Liquid crystal biochemical incubator debugging method
1. A method of correcting the difference between the temperature inside the box and the display temperature.
Prerequisites: The device has the function of correcting temperature. Because the equipment varies with the area, climate and usage environment, when you perform temperature detection, you may find that the temperature measurement equipment (such as thermometer) is used in the box. The temperature (called the actual temperature) does not match or differ greatly from the temperature displayed by the temperature controller (called the display temperature), and temperature correction can be performed at this time.
1. In the display state, press the “SET†button, the current value: display SEL status, when the setting value is 0000, press the move button to move the flashing digit, press the plus or minus button to enter the value “0111â€.
2. Press the “SET†button again to enter the temperature parameter correction mode. The current value is displayed as: 1SC.
The value of the set value is adjusted. If the actual temperature (the temperature measured by the thermometer) is different from the displayed temperature, the measured value of the studio thermometer is subtracted from the displayed temperature value of the meter, and the result is the actual correction value of "1SC". . If the measured value of the working temperature of the working chamber is smaller than the temperature value displayed by the meter, the corrected value obtained is a negative value, and vice versa. Use the move button to move the flashing number and press the plus or minus button to set the desired temperature.
3. After setting, press and hold the “SET†button, the current value will display “1HLâ€, set the slope correction, do not change the default value (100), and then press the SET button continuously to return to the display state. It has been corrected to work.
