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

point, “

READY

” tag will appear and “

CFM

” tag will blink.

• Press 

CFM

 to confirm. The instrument returns to measurement mode.

Note:  If the reading is not close to the selected calibration point, 

“WRONG” tag will blink. Change the temperature probe and restart 

calibration.
