Damage to the infrared detector by measuring high scene 
temperatures. 
>  Without high-temperature filter: Do not perform any 

measurements at scene temperatures > 500 °C/932 °F. 

>  With high-temperature filter: Do not perform any 

measurements at scene temperatures > 800 °F/1472 °F.  
With measurements of high scene temperatures (>350 °C or 
>662 °F), always install the high-temperature filter, see 
Mounting/removing high-temperature filter page 18, and set the 
measuring range, see Measuring range page 25 . 

 

 

 

 

With the high-temperature measuring range (

 °C or 

 °F) activated, the stated accuracy 

specifications are not valid for readings below 350 °C or 
662 °F as this range is not calibrated.  

 

Important framework conditions 
Please observe the following framework conditions in order to 
obtain significant measurement results. 
Humidity measurement:  
•  Gently wave the separate air humidity measuring instrument to 

shorten the equalization period. Avoid sources of interference 
(e.g. breathed air). 

Building thermography, investigating the building shell:  
•  Considerable temperature difference between inside and 

outside required (ideal: > 15 °C/> 27 °F).  

•  Consistent weather conditions, no intensive sunlight, no 

precipitation, no strong wind.  

To ensure the highest level of accuracy, the imager requires an 
equalization period of 5 minutes after being switched on. 

Important settings 
Before recording an image, check whether the protection glass 
option is set correctly to prevent corruption of the measurement 
results, Optics... page 32. 
Before saving an image, ensure that it is focused correctly (in 
focus), see Focus image using motor focus page 20 or Manually
