Introduction
The Fluke VT06/VT08 Visual IR Thermometers (the Product or Meter) are hand-held, infrared
imaging cameras for use in many applications. These applications include equipment
troubleshooting, preventive and predictive maintenance, building diagnostics, and research
and development.
The Meter displays thermal images on a high-visibility, industrial-quality LCD screen. The
Meter can save images to internal memory. You can transfer images and data stored in internal
memory to a PC through a direct USB connection to the PC.
A rugged, rechargeable lithium-ion smart battery provides power to the Meter. Direct ac power
is accessible with the included ac power adapter.

Basic Operation
Power On and Power Off the Product
Before you use the Product for the first time, charge the battery. See Charge Batteries.
To power on the Product, push and hold Pfor 2 seconds.
To power off the Product, push and hold Pfor 2 seconds.
Note
All thermal Meters need sufficient warm-up time for accurate temperature measurements
and best image quality. Warm-up time can vary by model and environmental conditions.
Although most Meters are fully warmed up in 3 minutes to 5 minutes, wait a minimum of
10 minutes if the most accurate temperature measurement is important to your
application. When you move a Meter between environments with large differences in
ambient temperature, allow for additional adjustment time.
Note
If the Product crashes, push and hold Pfor 3 seconds to power off the Product.
Focus
The VT06/VT08 thermometer is a focus-free product, which means that users do not need to do
anything after receiving it. The Product can ensure that the image is clearly set within 0.5 m and
1.2 m.
Laser Pointer
The Meter has a laser pointer. The laser pointer is a sighting aid and is offset from the infrared
camera. As a result, the laser dot does not always represent the exact center of the image.
The laser dot does not appear on infrared-only or PIP images. The laser dot does appear on
visible-only images. You will not be able to see the laser dot in the visible channel of the PIP image
if the dot is obscured by the center point marker graphic.
Pull the Trigger to turn on the laser pointer and release the Trigger to turn off the laser pointer.
Camera mode
The VT08 Meter has the infrared, visible light, and PIP Camera modes, as shown in Figure 1. The
VT06 Meter has only infrared mode.

TempRange
When measuring temperature, you need to use the appropriate temperature range, which
depends on the target temperature. The Meter has these temperature ranges:
-20°Cto150°C(-4°Fto302°F)
100 °C to 400 °C (212 °F to 752 °F)
The Meter can automatically use the appropriate range based on the target temperature if you
set the TempRange to Auto in the Main Menu.
Emissivity
All objects radiate infrared energy. The actual surface temperature and emissivity of the target
affect the quantity of energy radiated. The Meter senses the infrared energy from the surface
of the target and uses the data to calculate an estimated temperature value. Many common
materials such as wood, water, skin, cloth, and painted surfaces, including metal, radiate
energy well and have a high emissivity factor of ≥90 % (or 0.90). The Meter measures
temperatures accurately on targets with a high emissivity.
Shiny surfaces or unpainted metals do not radiate energy well and have a low emissivity factor
of <0.60. For the Meter to calculate a more accurate estimate of the actual temperature of
targets with a low emissivity, adjust the emissivity setting.
WWarning
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.
Set emissivity as a direct value or from a list of emissivity values for some common materials.
Note
Surfaces with an emissivity of <0.60 make it difficult to determine reliable and
consistent actual temperatures. The lower the emissivity, the greater the potential of
error when the Meter calculates the temperature measurement because more of the
energy reaching the camera is specified as background temperature. This is also true
when adjustments to the emissivity and reflected background adjustments are
performed properly.
To adjust emissivity:
1. In the Emissivity submenu, push Wor Xto select which emissivity to use, or select
SelfDefine.
2. If you select SelfDefine, push Oand Wor Xto manually set the emissivity.
3. Push Oagain to save.
4. Push Pto return to the previous menu.

Maintenance
The Product requires minimum maintenance.
Clean the Case
Clean the case with a damp cloth and a weak soap solution. Do not use abrasives, isopropyl
alcohol, or solvents to clean the case.
Lens Care
WCaution
To prevent damage to the infrared lens:
Carefully clean the infrared lens. The lens has a delicate anti-reflective coating.
Do not clean the lens too vigorously because this can damage the anti-reflective
coating.
To clean the lens:
1. Use a pressurized can of air or a dry nitrogen-ion gun, if available, to blow off the particulates
from the lens surface.
2. Soak a lint-free cloth in a commercial lens cleaning liquid that contains alcohol, ethyl alcohol,
or isopropyl alcohol.
3. Squeeze the cloth to remove excess liquid.
4. Wipe the lens surface in one circular motion and discard the cloth.
5. If needed, repeat with a new lint-free cloth.
Battery Care
To get the best performance from the lithium-ion battery:
Do not charge the Product for more than 24 hours because reduced battery life might result.
Charge the Product for at least 2.5 hours every six months for maximum battery life. Without
use, the battery will self-discharge in approximately six months.
