Operating instructions CellaTemp PX 4x 5x 6x

9  Setup

The pyrometer uses the intensity of infrared radiation for the non-contact tempera-

ture measurement�
The pyrometer PX can be used as spectral or two-colour pyrometer� 
When delivered, the pyrometer is configured for the two-colour measurement�

9.1  Setup two-clour mode

The two-colour measuring method detects the infrared radiation at two different 

wavelengths and calculates the quotient from the values obtained� This measure-

ment method is suitable for measurements of targets that are partially obscured 

(either intermittently or permanently) by other objects, openings, screens or view-

ing windows that reduce energy, and by dirt, smoke, or steam in the atmosphere� 

The two color mode can also be used on targets that do not completely fill the 

target spot, provided the background is much cooler than the target�

Setting the emissivity ratio (two color mode) 

The difference between measured temperature and true temperature can be 

compensated by changing the emissivity ratio� Make this adjustment for selective 

interferences or when the emissivity for wavelength 1 and wavelength 2 will be 

different because of the material that is being measured�
• Emissivity ratio [

qu

] → [

q.ESP

] = 80 - 120 %

 

►

Press [

˄ 

or 

˅]

 

> The value of the selected emissivity ratio is displayed, for example [

100.0

] 

 

► Press [˄ or ˅] until the desired emissivity will show

 

►

Press [Enter] or wait for 3 seconds

 

> The current temperature value is displayed and the new emissivity coefficient 

is stored

When simultaneously pressing the MODE key, the display shows the 

current measuring temperature while the emissivity coefficient continues to 

be adjusted in the background� This is an easy way to determine the emis-

sivity ratio when the object temperature is known� The changed values are 

directly adopted�
