How do you perform temperature calibration?

1. Fill a 250-ml Erlenmeyer flask with approximately 100ml of water and position it at the approximate geometric center of the shaking platform.
2. Install a thermocouple inside the flask with the thermocouple junction in direct contact with the water.
3. Press and hold the “star” (*) key and using the up or down arrow key, adjust the set point to the desired temperature.
4. Allow the shaker to run until chamber temperature has stabilized.
5. The controller display should now be indicating the set point temperature. Make note of the thermometer reading.
6. Press and hold both arrow keys until the controller display indicates “tunE”. Release the arrow keys. Press and release the down arrow key, the display should now alternate between “LEUL” and “1”. Press and hold the “star” () key and using the up arrow key adjust the display to read “3”. Release the “star” () key. The display should now alternate between “LEUL” and “3”. Press and release the up arrow key until the display indicates “Zero”. The display should now alternate between “Zero” and a numerical value.
7. Using the examples shown in the table and the thermometer value obtained in Step 5 above, enter the correct “Zero” value into the controller by pressing the “star” (*) key and using the up or down arrow key. If there is already a “Zero” value present, then add the new value to the one already present.
8. When the correct “Zero” value has been entered, press and hold the two arrow keys together until the display again indicates the chamber temperature. If the procedure was done correctly, the controller display should now agree with the thermometer reading to within ±0.5°C.
9. Allow the unit to run for at least an additional 30 minutes.
