8. Readings on LCD display

°C, °F

reading next to this symbol is measured temperature or error state of value

%RH

reading next to this symbol is measured relative humidity or error state of value

CO2 ppm

reading next to this symbol is measured concentration of CO

or error state of value.

°C / °F DP

reading next to this symbol is calculated dew point temperature or error state of value

g/m

reading next to this symbol is calculated absolute humidity or error state of value

g/kg

reading next to this symbol is calculated specific humidity or mixing ratio (depends on device
setting) or error state of value

this symbol is on if jumper is closed

If specific enthalpy is selected, there is shown only value (number) without corresponding unit.

9. Preventive maintenance and calibration

Pay heed to recommended calibration interval. Do not subject the device to mechanical stress.
