Error 1
Measured (calculated) value is over upper limit of allowed full scale range. There is a reading
„Err1“ on LCD display. Value read from the device is +999,9.
This state appears in case of:
• Measured temperature is higher than approximately 600°C (i.e. high non-measurable
resistance of temperature sensor, probably opened circuit).
• Relative humidity is higher than 100%, i.e. damaged humidity sensor, or humidity
calculation of humidity is not possible (due to error during temperature measurement)
• Computed value – calculation of the value is not possible (error during measurement of
temperature or relative humidity or value is over range)
Error 2
There is a reading „Err2“ on LCD display. Measured (calculated) value is below lower limit of
allowed full scale range. Value read from the transmitter is -999,9.
This state appears in case of:
• Measured temperature is lower than approximately -210°C (i.e. low resistance of
temperature sensor, probably short circuit).
• Relative humidity is lower than 0%, i.e. damaged sensor for measurement of relative
humidity, or calculation of humidity is not possible (due to error during temperature
measurement)
• Computed value – calculation of computed value is not possible (error during measurement
of temperature or relative humidity)
Error 3
There is a reading „Err3“ on LCD display upper line.
Error of internal A/D converter appeared (converter does not respond, probably damage of A/D
converter). No measurements proceed. It is a serious error, contact distributor of the instrument.
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.
°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!
symbol 3 near by left display margin
Is on if jumper is closed.
