long time, so as to avoid affecting the temperature.

4. Select the cultivation time according to the needs. After the cultivation, turn the power switch to "O". If you don't take out the articles immediately, please don't open the box door.

5、 Precautions

1. The outer shell of the incubator must be effectively grounded to ensure safe use.

2. The incubator should not be placed in the room with good ventilation conditions, and inflammable and explosive materials should not be placed around the incubator.

3. The articles in the box should not be too crowded, and space must be reserved.

4. The inside and outside of the box should be kept clean. If it is not used for a long time, it should be covered with plastic dust cover and placed in the drying room.

5. It is normal to have overshoot at the beginning of each use. The culture should be placed after the temperature is stable.
