Constant temperature incubator use and maintenance

The constant temperature incubator uses and maintains a constant temperature incubator, also known as a water-blocking electrothermal cell (mold), which has good temperature performance and temperature uniformity, and is available for scientific research departments such as medical and health, pharmaceutical industry, biochemistry, industrial production and agricultural science. For bacterial culture, breeding, fermentation and other constant temperature tests. Its use is as follows:

1. Turn the power switch to “l”, the power indicator light is on, and there is a digital display on the temperature controller;

2. Temperature setting a. When the required cooking temperature is the same as the set temperature, there is no principle setting, otherwise it needs to be reset. First press the function key “SET” of the temperature controller to enter the temperature setting state, the SV setting display flashes and flashes, then press the shift key “◢” with the plus key “△” or the minus key “” to end the setting. Confirm with the function key "SET".

b. If you do not need to set 37~C, the original setting is 26.5~C, first press the function key “SET”, then press the shift key “◢” to move the cursor to the display ten digits, then press “△” To increase the ten digits from "2" to "3". After setting the ten digits, move the cursor to set the digits and quantile numbers in turn, so that the set temperature is displayed as 37~C, press the function key "SET" "Confirm, the temperature setting is over.

3. Temperature display value correction Since the product has been rigorously tested before leaving the factory, it is generally not necessary to make corrections. If the environment is not good when the product is used, if the outside temperature is too low or too high, it will cause the temperature display value to be in error with the actual temperature inside the box. If it exceeds the technical specifications, it can be corrected. Specific steps: press the function key “SET” for 5 seconds, the instrument enters the parameter setting cycle state “ALl”, continue to press the function key “SET”, make “display” SC” correction, then press the shift key “” to add When the key "△" or the minus key "▽" is operated, the temperature correction can be performed. After pressing the "SET" button, the temperature display value correction is completed.

4. Upper limit tracking alarm setting If the product has been set to 10C high before leaving the factory, do not set it. If you need to reset the function key "SET" for 5 seconds, the meter enters the upper limit tracking alarm setting state "ALl" and then press the shift key "â—¢" with the plus key "â–³" or the minus key "â–½" operation, press after zui Confirm with the function key "SET". The tracking alarm setting ends.

5. After the setting is completed, each data is saved for a long time. At this time, the incubator enters a warming state, and the heating indicator lights up. When the temperature inside the box is close to the set temperature, the heating indicator lights up and down, and the control is entered into a constant temperature state.

6. Open the inner and outer doors, put the items to be cultivated into the incubator, and close the inner and outer doors. If the inner and outer doors open for too long, the temperature inside the box fluctuates somewhat. This is normal.

7. Select the culture time as needed. After the culture is finished, turn the power switch to “0”. If you do not remove the item immediately, please do not open the door.

8. If you have high requirements on temperature control accuracy and fluctuation, you can use PID self-tuning control. When the temperature inside the incubator will reach the set temperature, press the function key “SET” for 5 seconds, the instrument will enter. Set the cycle status “ALl”, continue to press the SET” key to display “ATU”, SV displays “0000”, then press the “△” key to make the SV display “0001”, and press the function key “SET” to confirm. At this time, the auto-tuning indicator lights up, and the temperature controller enters the PID self-tuning control.

Maintenance and maintenance 1. The metal casing of the incubator must be grounded to ensure safe use;

2. The inside and outside of the box should be kept clean and should be cleaned after each use. Long-term use should not cover the plastic dust cover and put it in the drying room;

3. Arrange full-time staff to properly train them according to proper operation and maintenance instructions.

4. Do not over-extrude the contents of the box, and make room for it;

5 Incubators should be placed in a well-ventilated room with no flammable or explosive materials placed around them.
