Temperature Calibration 

   

 

 

 

 

 

 

     

     

 

To  calibrate  the  temperature,  take  a  certified  calibrated  thermometer  in  a  small  bottle  with 
glycerin and place that in the geometrical center of the incubator. 

 

11.1 Low Temperature Point Calibration (0.0) 

a)  Change the set point to lower temperature value, 37°C for HEATING ONLY UNITS (or 8°C for 

REFRIGERATED UNITS,) and let the incubator run for at least 1 hour

– until the temperature is 

constant, and let the temperature inside of the chamber uniform. 

b)  Read the temperature on the thermometer through the glass lid; calculate the difference with 

actual displayed temperature. for example, if reading is 35°C, difference would be 35-37= -2°C, 
while if reading is 38°C, the difference would be 38-37=1°C 

c)  Press  the  "Set/Confirm"  button  and  go  with  the  up  arrow 

to code “7”. Press  the  Set/Confirm 

again,  to  enter  the  Step  1.  "Low  Temperature  Point  Correction  (0.0)",  the  display  shows  the 
"Temperature  Calibration"  with  "0.0"  and  the  "Current  Calibration  Value".  Use  the  up  and/or 
down  key  to  make  a  further  adjustment  on  the  current  correction  value  by  the  temperature 
difference calculated above, for "-2°C ", decrease by 2, for "1°C ", increase by 1. 

d)  Keep  pressing  "Set/Confirm"  button,  skip  the  "  High  Temperature  Point  Correction  (100.0)" 

setting, save and exit. 

e)  The  displayed  temperature  should  have  changed  due  to  the  calibration.  Waiting  for  another 

one hour to let the temperature stabilize again at 37°C, and check the thermometer value again, 
and calculate the new difference.   

f)  if necessary, perform the calibration again until the actual display value equals to the calibrated 

thermometer value. Thus the Step 1. "Low Temperature Point Correction (0.0)" is completed. 
 

11.2 High Temperature Point Calibration (100.0) 

a)  If the incubator is to be used for more than one temperature setting, and "High  Temperature 

Point Calibration (100.0)" needs to be performed as well.   

b)  Change the set point to a higher temperature point as required, for example 60.0°C and let the 

incubator  run  for  at  least  1  hour

–  until  the  temperature  is  constant,  and  let  the  temperature 

inside of the chamber is uniformed 

c)  Change  the  enter  the  code  "7"  again  and  press  "SET"  skip  the  "0.0",  and  enter  the  "100.0" 

page. 

d)  Repeat the same procedure, like the "Low Temperature Point Calibration", to correct the high 

temperature  point,  until  the  display  value  equals  to  the  actual  thermometer  value.  Then  the 
"Step 2 High Temperature Point Calibration (100.0)" is completed. 
 

 
 
 
 
 
 
 
 
 
 
 

          

   

Special Attention! 
 

Temperature  of  each  unit  has  been  carefully  calibrated  in  factory 
before dispatch. 
 
No  further  calibration  is  needed.  But  if  it  does,  do  follow  the 
calibration  process  strictly  or  consult  your  supplier,  as  wrong 
operation can interfere the temperature accuracy significantly.
