this as the Reflected Temperature entered
into the thermal imager.
6. Remove the foil from in front of the surface to
be measured. Enter an appropriate emissivity
for the surface to the be measured and take
temperature measurement.
Setting The RTC
1. Select the Emissivity function.
2. Move the joystick to the right until RTC is se-
lected. Manually set desired value and press
OK.
Setting -Assist
-markers and the -Assist function of the Ther-
mal Imager can be used to automatically set the
emissivity and RTC. RTC can always be set.
Emissivity can only be automatically set if the sur-
face temperature is more than 2°C different than
the reflected temperature. -markers can be used
on surfaces that have a consistent temperature of
less than 176°F (80°C) and a minimum size of at
least 4.75" x 4" (12 cm x 10 cm). Do not reuse -
markers.
1. Affix -marker to the center of the surface and
allow -marker and object temperature to
equalize for at least 30 seconds.
2. Select the Emissivity function.
3. Move the joystick to the right until -Assist is
selected and press OK. The screen will
change to the real image. A white box will ap-
pear on the real image. Place the box around
the -marker (see Figure 12). Thermal imager
should be 20" to 28" (0.5 to 0.7 m) away from
the -marker, and at a 10-30 degree angle.

4. The thermal imager will automatically read the
-marker and populate the emissivity and the

reflected temperature. If emissivity cannot be
read, you will be prompted to manually enter
an emissivity.
5. Press OK key to accept the displayed values.

Selecting Color Palette

A variety of color palettes are supplied to meet
personal preferences. Palettes with greater color
variation may be beneficial when there are larger
temperature differences to better visualize the
temperatures.
This function is only available if the Image type is
set to infrared image.
1. Select the Palette function.
2. Move the joystick up/down to select the re-
quired color palette and then press OK.

Setting Image Type

The display can be switched between infrared
image and real image (digital camera). Model RT-
3 do not have real image function, it has only in-
frared image type.
1. Select the Image type function.
2. Move the joystick up or down and choose be-
tween infrared image or real image view.
3. Press OK key to confirm the selection.
Activating/Disabling The Zoom
(RT-9x only)
1. Move the joystick to the right and open the soft
key menu (quick select button).
2. Move the joystick down and select Zoom.
Then press OK.
3. Press quick select button (
Zoom.
Activating The Differential
Temperature
Differential temperature enables the temperatures
between two measuring points to be calculated
and shown in the status bar.
1. Open Menu.
2. Move the joystick down and select Measure-
ment. Then press OK or move the joystick to
the right.
3. Move the joystick down and select Differential
temperature. Then press OK. The Differential
Temperature menu will appear. The menu will
