DISPLAY MODES 
The meter may be set to the following display modes: 
Humidity and Temperature (Rh/Tmp)
(Humidity reading shown in the upper display, Temperature reading shown in the lower display)
 
Barometer and Anemometer (Bar/An) 
(Barometric pressure reading shown in the upper display, Anemometer reading shown in the lower 
display) 
Barometer and Humidity (Bar/Rh)
(Barometric pressure reading shown in the upper display, Humidity reading shown in the lower 
display) 
 
Barometer and Temperature (Bar/Tmp) 
(Barometric pressure reading shown in the upper display, Temperature reading shown in the lower 
display) 
 
Anemometer and Temperature (An/Tmp) 
(Anemometer reading shown in the upper display, Temperature reading shown in the lower 
display) 
Humidity and Dew Point (Rh/Dp)
(Humidity reading shown in the upper display, Dew Point temperature shown in the lower display)
To change the display mode, press and hold the REC button until the 
reading on the display begins to flash, then release the REC button. With the 
readings flashing, each press of the REC button will change the display mode 
in sequence 
(Rh/Tmp→Bar/An→Bar/Rh→Bar/Tmp→An/Tmp→Rh/DP→Rh/Tmp...). 
Once the desired display mode appears, release the HOLD button to select 
the display mode (the display will no longer flash). 
 
OPERATION 
1. Press the POWER button to turn the meter on. 
 
2. Select the desired display mode (see the 
 “Display Modes” section). 
 
3. Take the desired measurements. 
 
4. Press the POWER button to turn the meter off. 
 To preserve battery life, always turn the meter 
 off when not in use. 
 
If no button is pressed for ten (10) minutes, the meter will turn off 
automatically to preserve battery life (see the “Automatic Shutoff” section). 
 
SELECTING °F OR °C 
(Temperature/Dew Point)
1. Place the meter into one of the following display
 modes that displays a temperature reading: 
 Rh/Tmp, Bar/Tmp, An/Tmp or Rh/Dp (see the 
 “Display Modes” section). 
 
2. Press and hold the HOLD button for 
 approximately five (5) seconds, the unit of 
 measure will flash on the display. 
 
3. Release the HOLD button and press the REC 
 button, the temperature reading will switch to the 
 opposite unit of measure. If the meter had been 
 displaying °F, it will now display °C, and vice- 
 versa. Each press of the REC button will switch 
 the display to the opposite unit of measure. 
 
4. With the desired unit of measure appearing, 
 press the HOLD button. 
 
The unit of measure selected will be the default unit of measure for both 
temperature and dew point until changed. 
 
SELECTING ANEMOMETER UNIT OF MEASURE 
1. Place the meter into the Anemometer and 
 Temperature (An/Tmp) display mode (see the 
 “Display Modes” section).
