Co 2 Concentration Calibration - Haier HCP-80 Operating Instructions Manual

CO concentration calibration
2
This series of incubators use a state-of-art infrared (IR) sensor rated at high temperature of 190°C.
You can calibrate the sensor by entering the CO
parameter calibration.
Parameter calibration can be classifi ed as:
1.Air calibration
Ensure good ventilation before calibration - low CO
maximum ventilation volume of the indoor ventilation system or open the windows.Open the
incubator door and wait for ten minutes. Click the air calibration button.
Caution Keep a minimum count of people in the room as each person will increase the CO
concentration. If there are several incubators in the room, it is recommended to use nitrogen for
air calibration. You can purchase a standard nitrogen and calibration kits from Haier or agencies
designated by Haier.
Warning If the display screen shows that the CO
venting or opening the window for ten minutes, turn off all CO
perform air calibration again. If the display screen shows that the CO
than 0.5%, use nitrogen for air calibration. You can purchase standard nitrogen and calibration kits
from Haier or agencies designated by Haier.

Place the third-party detector probe at the center of the incubator;
Close all doors of the incubator and set the CO
entire incubator, including the cord hole on the back.
After achieving stable operation, directly input the value displayed on the third-party detector into
the numerical calibration for saving.
