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
hPa, PSI, inHg
reading next to this symbol is measured pressure or error state of value. If selected
pressure unit is
mBar
or
oz/in
2
or
mmHg
or
inH
2
O
or
kPa
, there is shown only value
(number) without corresponding pressure unit!
°C / °F DP
reading next to this symbol is calculated dew point temperature or error state of value
g/m
3
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
3
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.
