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). At this state device
does not measure temperature and relative humidity. This error does not affect CO
2
concentration
measurement. It is a serious error, contact distributor of the device.
Error 4 -
there is a reading „Err4“ on LCD display. It is internal device error during CO
2
concentration sensor initialization. Under this condition device does not measure concentration
of CO
2
. Value read from device is -9999 (concentration of CO
2
). CO
2
sensor is probably
damaged. It is a serious error, contact distributor of the device.
Error 5,6 -
there is problem with assigned value to output relay, there is some wrong setting
(mismatch). This error appears if incorrect writing procedure to device’s memory occurred.
Error 9 -
inserted password is not valid, there is shown for short time message “Err9” on LCD
display.
7. 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
2
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
3
- this symbol is on if jumper is closed
If specific enthalpy is selected, there is shown only value (number) without corresponding unit
8. Preventive maintenance and calibration
Pay heed to recommended calibration interval. Do not subject the device to mechanical stress.
