# 

• This short instruction is describing, how can you modify the thermal settings, in order to let objects with higher temperature visible and the others invisible.  
• Put the thermal camera faced to a human face, approx. 1 meter away from the face.

• Make sure the camera is set to factory default.  
• Go to the menu: ”Setup” → “Image Control” → “Thermal Sensor Settings”

• Set “Temperature Control Windows” to “Custom Windows”.  
• Open the camera live view.  
• Draw a rectangle, which covers the human face, the same way as you define a video motion window.

• Go back to the menu “Thermal Sensor Settings”.  
• Press button “Add Rectangle” to add this window as reference window.  
• Set “Show Window” to “Histogram”.

• The min. and max. thermal value will be displayed in the histogram, these values are the min. and max. thermal value inside the reference window correspondence.

• Note the found max. value in last step, e.g. “247”.  
• Go back to the menu “Thermal Sensor Settings”.  
• Set “Automatic adjustment” to “Disable”.  
• Enter the found max.value from last step in the field of “Minimum Thermal Value”The min. e.g.”247”.  
• Enter a value approx. 10 above the minimum in the field of “Maximum Thermal Value”, e.g. “257”.  
• By this way you would find roughly the values for min. and max.  
• Then you can adjust them iteratively, to let the higher temperature visible and the other invisible.
