Place the display in temperature calibration mode. 

 

a.

 

Press and hold both the 

Up

 and 

Down

 temperature 

arrow buttons simultaneously for approximately 5 

seconds. 

 

b.

 

Release the buttons when the temperature display 

shows the letters “C O”. The display will begin 

flashing the 

current temperature display value

. 

 

Note:

 The display will automatically exit calibration mode after 

5 seconds of inactivity, with the last shown temperature 

display value saved. 

 

 

 

 

 

 

4 

 

 

Use the 

Up

 or 

Down

 arrows to adjust the current 

display temperature value until it matches the 

reference device temperature reading. 

 

Reference Device 

 

 

 

5

 

 

 

After matching the display to the reference device, 

wait 5 seconds. 

 

•

 

The temperature display will cease flashing 

and store the corrected chamber display value. 

 

•

 

The incubator will now begin heating or 

passively cooling in order to reach the setpoint 

with the corrected display value. 

 

  

 

 

 

 

 

Cooling to Setpoint 

6 

 

 

Allow the incubator to operate for at least 1 hour 

undisturbed to stabilize 

after the incubator has 

achieved the corrected temperature setpoint. 

 

•

 

Failure to wait until the incubator is fully 

stabilized will result in an inaccurate reading.
