End of procedure 

 

Calibration Continued 

 

Once the chamber has stabilized, compare the reference 

temperature device and oven temperature display readings. 
 

a.

 

If the readings are the same or the difference between the 

two falls within the acceptable range of your protocol, the 

display is accurately showing the chamber temperature. 

The temperature calibration procedure is now complete

 

b.

 

See Step 9 if a difference falls outside the acceptable 

range of your protocol again. 

Reference Device 

 

 

 

Repeat steps 2 – 8 up to two more times. 

 

 

Three calibration attempts may be required to 

successfully calibrate ovens that are more than ± 2°C out 

of calibration. 

Reference Device 

 

 

 

 

If the temperature reading difference still falls outside your protocol after three (3) calibration 

attempts, contact your distributor or

 Technical Support

 for assistance.
