Before You Start

Power On and Off
To turn on or turn off the Imager, push and hold
for two
seconds. The Imager has Power Save and Auto Off
features. For more information about how to set these
features, see Settings Menu.
Note
All thermal imagers 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 imagers are fully warmed up in 3-5
minutes, it is always best to wait a minimum of 10
minutes if the most accurate temperature
measurement is important to your application.
When you move the Imager between
environments with large differences in ambient
temperature, more adjustment time can be
required.
Focus
The Imager uses the LaserSharp™ Auto Focus System
and an advanced manual focus system. Correct focus is
important in all imaging applications. Correct focus makes
sure that the infrared energy is correctly directed onto the
pixels of the detector. Without correct focus, the thermal
image can be blurry and the radiometric data may be
inaccurate. Out-of-focus infrared images are frequently
unusable or of little value.
The Fluke LaserSharp Auto Focus System uses a
precision-adjusted and aligned laser pointer to indicate the
area of focus. To focus with the LaserSharp Auto Focus
System, depress the large black button (see Table ). Aim
the laser pointer at the target. When satisfied with the
location of the laser pointer, release the button. The
system automatically focuses on the precise point where
the laser was aimed.
Note
You can enable and disable the LaserSharp
Auto Focus System.
The laser pointer is aligned parallel to the
infrared lens. If using AutoBlend Mode, the
laser pointer dot will always be positioned just
above the center point marker on the LCD.
However, it is easier to use your eyes to locate
the visible laser pointer on the target.
To focus with the advanced manual focus system, place
finger on the electronically-driven focus wheel control and
rotate the control until the target is in proper focus.
Note
The advanced manual focus can be used as a
manual override of the LaserSharp™ Auto Focus
System.
