•    When the reading is stable and close to the selected calibration point, the

CFM 

functional key is displayed.

• Press 

CFM

 to confirm.

• The second expected calibrated point is displayed.

• Immerse the probe into the second vessel as close as possible to the reference

thermometer. Allow a few seconds for the probe to stabilize.

• Use the 

ARROW

 keys to set the calibration point value to that measured

by the reference thermometer.

• When the reading is stable and close to the selected calibration point,

CFM 

functional key is displayed.

• Press 

CFM

 to confirm. The instrument returns to measurement mode.
