Introduction
The VT02 (the Product) is a Visual IR Thermometer that combines surface
temperature measurement together with a real-time thermal image.
The thermal image removes the time necessary for component-by-component
measurement associated with traditional spot radiometers. Potential issues are
clearly shown on the color LCD display to help the user quickly and accurately
position the center-point measurement cursor and measure the temperature.
To aid identification, the Product includes a visual camera. Images can be
blended from full thermal to full visual as necessary. Both thermal and visual
images can be saved to the removable memory card. Images can be recalled or
saved to a PC for report generation and to print.
The VT02 is easy to use. Turn on and within seconds it is ready to test. The
Product is ideal for electricians and maintenance technicians and can be used
to find areas of concern quickly.
Several features increase the accuracy and usability of the Product:
• Adjustable emissivity and reflected background compensation
improves measurement accuracy on semi-reflective surfaces
• Hot and cold spot temperature markers that guide the user to the
hottest and coldest regions in the thermal image
• Selectable color palettes

Power On and Off
To turn on the Product, push and hold E for 2 seconds. A start-up screen
shows on the display and an indicator bar shows the status, see Figure 1. The
indication bar increases on power up and decreases on power down. After the
start-up screen, the Product is ready to use. To turn off the Product, push and
hold E for 2 seconds.
The Auto Off feature turns off the Product after 10 minutes of inactivity.

Note
All visual IR thermometers need sufficient warm-up time for the most
accurate temperature measurements and best image quality. This time
can often vary by model and by environmental conditions. Although
most visual IR thermometers are fully warmed up in 3 to 5 minutes, it
is always best to wait a minimum of 10 minutes if the most accurate
temperature measurement is very important to your application.
When you move a visual IR thermometer between environments with
large differences in ambient temperature, more adjustment time can
be required.
For the first time use, or when the batteries are removed for more than a few
hours, the Date and Time menu opens. See page 13 for more information about
how to set the date and time.

Focus
The Product is a fixed focus visual IR thermometer that operates from 50 cm
(20 in).
Button Operations
Two functions are accessed directly from the buttons: Blending/Capture and
Save. The arrow buttons are used for menu navigation.
Image Blending
Image blending makes it easier to understand infrared images through the use
of an aligned visible image and infrared image. The Product captures a visible
image with each infrared image to exactly show the target area and more
effectively share it with others.
To use the blending function:
1. Push E until shows in the bottom left-hand corner of the screen.
2. Use D/C to adjust the blending from 0 % to 100 %.
The blend options are shown in Figure 2.

Capture and Save
The Product saves up to 10,000 images on the Micro SD card.
To capture the image and save it to memory:
1. Push E until shows in the bottom right-hand corner of the
screen.
2. Point the Product at the object or area of interest.
3. Pull the trigger to capture the image.

Review Memory
The Memory mode lets you view the stored images. You can also delete
images in this menu.
1. Push F to open the Memory mode.
2. Push D/C to scroll through and review the stored images.
3. Push F to delete image.
Emissivity
The emissivity is adjustable in 0.01 steps from 0.10 to 01.00. The default value
is set at 0.95.
The correct emissivity values are important for you to make the most accurate
temperature measurements. Emissivity of a surface can have a large effect on
the apparent temperatures that the Product observes. Understanding the
emissivity of the inspection surface can, but not always, allow you to obtain
more accurate temperature measurements.
Temperature Measurement
All objects radiate infrared energy. The quantity of energy radiated is based on
the actual surface temperature and the surface emissivity of the object. The
Product senses the infrared energy from the surface of the object and uses this
data to calculate an estimated temperature value. Many common objects and
materials such as painted metal, wood, water, skin, and cloth are very good at
radiating energy and it is easy to get relatively accurate measurements. For
surfaces that are good at radiating energy (high emissivity), the emissivity
factor is ≥90 % (0.90). This simplification does not work on shiny surfaces or
unpainted metals as they have an emissivity of <60 % (0.60). These materials
are not good at radiating energy and are classified as low emissivity. To more
accurately measure materials with a low emissivity, an emissivity correction is
necessary. Adjustment to the emissivity value will usually allow the Product to
calculate a more accurate estimate of the actual temperature.
Visual IR Thermometer
Menu Functions
12
Note
Surfaces with an emissivity <0.60 make reliable and consistent
determination of actual temperatures problematic. The lower the
emissivity, the more potential error is associated with the temperature
measurement calculations of the Product, even when emissivity and
reflected background adjustments are attempted and performed
properly.
W Warning
To prevent personal injury, see emissivity information for actual
temperatures. Reflective objects result in lower than actual
temperature measurements. These objects pose a burn hazard.
Go to http://www.fluke.com/Fluke-Thermal-Imaging-and-Thermal-Imagers for
more information on emissivity and how to get the most accurate temperature
measurements.
Color Palette
The Palette menu changes the false-color presentation of the infrared images
that are on the display or captured. A variety of palettes are available. Some
palettes are more suitable for specific applications and are set as required.
Grayscale Palettes offer an equal, linear presentation of colors that allow for
best presentation of detail.
The High Contrast palette offers a weighted presentation of colors. This palette
is best in situations with high thermal contrast for increased color contrast
between the high temperatures and low temperatures.
The Ironbow and Rainbow palettes offer a mixture of the High Contrast and
Grayscale palettes.

Reflected Background Temperature
The background temperature can be set between 0 °C and +36 °C.
Compensation for reflected background temperature is set in the Background
tab. Very hot objects or very cold objects can affect the apparent temperature
and measurement accuracy of the target or object of interest, especially when
surface emissivity is low. Adjustment of the reflected background temperature
can make the temperature measurement better in many situations. For more
information, see Emissivity on page 11.
Spot Temperature Markers
The spot temperature markers turn on and off. When turned on, the marker is
an indication of a hot or cold spot in the scene that may require additional
evaluation. When turned off, the user is able to concentrate on the single
measurement pixel.
Temperature Units
The Product displays temperatures in °C or °F.
Date and Time
In the Clock menu the user can set the time and the date.
Push F to select the Clock.

Measurements
The temperature measurement of the center pixel is shown at the top of the
display. The emissivity setting also shows at the top of the display. When the
hot/cold temperature markers are turned on, move the Product until the hot or
cold spot coincides with the middle measurement pixel. Point the Product at an
object that is likely to be hotter or colder than its surroundings for best results.
The value of the hot/cold point shows at the top of the screen.
