V. Detail and Instructions

 

1, The operator need to read carefully the instructions, understand familiar with incubator, to operate.

 

2, Processing power, the power switch to "1", the power indicator lights, instrument by about 4 seconds after self-checking, in normal state of measurement and control, PV on the window display measurements, discharge SP window shows the set value.

 

3, Temperature setting:

When the heating temperature and set temperature at the same time, do not need to set, need to set conversely.If you want to modify the setting, please in standard display mode, press the function key, PV window shows "SP", SP window display has set of values, press up key to up at this time adjustment Settings or press down downward adjustment Settings (long hold key or button can realize continuous quick rise or drop), then  confirm modify button to finish.

For example: the need to set temperature 37.0 , the original set temperature 25.5 , first press the  button, PV window shows "SP", then press , make the SP window display, "37.0" button to  confirm again, end temperature setting.

 

4, In addition to the temperature set value other than "SP" parameters, after the products pass strict inspection before they go out, have given set.If users want to modify the parameters, Settings, click on the steps: press the up key about 4 seconds:

 

A) PV prompt window display control cycle "T", the value of the discharge SP window display has been set at this time press button "" rising or falling is "" operation, press function key to  confirm again (control cycle should not be commonly modified).

B) PV window shows proportion with prompt "P", SP window display has been set of values, at this point, key operation key or press  confirm again.

C) PV window display integral time prompt "I", SP window display has been set of values, at this point, key operation key or press  confirm again.

D) PV window display differential time prompt "d", SP window display has been set of values, at this point, key operation key or press  confirm again.

E) PV window display timing time prompt "ST", SP window shows "OFF" (factory setting), closed this time of the timing function.If open timing function, intelligence, key or button set timing time  bring again to confirm.In standard display mode, press the  function key is PV window shows "ST", discharge SP window shows the values for the remaining time regularly.If the SP window shows "OFF", the timing function has been closed.

F) PV insensitive area prompt window form "dF", SP window display has been set value, the press or button operation, according to the  determined again.

G) PV window display limit alarm prompt "leisure", SP window display has been set of values, at this point, key operation  key or press  confirm again.
H) PV deviation revised prompt window shows "rE", SP window display has been set value, bring about key or button at this time Operation, according to  confirm again.


5, After the setting, the long-term preservation of data.When heating drying box into the state, output work OUT (green) light shine.When the temperature in the cabinet near the set temperature, burn OUT on and off lights and repeatedly, entered into a state of constant temperature control.

 

6, Open inside and outside the door, put the items needed to develop into the incubator, close both inside and outside the door.If open inside and outside the door for a long time, the temperature in the cabinet some fluctuations, this is normal phenomenon.

 

7, According to need to select training time (open timing function, according to the 4 e) operation).

 

8, after the training, with the power switch to "0".If you don't take out the goods immediately, please don't open the door.

 

9, At the same time also can by opening the self-tuning function to realize the automatic setting of PID parameters.Specific steps: just press down four seconds, self-tuning flashing AT (yellow) lights, temperature control into PID self-tuning control.After a period of time since the end of setting, the board AT the lights, the setting of the proceeds of the new PID parameter value has automatically deposited, and according to the new PID parameter control.

 

10.When you start the self-tuning function should pay attention to the following:

 

 

 

A) please make sure before you open the self-tuning function value, the setting of parameters for only the relative parameters should be set points in the system.

 

B) since the end of setting, set the PID parameters automatically, even to cut off the power supply, the setting of PID parameters will be saved, so keep running, don't need to be self-tuning, unless you want to change the set point, will be reopened self-tuning function.

 

C) during the self-tuning is according to the common two type adjustment instrument to control system, according to different process, PV value may be very big change, so even with overshoot phenomenon also is normal.

 

D) in the condition of self-tuning, to immediately end self-tuning function, as long as according to the function keys, self-tuning was suspended, instrument control according to the original PID parameters.

 

 

 

VII. Attention

 

1. The casing must be reliable grounding, in order to ensure safety.Electricity don't open the box, electrical lines on the left side of the door, prevent to get an electric shock, do not in wet cloth touch, more can't wash with water.

2. Try opening the door to observe things, not to point water splashing on the glass, in case of glass by cold and violent.

3. The mobile housing must cut off power supply first, remove the items in the cabinet, prevent to get an electric shock and clash.

4. This model is non explosion-proof products.

5. Flammable items should not be in for baking in the oven test, if you need for baking test, should be measured combustion temperature of each items in advance in case of combustion.

6. Always keep clean body and electrical circuitry, if a failure occurs should stop using the relevant units to repair.
