7. Error States of the device
Device continuously checks its state during operation. In case error is found LCD displays
corresponding error code:
Error 0 - first line of LCD displays „Err0“. Check sum error of stored setting inside device’s
memory. This error appears if incorrect writing procedure to device’s memory occurred or if
damage of calibration data appeared. At this state device does not measure and calculate values. It
is a serious error, contact distributor of the device to fix.
Error 1 - measured or calculated value (except concentration of CO
2
) 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).
The value of CO
2
concentration 9999 ppm is correct value!
Error 2 - there is a reading „Err2“ on LCD display. Measured or calculated value is below lower
limit of allowed full scale range or CO
2
concentration measurement error occurred. Value read
from the device 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). 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.
