Thermal Imager / English
6-4-2. Histgram mode and Auto mode
• Auto mode: level and span are decided by the thermal image of minimum temperature and
maximum temperature. The relationship between temperature and color is linear.
• Histgram mode: the thermal image is enhanced by histogram algorithm, The relationship
between temperature and color is not linear. Some part of the image is enhanced.
6-5. Parameter menu
• In main menu, press "Left/Right" button, highlight "Parameter ".
• Short Press the "OK|ESC" button, the Parameter submenu will popup. Long Press the
"OK|ESC" button to exit the Parameter settingmenu.
6-5-1. Ambient temperature
composation
Ambient temperature will affect the
measurement of the thermal imager,
it can be composite from 0 degree to
50 degree.

6-5-2. Reflective temperature
The reflective temperature is important for radiometric temperature measurement. Thermal
Imager has temperature compensation for reflective temperature. To get more accurate
temperature measurement, accurately set the reflective temperature. In most cases, the
reflected temperature is identical to the ambient temperature. Only when objects with strong
emissions with much higher temperature are in the proximity of the object being measured,
the reflected temperature must set.
6-5-3. Atmospheric humidity
Water droplets in the air can absorb infrared rays. The wet air can affect the measurement of
the temperature's accurate, the compensation humidity can be set from 10%~100%.
6-5-4. Delta temperature compesation
In delta temperature,the value of the delta temperature will affect the measurment directly.
6-5-5. Distance
There are many substances in the air that can absorb infrared rays. So the infrared ray of
the object will decaied as the distance increase. The distance can be setted from 2meter to
1000meters.
6-5-6. Emissivity
"Emiss" sets object emissivity, the value range is 0.01~1.00;
