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

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.
