Please follow up the procedure for calibration below in case of discrepancy between actual value
(measured by reliable thermometer or device) in chamber and displayed value.
Conduct the analysis of CO

density and Temperature when incubator has been stabilized for more
than 2 hours. Leave the incubator at least 2 hours (preferably overnight) to allow conditions to
stabilize if incubator is just turned ON.
Consider that low deviation range (like ±0.1 ~ 0.3%) may not be corrected precisely by this calibration.
a.
Press and hold “CAL/SET” for 10 seconds. Then, LED will be flickering with signal below.
Chamber’s Main Temp calibration
1 Channel Sensor detects the temperature in chamber. The
sensor is above of circulation fan.
Press “CAL/SET” key to enter Ch1 calibration which is purposed to adjust the value LED display to be
shown in accordance with the actual value of Temperature in chamber. Available range of Calibration
is ±5
℃
.
Press UP (
▲
) the temperature value on LED as much as display difference between actual
temperature and temperature on LED when actual temperature in chamber is higher than value of
temperature display. On the other way, press DOWN (
▼
) the temperature on LED when the
actual temperature is lower than display.
Press “CAL/SET” key again after input. “SAVE” is shown up on LED screen like below.
Shift channel to channel, press “CAL/SET” button. After calibration at 4Channel, the
LED is back to Temperature Display. Press “CAL/SET”
b.
Press UP (

)and DOWN (
▼
)to switch to Ch2 calibration which is Outer door’s Temp
calibration
