1
Remove the battery from the battery
compartment of the camera.
2
Plug the mains charging unit to a mains circuit
and plug the jack from the charging unit into
the battery station.
3
Insert the battery into the battery charging
compartment on the battery charging station.
A green light will show that the unit has
power. The charging light on the charging unit
will flash amber whilst the charger assesses
the charge held on the battery. Following this
a solid amber light will be displayed showing
that the unit is charging.
4
When the amber light is no longer displayed,
the battery is fully charged.
5
Remove the battery from the charging
compartment.
6
Insert the battery pack into the camera paying
careful attention to the orientation of the pack.
1
Check the contents of your Infrared Camera.
The shipping case should include the
following items:
• TC7000/TC7150 Thermal Imaging Camera
• USB Communication Wand
• Manual Pack
• Certificate of Conformity
• Neck Strap
• Rechargeable Battery Pack
• Lens Cleaner
• Wrist Strap
• Access key
• Battery Charging Station and Mains
Charging unit
2
Please ensure that you fully charge the
battery prior to use. The battery is charged
using the docking station supplied.
(See page 7.)
3
Before using Infrared Camera consider the
objects that you are going to image. Will
you use comparative thermography (simply
looking for temperature difference) or are
you going to attempt to make an accurate
temperature measurement?
4
For comparative thermography, do not
amend the emissivity setting and leave this
constant every time you carry out imaging.
Temperature differences over time will then
be valid although the ambient temperature
may have changed as well as the electrical
or mechanical load of the object.
5
For accurate thermal measurement the
emissivity of the object will need to be
considered and the camera emissivity
setting corrected.
In addition background and reflected ambient
will need to be considered as well as thermal
and solar reflection and relative humidity.

FOCUS
CAPTURING A
THERMAL IMAGE
• Correct focus is critical in producing an
effective thermal image. Slowly rotate the
knurled orange Focus Ring on the front of
the lens until the object is clearly in view.
You may find that the best focus is easier
to achieve using a grey scale palette. Make
sure that you focus on the object to be
measured rather than the background.
• Switch on the Infrared Camera by pressing
and holding the power switch for at least 3
seconds.
• Ensure auto Level/Span is enabled.
(See Settings section on P.13)
• Ensure that camera is correctly focused.
• You should now see a high quality thermal
image and be able to discern small spatial
and temperature differences.
• Spots (crosshairs) can be moved by using
the joystick. The temperature at that point
is displayed on the top left of the display.
When the crosshair is highlighted, pressing
and holding the joystick will allow the
emissivity of that spot only to be changed.

Document Reference TC7000/TC7150UM Rev. B 9

• Pressing the joystick again will highlight
each spot in turn. This is followed by the
option for the Infrared Camera to scan
for an RFID tag. Place the top front of the
camera within 5 cm of an RFID tag and
press/hold the joystick again. The RFID tag
information will be displayed and can be
edited. (See detailed RFID Section on P.11)
MENU SELECTION
• All other camera settings and features are
selected through the menu button. Press this
once to display 6 icons.
• When the NUC icon is highlighted one press
of the joystick will perform a manual Non
Uniformity Correction (NUC). This should
not be required in normal use as the NUC
is carried out automatically when required.
A distinct click will be heard when the
NUC is performed and the thermal image
will be refreshed. A manual NUC may be
required when moving to different ambient
temperatures but very frequent NUC
operation will seriously impact battery life.
• When the analysis icon is highlighted
pressing the joystick in will cycle through
crosshair (spot) selection (0,1,2 or 3),
maximum temperature display (within entire
image), minimum temperature display (within
entire image). (See detailed analysis section
on P.12)
• The settings icon enables the user to select
or deselect all of the display settings. (See
detailed Settings section on P.13)
• The parameters icon allows measurement
parameters to be altered. These include
ambient temperature, reflected temperature,
relative humidity and target distance. Note
that emmisivity adjustment is selected
individually at each spot measurement. (See
detailed parameters section on P.14)
• The clock icon enables setting of all time
and date information.
• The info icon displays camera serial number,
internal memory used, remaining internal
memory and battery capacity.

RFID ANALYSIS
• When an RFID tag is located an RFID details
menu will be displayed which shows the
hexadecimal identification of the RFID tag.
• It is recommended that an alias is then
added for future identification the tag
location . Use the joystick to highlight the
alias section (complete with selecting OK)
and then input a simple description through
the qwerty options (complete with selecting
OK - this can be edited later in CorDEX
CONNECT)
• Select whether the RFID Tag is built into
a CorDEX IR window (IW2000, IW3000,
IW4000) or if it is a stand alone tag (NON
CDX).
• With the RFID tag editing complete select
SAVE to store this information for future use.
The analysis menu is split into two sections;
Spots and Isotherms. Selecting Spots enables
live spot measurement mode with three
options.
1
The No. spots icon allows choice of 0, 1, 2 or
3 temperature spots (crosshairs) within the
display that will update in real time
2
The Hi icon enables and disables display of
maximum temperature within the image as a
red spot (crosshair). This temperature will be
the same as the top of the temperature range
in auto span/level.
3
The Lo icon enables and disables display of
minimum temperature within the image as a
blue spot (crosshair) This temperature will be
the same as the bottom of the temperature
range in auto span/level.
Selecting Isotherms enables live isotherm
analysis.
1
There are two options; Upper and Lower,
each option having a colour and temperature
selection.
2
Selecting “Upper” will saturate any temperature
greater than the temperature selected below
this option with colour selected below this
option.
3
Selecting “Lower” will saturate any temperature
lower than the temperature selected below this
option with colour selected below this option.

LEVEL/SPAN STORING AND
ANALYSING IMAGES
• Two settings are fundamental to obtaining
an effective thermal image, the first is clear
focus and the second is the correct thermal
range which is adjusted by Level and Span
Settings.
• With Auto Level and Span enabled in the
Settings Menu the range is automatically
adjusted to display both the hottest and
coldest temperature within the field of view.
• When more sensitivity is required level and
span must be set manually by disabling
auto level/span in the Settings Menu and
using the L+/Land S+/S- buttons on the
rear of the camera. Start by increasing the
span (sensitivity) to the required setting and
then increase or decrease the level (range)
so that the object is visible at the required
sensitivity.
• The Image Save Button on top of the
handgrip is used to store images (except
when periodic save is enabled).
• When you want to save an image, press the
Image Save Button and a Save Image menu
will appear. Use the joystick to select yes
and press joystick to save.
• If RFID scan is enabled in the Settings Menu
you will be asked to scan an RFID tag to link
the saved image to a location.
• If text annotation is enabled in the Settings
Menu you will be asked to select one of 4
pre-programmed text comments. After this
the image is stored in the camera memory.
• If voice annotation is enabled in the Settings
Menu you will be asked to record your
message. Press the joystick on the Record
Button, speak (maximum ten seconds) and
then press the joystick on the Stop Button
to finish.
• To review saved images within the camera
press VIEW on the rear of the camera and
use the joystick to select the image required.
Pressing the joystick will display the stored
image full size on the camera display
showing all of the parameters displayed
when the image was saved. Moving the
joystick up and down will change the display
colour palette.
Moving a spot and setting its emissivity
There are three measurement spot options
made available within your camera. Each
spot has an individual measurement function
as the target material between spots maybe
different. To access and adjust the individual
spot location and emissivity;
1.
In the live view mode, momentarily press the
Joystick until the spot you want to adjust is
highlighted in green at the top of the display.
2.
To move the spot to the desired location on the
screen use the joystick.
PARAMETERS CONTINUED
3.
When the spot is located in the correct
position, press and hold the joystick for 3
second and the emissivity setting will appear
in grey adjacent to the spot. To alter the Spot
emissivity move the joystick left and right.
The value can be set from 0.3 – 1.0 in 0.01
increments. To accept the adjustment, press
the joystick in once more.

TEN SUGGESTIONS FOR
THERMOGRAPHY BEST PRACTICE
1
Ensure that the electrical or mechanical
system you are imaging is running fully loaded
to highlight thermal anomalies. A fully loaded
system will generate higher temperature
differential making it simpler to identify
problems.
2
Ensure your image is in focus – this is
important not only for image clarity but also
accurate temperature discrimination and
measurement. Focus should always be set to
the object being measured even if this means
that a surrounding area may be out of focus.
3
If working in a Zone 1 Hazardous area, ensure
that your thermal imaging camera is marked
with the appropriate certification to avoid
risk of explosion. Employers are required
to identify hazardous areas clearly for both
employees and contractors.
4
If you are looking for temperatures above
or below a temperature threshold, use an
isotherm or maximum temperature within an
area feature to clearly highlight any excess.
These features save time and increase
awareness as surveys can take several
hours where fatigue could cause an important
anomaly to be overlooked.
5
Observe a scene from different angles to
minimise thermal reflection as an unusual
warm area could just be your own thermal
reflection. Minimise solar reflection on display
screens outdoors by changing your stance or
swivelling the lens to eliminate reflection.
6
Always consider the object emissivity first
if you want to come close to an accurate
temperature measurement, but remember
that regular comparative thermography will
also show temperature changes leading to
potential failure.
7
For comparative thermography, ensure that
thermal camera settings and especially
emissivity remain consistent. Ideally system
load should also be similar although this is
often impractical.
8
Use infrared windows to image electrical
switchgear under full load in safety. Never
open cabinet doors or override protection
devices, this will put you at serious risk of
injury from arc flash. Even a change of airflow
or dust and debris being dislodged can trigger
an arc flash incident.
