The use of infrared thermography for predictive maintenance (PdM) and condition based monitoring (CBM) is now widely recognized. The benefits of infrared thermography coupled with lower equipment costs have led to a greater public awareness of common applications. Research continues to broaden the applications of thermography. Advances in equipment now allow thermographers to routinely perform tasks that could only be dreamed of as little as ten years ago.

Common applications for infrared thermography now include electrical and mechanical systems, building envelopes, insulated roofs, petrochemical processes, transportation and medicine. Before embarking upon a project, a thermographer needs to consider and understand how each of these factors will influence the final results and plan their work accordingly.

Having the correct time associated with your imagery is important for several reasons. With correctly dated imagery, it is possible to:

• Accurately document when an inspection was performed
• Easily store and uniquely reference image files
• Record the duration of a thermal event

It is always good practice to consciously check your imager’s clock each time you start your imager and make any necessary adjustments. Be certain to check the clock periodically during each inspection and whenever the imager is restarted, such as after a battery change or power interruption.

If your imager frequently displays incorrect time, it may be indicative of a defective or dead internal battery. To avoid this problem, arrange for replacement of internal clock batteries whenever you have your imager serviced or repaired.
