Troubleshooting
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 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.
It is a serious error, contact distributor of the device to fix.
Error 1
- t
here is a reading „Err1“ on LCD display. Measured temperature
is over upper limit of allowed full scale range. 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).
Error 2
- t
here is a reading „Err2“ on LCD display. Measured temperature
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).
Error 3
- t
here 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. 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 -999. It is a serious error, contact distributor
of the device
