All imagers use an uncooled focal plane infrared detector, and display the
thermal image as a multi-color image with user selectable color palette,
sensitivity and span. On Inspectors the image may be stored in the SD card
and subsequently transferred to a PC for analysis and report generation as
desired.

[1] Power key
Press and hold the Power Key for > 3 seconds to power on/off the camera.
! Note: After powering off, please wait ten seconds before powering the
camera on again.
[2] Select/Auto key (Marked “A”)
The “A” or attribute button performs 2 functions.
a) The first function is modification of selected functions. It is obtained
by a quick press and release (less than 2 seconds), that will select
enabled functions to modify their parameters. Subsequent presses will
“scroll” through the available functions. The selected function will be
highlighted in yellow. The functions include:
•Measurement Cursors
Cursors - pressing the arrow keys will move their position. Pressing the
Menu key will display the attribute box. Pressing the C key will delete the
selected parameter.
•Color Palette
Pressing the left or right arrows will scroll through the available color
palettes, displaying their name above the palette. The selected palette
will become active after about 3 seconds of selecting it and will be set as
the default power on palette.
•Level/Span values
Pressing the left or right arrow will reduce or increase the Span and
pressing the up or down arrow will increase or reduce the Level. If the
unit is in Automatic mode, modifying any of these parameters will select
Manual mode.
b) The second function performed is to force an internal calibration cycle.
This is performed by pressing and holding the A key for 5 seconds or

12
more. The camera will perform an auto calibration cycle, indicating
“calibrating”, ensuring the most accurate thermal measurement.
[3] Cancel/Clear key (Marked “C”)
•Pressing and releasing the C key cancels the present operation when in
Menu mode.
•Pressing and releasing the C key when an image is frozen will return to
real-time measurement status.
•When a parameter is selected, such as a measurement cursor, pressing
the C key will delete the highlighted measurement.
[4] Freeze/Save key (Marked “S”)
Used for freezing a thermal image for on screen analysis. Press the key
once to freeze the image. Press C key to return to real time measurement.
The save function is only available on 50 Series Inspectors.
[5] Menu/Confirm key (bar)
Includes Up, Down, Left, Rig t and Menu/Confirm (center) keys.
unction varies with operation mode.
In Menu mode, it is used for menu selection. Up and Down keys are
for same level menu operation. Left and Rig t keys are for additional levels
of menu operation. Confirm key (center) is to activate the menu and
confirm the choice.
In Image mode, press Up or Down key to activate X2 digital zoom.
The screen will display “X2” in the upper left corner. Press Up or Down key
to return to the original image.
In Spot Measurement editing mode (activated immediately after
adding a spot or by selecting via the A key), press the Menu key to display
the attribute box. Press four navigation keys to move the spot location.

13
[6]Trigger/S ortcut key
The trigger key serves as a shortcut to access the following functions:
Laser – Pulling trigger activates laser sight and releasing deactivates it.
Spot – Pulling and releasing trigger adds a measurement spot. Pulling and
releasing trigger again removes the spot.
2.2 Interface

3Getting started
3.1 Battery Installation and Replacement
3.1.1 Inserting battery
Battery compartment is located inside the handle. Turn the cover counter-
clockwise to remove. Remove battery for replacement.
Insert the battery (the battery contacts must face into the battery
compartment).

15
Replace cover and screw down in a clockwise direction.
! CAUTION: Use only original manufacturer replacement battery. Use of
incorrect battery may result in physical or electrical damage to the
instrument due to incorrect voltage or physical size difference.

16
3.1.2 Replacing battery
When battery has approximately 5% charge remaining, the warning will
be displayed and the instrument will turn off in approximately 3 seconds.
Powering off display
3.2 Battery safety and usage
Batteries should be stored in an ambient temperature of -4° (–20°C) to
67.9° (+20°C). Lithium batteries will self-discharge during storage, so
they should be fully charged before storage. Self-discharge may affect
long term battery performance. urthermore, it is recommended that the
battery should be charged in a set time, as below;

17
Ambient temperature of:
-4° (–20°C) to 67.9° (+20°C), once every 6 months
67.9° (+20°C) to 113° (+45°C), once every 3 months
113° (+45°C) to 149° (+60°C), once every month
or optimal Battery Life, the battery should be recharged when it has
greater than 50% charge remaining.
The ambient temperature for charging should be 32° (0°C) to 104°
(+40°C). If under 32° (0°C), the battery capacity will be diminished; if
over 104° (+40°C), the battery may overheat, resulting in permanent
damage.
!
!!
!WARNING:
!
!!
!Never disassemble, incinerate or puncture battery
!
!!
!Never short circuit the battery
!
!!
!Keep battery dry
!
!!
!Keep out of reach of children
!
!!
!Always dispose of battery in accordance with local, state and federal
regulations
3.3 Quick access
3.3.1 Capture an image
After installing the battery, press and hold the power key (≥3
seconds) until the display comes on. After approximately 50 seconds,
the power on routine will finish and the camera will start its
measurements.
Remove the lens cap and aim at the target. Adjust the focus for the
clearest target thermal image. ! NOTE: ailure to properly focus the
camera will result in increased measurement error.

18
3.3.2 Temperature measurement
If no measurement cursors are on the screen, add a measurement
spot, by pressing MENU and selecting Measurement. Press
CONFIRM and scroll left or right to select the proper measurement
parameter. Aim the cursor indicator onto the target object on the
screen. The temperature will be displayed in the upper right corner of
the screen. or highest accuracy measurements, force a calibration
cycle by pressing the A key for 5 seconds until “Calibrating” appears
in upper left portion of display.
If you want to measure the current thermal image in detail, press S
key to freeze the image for on-screen analysis.
If the target object’s temperature is lower or higher than the limits of
the camera, it will display <XXX° or >XXX° with XXX being the min
or max temperature of the selected range.
To modify the measurements attributes, select the measurement
parameter, and then press the Confirm key. The screen will display
the settings dialog box. The below figure shows the spot settings
window.
Spot settings include emissivity and reference temperature. When
Set Ref is set as Yes, the displayed values of other measurements
will be their delta from this measurement. Setting a specific
measurement cursor as a reference will change the reference for all
measurements.

3.3.3 Freeze image
Press S key to freeze the image and press “Cancel” to exit the
operation.
3.3.4 Viewing stored Images
