2.2 Overview of structure and function
BIGP 200 series series electric thermostatic incubator consists of:
Box - The outer shell is made of steel plate, and the surface is sprayed with plastic; The inner liner is made of mirror surface rusty steel, and the four corners of the semicircular arc are easy to clean. The shelf spacing inside the box is adjustable.
Heating - Electric heating.
Circulation - The box is equipped with a motor, which operates through a fan to force the smooth circulation of gas in the working chamber to improve temperature uniformity. At the same time, it has the function of fast and slow speed change.
Control - Microcomputer type electronic controller, sensor using Pt100 platinum resistance temperature control accurate, stable and reliable.
Protection - With multi-level independent overtemperature protection and alarm system:
【One level overtemperature protection 】: The controller is equipped with an upper deviation alarm function, which allows users to adjust the deviation AL1 parameter as needed and set it by themselves.
【Second level overtemperature protection】: When the actual temperature of the equipment exceeds the set protection value for the high temperature limit, the power supply to the heating section is automatically cut off, and an audible and visual alarm is issued.". Due to the fact that the circulating fan still
operates normally during an alarm, the alarm will automatically be cleared when the temperature is lower than the set value. (User option)
Convenience - (BIGP-201-BIGP-202) Direct observation through the inspection window of the box door, convenient and clear. While (BIGP-203~BIGP-206) have dual interior and exterior box doors, which can be opened for observation through a glass interior door. When the doors of the desktop (BIGP-201-BIGP-202 )box and the glass doors of the (BIGP-203~BIGP-206) box are opened, the breeze circulation automatically stops, reducing the temperature "overshoot" caused by opening/closing the box door. The vertical BIGP-501~BIGP-503 doorless switch does not have this function.
(BIGP-201-BIGP-206) models can be optionally equipped with a liquid crystal display controller or a multi stage programmable liquid crystal temperature controller. (BIGP-201-BIGP-206) Type B is a liquid crystal display controller (see VI, Instructions for the Use of Liquid Crystal Display Controllers), optionally equipped with a multi stage programmable liquid crystal temperature controller.

*"↑"Used to adjust parameter values or observe timing remaining time/timing recovery.
*"↓"Used to adjust parameter values or enable/disable self setting status/current real-time power, i.e. SV displays "o 100".
3.2.1 Turn on the power switch. At this time, the power indicator light is on, the controller PV screen displays the measured temperature, and the SV screen displays the set temperature.
3.2.2 Close the glass door and the box door, and the motor runs. At this time, the incubator enters the working state.
3.3 Temperature setting
3.1 (See Figure 6)Click"SET"key, The PV screen displays " 
", SV screen displays the set temperature value.
3.2 Use "←" to cycle through the flashing bits displayed on the SV screen.
3.3 Use "↓" or "↑" to change the value of the flashing bit on the SV screen until the desired temperature value is reached.
3.4 Click again "SET" key, Return to operating mode (PV screen display measure the temperature, SV displays the set temperature, and enter the working state.
Figure 6
3.4 Timing setting
1. See figure 7, After pressing the SET key for 4 seconds, the PV
screen displays" 
", if SV screen display "0", it indicates that timing function not set (factory status).
2. Press the SET key several times, until PV screen display"LK ", trough 
key make the SV screen display 3 (timed unlock), press again SET key, PV screen return" "trough key, set the required value for timing (timing range: 1 to 9999 minutes), press the SET key again for 4 seconds, and the controller returns to the working mode. The timing starts to run. At this time, the AT light flashes, entering the calculation time. When the timing ends, PV and SV windows are displayed "End", the AT light goes out and the buzzer beeps 4 times to indicate a reminder.
3. Timing recovery: Press and hold the key until the instrument enters the working mode, and still operate at the original set timing time.
4. Self setting is not allowed after a timed start. To observe the running time, press the key once, and the SV screen displays the remaining time value. (Note: The determination of the total timing time should consider the combined calculation of temperature rise and constant temperature in two stages).
5. During timed operation of the product, it is allowed to modify the timing time "ST". The previous accumulated running time is "memorized" and runs to the new timing time. The product stops heating, and the buzzer beeps. (When the new timing time is less than the previous cumulative operating time, the heating output is immediately turned off and the buzzer sounds.)
6. When the power is cut off during operation or the power is turned off and then restarted, the timing needs to be reset.
3.5 Check temperature control accuracy
1. Select a digital thermometer with a resolution of 0.1°C that has passed the verification and is within the verification period as a standard and put it into the product work room, and ensure that the sensor temperature sensor is in the geometric center of the work room.
2. Choose a point within the temperature control range of the product and set the SV temperature control value. When the PV measurement value is equal to the set value, keep it at a constant temperature (1~2) hours or so (depending on the product specifications, the constant temperature time may vary) , Observe that the difference between the actual measured temperature value of the standard thermometer and the measured value displayed by the controller PV should be ≤±0.5°C.
3.6 High/low speed settings
1. Yellow lamp(COLD/AL2)light, high speed operation of fan.
2.(See figure 8)When the temperature reaches: PV = SV +Fn, That is, from high speed to low speed operation, and the yellow light goes out at this time.
Figure 8
3.7 Methods for improving the accuracy of temperature control.
1. Error correction between measured temperature and actual temperature in the working room.
1.1 Press "SET" key more than 4 seconds (enter menu B), when PV screen display " " just release, press SET key Several times, find the "LCK" prompt.
1.2 Press " "key, make the SV screen display 18 (unlock).
1.3 Press again "SET" key Several times, find the "Pb" prompt for the control parameter that needs to be adjusted, and press the function key to display the control parameter as the desired value. Pb = Original Pb value +(Actual temperature - PV display value)
1.4 Calculate the "Pb" value according to the above formula, and input it. (If the adjustment is not correct at one time, it can be repeated multiple times until it meets the standard.).
1.5 If Pb has been adjusted to the maximum (out of range) and cannot be adjusted again, set "Pb" to 0 and return to the working state.
1.6 Press the "SET" key, and "PK" will appear on the PV screen. Modify the "PK" to 1.000, and then return to the working state.
1.7 Select 1 test point within the temperature range, such as:
PK=4000*(Standard values of the recorder - displayed temperature measurements)/Displayed temperature measurement (be sure to retain three decimal places)
1.8 Set a new "PK" parameter value, and if it is no longer accurate, adjust the "Pb" according to the steps in 1.3 of this chapter (repeatedly until it meets the standard).
2. Suppression of temperature instability (causing up and down fluctuations or excessive overshoot).
2.1 Refer to 1.1 of this chapter to enter the B menu.
2.2 Increase the parameter "P" (proportional band) by about 0.5 each time.
2.3 Simultaneously change the parameter "I" for about 100 seconds each time, and simultaneously change the parameter "D", D=I/4, and observe the temperature again until the temperature overshoot meets the requirements.
2.4 If it still cannot be eliminated, refer to Section 7.1.6 of this chapter to enter the B menu.
2.5 Find "HP" (output power) and reduce it by about 10% each time.
2.6 Self setting startup/shutdown: Hold the key for a long time, the AT light will be on for a long time during self setting, and the SV window will alternately display the SV value and the words "- AT -"; At the end of self setting, the AT light goes out.
2.7 When the required temperature is low, a secondary setting method can be used to reduce temperature overshoot.
(For example, when the required temperature is 40 °C, set 38 °C first, and then set 40 °C after the temperature is basically stable, which can reduce or even eliminate temperature overshoot.)
3.8 Our suggestion
1 When the set temperature "SV" is close to RT (ambient temperature)+5 °C, use the secondary setting method (see Chapter 3, Article 7.2.7)
2 If the humidity in the box is found to be too low during work, a water pan can be placed inside the box. Through natural evaporation, the relative humidity can generally reach about 90% (the water pan only provides a humidity environment and cannot control humidity).
3.9 Call out sequence of each function
3.10 Use of optional accessories "independent temperature limit controller"
The over-temperature protector is an independent protection system. When the temperature controller fails and the temperature is out of control, when the temperature in the working room reaches the temperature limit setting value of the over-temperature dial, the over-temperature protector will automatically cut off the heating and sound an alarm.
(As shown in the right picture) When the temperature
in the working room is lower than the temperature limit. After the set value, the protection system is eliminated and the instrument resumes work.
Repeat this way until the fault is eliminated.
Figure 9
The specific operations are as follows:
1. The temperature limit setting value should be greater than or equal to • (SV+AL) + (10~15)°C
2. See Figure 2, use the + and-buttons on the over-temperature setting dial on the panel to set the required temperature limit.
Example: SV=130°C, AL=10 Then 150°C should be set up.
