here is a reading „Err4“ on LCD display. It is internal device error during pressure
sensor initialization. Under this condition device does NOT measure atmospheric pressure.
Value read from device is -999.9. Pressure sensor is probably damaged. It is a serious error,
contact distributor of the device.
Readings on LCD display
°C, °F
- reading next to this symbol is measured temperature or error state of value.
%RH
- teading 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.
If specific enthalpy is selected, there is shown only value (number) without corresponding unit!
