Readings will be updated every second. Note: When the meter 
experiences extreme environment changes (ex. from high to low 
temp.), it will take 30 sec for the CO

 sensor to respond and 30 

minutes for the RH sensor. 

2.  Press the “DP/WBT” button to switch the temperature display from 

air temperature, dew point, and wet bulb.
