7.2 

Thermal alignment  

When measuring a hot object in font of a colder background, it is usually sufficient to align the optical head 
“thermally” to achieve the highest temperature (output) signal. For this kind of alignment the pyrometer must 
be switched into 1-color mode, because in ratio mode the maximum signal can already be achieved even if 
the object fills the spot only partially.  
 
 
7.3 

Avoiding measuring errors caused by incorrect installation 

To avoid measuring errors, please note the following points when mounting the pyrometer: 

 

Infrared radiation of hot machine parts can be reflected from the measuring object and will be detected 
additionally by the pyrometer. For example if the measured object has a high reflectivity, the measured 
temperature will be mainly from the reflexions of the hot machine parts, not only from the measuring ob-
ject itself. In such a case the reflected radiation has to be blocked by suitable equipment. 

 

The spectral range of the ISR 50-LO is sensitive to bulb light or daylight (not for neon lamp light or dif-
fuse daylight). The influence of such external light must be avoided for an accurate measurement.

Instrument settings 

 
The pyrometers are equipped with a wide range of settings for optimal adaptation to the required measuring 
condition and for getting the correct measuring temperature. 
All instrument settings can be done directly at the instrument or via serial interface and software InfraWin 
(see section 10, Settings via interface and software, user of an own communication software find all inter-
face commands on section 14, Data format UPP

®

).

Settings at the instrument 

The LC-display as well as the push buttons  for 
displaying and setting of the parameters are 
found inside the converter. The pyrometer is 
opened by 4 allen screws. 
 

 

 

Note:  

Only operate the device for a prolonged period of time when it is closed! After setting 
the parameters, replace the housing cover immediately to prevent dirt from entering 
the device and to meet the electromagnetic requirements (EMV). 

 

 1   PAR: With 

the 

PAR button all available parame-

ters are displayed in the following descrip-
tion (section 9). Pushing the button again 
changes the display to the next parameter 
and on the display a corresponding short 
form is displayed. 

 2  

 

 

With the arrow keys all parameter settings 
can be displayed. They are active after 
pushing the PAR button. Pushing the button 
longer changes the settings in fast mode.

 3   ESC / ENT: Pushing the ESC button changes the pyrometer to measuring mode. If a parameter is 

changed with the arrow keys the indication of the ESC button changes to ENT. Pressing 
the button again confirms the value into the pyrometer. Changing the parameters again by 
pushing the PAR button doesn’t confirm this value in the pyrometer. If no button is pressed 
for 30 s the pyrometer changes to  the temperature indication without accepting the 
changed value. 

 

 

Note:  

If the pyrometer is connected to a PC via interface and the software InfraWin is 
opened with the setting window „Pyrometer Parameters“, changing of settings on the 
pyrometer is blocked.
