Display functions / Setting keys

Additionally to the temperature measurement the  

THERMOSIGHT HT

  provides some more func-

tions which are necessary for a correct measurement and usefully enlarging the functionality of the 
pyrometer.



Indication °C or °F: 

indicates the temperature in °C or °F.

Temperature display:

 shows the actual or stored temperature value. 

Parameter / function:

 selecting a parameter or a measuring function for indication or changing a 

corresponding short form will be displayed.

Parameter value / function value:

 indicates the value of the adjusted parameters or the tempera-

ture of the selected measuring function.

PAR key:

 Repeated pushing of the PAR

 

key displays all available parameters (as EMI, HI, INT, 

C/F) or additional measuring functions in the following sequence mentioned below. Parameters are 
part of the basic settings of the pyrometer. They are only displayed during adjustment. Measuring 
functions are displayed additionally to the measuring temperature (MAX, MIN, AVG, DIF), can give 
an acoustic signal (HI) or can be used for data analysis (RCL). Selected measuring functions are 
stored when the pyrometer is switched off and will be activated by restarting the instrument.
