Check the contents of your Infrared Camera.
The shipping case should include the
following items:
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.
Remove the battery from the battery
compartment of the camera.
Insert the battery pack into the camera paying
careful attention to the orientation of the pack.

Plug the mains charging unit to a mains circuit
and plug the jack from the charging unit into
the battery station.
Remove battery when the camera is no longer
in use. DO NOT REMOVE BATTERY WHILST IN
HAZARDOUS AREA.

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.

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?

• 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.

TEN SUGGESTIONS FOR
THERMOGRAPHY BEST PRACTICE
1
5
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.
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.
2
6
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.
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.
3
7
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.
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.
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.
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.

TC7000/TC7150 – User Manual
9
Always store images and relate them where
possible to visible images when building a
Report. This makes it easier to pinpoint the
fault for scheduled maintenance. Choose a
reporting software package that makes this
process simple and consider installing RFID
tags to link measurements from different
technologies to one specific location.
10
Report critical items separately in the Report
and draw attention to them clearly – the
whole idea of thermography for preventive
maintenance is to find faults and fix them
before they cause a breakdown and loss
of production or uptime. Choose a report
software package that creates a scheduled
job sheet to pass straight to the maintenance
engineer.
