measurement
4.3.1.
The measured temperature of the centre of pixel is displayed in the upper left corner of display screen. (fig.4)
4.3.2.
The setting of the radiation coefficient is also displayed in the upper right corner of display screen.
4.3.3.
move the product until the hot spot or cold spot coincides with the centre of the screen.
4.3.4.
move the product to the object whose temperature is higher or lower than the surrounding temperature to get the optimum results.

focal distance
4.4.1.
The Thermal Imaging Camera has a focal distance fixed at 50cm (20in.)
Back light Setting
4.5.
4.5.1.
enter the menu mode, press the "select" key to choose the back light menu, then press the up and down key to adjust the brightness,
the default brightness is 50%.
4.6.
led light
4.6.1.
Press "image capturing" key for 5 seconds to turn on led light to work with the visible camera.
4.7.
colour palette
4.7.1.
"Colour Palette" menu can change the fake colour of the infrared image displayed on the screen or capture (fig.5.)
4.7.2.
A series of colour palettes are available, some being more suitable for certain applications.
4.7.3.
Gray scale palette provides balanced linear colour, this can help to reveal details.
4.7.4.
High contrast palette emphasises the displayed colour, this is more applicable to hot / cold contrast situations. it helps to improve the
colour contrast between hot and cold temperatures.
4.7.5.
iron red and rainbow palettes provide a mixed high contrast Gray scale palette.

4.8.
Temperature of reflective Background
4.8.1.
the background temperature can be set between 0°c and +36°c.
4.8.2.
Set the temperature compensation for reflective background in the option "background"
4.8.3.
Too hot or too cold objects may influence the object or the surface temperature and therefore influence measurement accuracy.
4.8.4.
When the radiation coefficient of the surface of the measured object is low, this phenomenon is obvious. Under many situations, adjust
the temperature of reflective background to get the optimum measured results.
4.9.
marking of Spot Temperature
4.9.1.
Press the menu button to enter the menu mode, then press the up or down key to choose the point temperature tag menu.
4.9.2.
Press the select key and the press the up key to open and close the point temperature tag.
4.9.3.
if turned on the marking spots indicate the hot / cold spots on the screen.
the product displays the temperature in units of °C or °F.
4.10.
unit of Temperature
4.10.1.
4.11.
image mixing
4.11.1.
the mixed image makes the understanding of infrared image becomes easier.(fig.6)
4.11.2.
the camera can capture the visible image of each infrared image to accurately display the temperature distribution of the target
area.
4.11.3.
this feature can help with sharing of the information.
4.11.4.
to use this mixing function, press "left" or "right" key to adjust the mixed image from 0% to 100%.
