Selecting the Operating Mode
Long press the M (Mode) button to scroll through the list of functions. When the desired mode
is displayed, release the button. See display icons with brief descriptions below:
• An Anemometer (Air Velocity plus Air temperature)
• AirFL Air flow (Volume) in CFM and CMM units
• CHiLL Wind chill temperature
• rH Relative Humidity in % and Air temperature
• dP Dew point temperature
• _Et Wet bulb temperature
• HEAt Heat index temperature
• LigHt Light intensity measurements
• tYPE Type K thermocouple temperature (must attach thermocouple to meter)
Changing the Units of Measure
