Introduction
The VT Series (the Product) are Visual IR Thermometers that combine a
center-point temperature measurement with a blended digital image and heat
map overlay. The thermal image removes the time necessary for componentby-component measurement associated with a traditional spot thermometer
(radiometer). The Product is ideal for electrical, HVAC, and facility maintenance
applications.
The recommended use model is:
1. Scan a broad area with the blended digital image and heat map overlay to
quickly identify temperature anomalies that need more inspection.
2. Use the wide field-of-view to move closer to the target for a temperature
measurement with more detail.
3. Capture both heat map and visual images with a single trigger pull.
4. Create a report with Fluke SmartView
The Product is easy to use. Turn on and within seconds it provides an image
with no training needed. 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 infrared heat map
• Selectable color palettes
• Visual/heat map image alignment
The VT04A and VT04 include these additional features:
• High/Low Temperature Alarms
• Time-Lapse Image Capture
• Auto-Monitor Alarm

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 19 for more information
about how to set the date and time.
Note
All visual IR thermometers need sufficient warm-up time for the most
accurate temperature measurements. 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.

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.
Go to http://www.fluke.com/emissivityexplanation for more information on
emissivity and how to get the most accurate temperature measurements.
Go to http://www.fluke.com/emissivity for a chart that shows emissivity values
of common materials.

Visual IR Thermometer
Menu Functions
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.
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.
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.

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 -10 °C and +100 °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 14.
Hot and Cold Markers
The hot and cold 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.
