Tech Tip: Do You Have the Correct Time?

Most modern thermal imagers have the ability to record the time and date along with thermal images. Taking a moment to ensure that the correct time and date are displayed on your imager before you begin your inspection can help to avoid wasted time and the collection of inaccurate data.
Having the correct time associated with your imagery is important for several reasons. With correctly time-stamped 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.
