2. [Stirring] Button: Press this button to turn on the stirring indicator light and adjust the potentiometer to start the motor, enabling the stir bar to stir. If stirring is not required, press the button again to turn off the stirring indicator light and stop stirring.
3. [Cooling] Button: Press this button to activate the cooling indicator light and start the air pump. If cooling is not required, press the button again to turn off the cooling function and stop the air pump.
4 [+10] Each press of this key increments the tens digit by one. (This key has no effect when the device is in operation.)
5【+1】 Each press of this key increments the units digit by one (this key has no effect when the device is in operation).
6. [Start/Stop] Button: The first press of this button illuminates the start indicator light and simultaneously activates the stirring, heating, and cooling outputs. The [Heating] button controls the heating output, the [Stirring] button controls the stirring output, and the [Cooling] button controls the cooling output. At the same time, the timer begins counting down; when the timer reaches zero, the start indicator light turns off, all outputs are shut down, and the alarm continues to sound. Pressing the button a second time stops the alarm. If the button is pressed a second time while the system is running, all outputs are shut down, the timer stops, and the system ceases operation.
