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 component-
by-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®software.
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

Power On and Off
To turn on the Product, push and hold for 2 seconds. A start-up screen
shows on the display and an indicator bar shows the status, see Figure 1. The
indicator 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 for 2 seconds.
The LCD backlight (VT04A and VT04) turns off to save battery power if a button
is not pushed for more than 2 minutes. You can push any button to turn on the
backlight before the auto off time is exceeded. This feature is disabled in Alarm
mode.
The Auto Off (VT04A and VT04) feature turns off the Product after a selected
time interval. The default setting is 10 minutes and is user-selectable as 5, 10,
15, or 20 minutes of inactivity. This feature is disabled in Alarm mode.

Figure 1. Start-Up Screen and Status Indicator
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.

Rechargeable Battery
The VT04 has a rechargeable Li-ion battery.
Note
New batteries are not fully charged. Two to ten normal
charging/discharging cycles may be required before the battery
charges to its maximum capacity.
Before using the VT04 for the first time, charge the battery:
1. Plug the ac power supply into an ac wall outlet.
2. Connect the micro-USB connector to the VT04. See Figure 2.
While the battery is charging, shows on the display and the status
LED is red. When charged, shows on the display and the status LED
is green. The typical charge time from 100 % discharged to 100 % charged
is 5 to 6 hours.
Note
Make sure the Product is near room temperature before you connect it
to the charger. See the charging temperature specification. Do not
charge in hot or cold places. Charging in extreme temperatures
reduces the battery pack’s ability to hold a charge.

Button Operation
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 heat maps through the
use of an aligned visible image and infrared heat map. The Product captures a
visible image with each infrared heat map to exactly show the target area and
more effectively share it with others.
To use the blending function, push /to adjust the blending from 0 % to
100 %. The blend options are shown in Figure 3.

Visual Image Alignment Control
The heat map overlay and the visual camera are positioned vertically in the VT
Series. This vertical parallax will change with distance to your object. To correct
the parallax for a near or far distance, you have a visual image alignment
control. See Figure 4.
To toggle the control between a near object or far object:
1. Push NEAR () for a measurement distance from 15 cm to 23 cm (6 in to
9 in).
2. Push FAR () or a measurement distance further than 23 cm/9 in.
The Near or Far icon shows in the upper left corner of the display.
