Listening to Voice Annotations
To play the voice annotation already stored with an image on the SD memory
card:
1. Perform the steps in the “Reviewing and Deleting Stored Images” section
to select the image on the Imager’s display.
2. Press the softkey labeled Select.
3. Press the softkey labeled Audio.
4. Press the softkey labeled Review.
The saved voice annotation will be replayed through the Imager’s speaker.
Enabling/Disabling Spot Indicators
To enable or disable the hot and cold spot indicators:
1. Press until Spot Temp appears over .
2. Press the softkey labeled Spot Temp.
3. Press the softkey labeled Off to turn the hot spot and cold spot indicators
off or press the softkey labeled On to turn them on.
4. Press the softkey labeled Done to accept the setting.
5. Wait for the main menu to disappear or quickly squeeze and release the
trigger twice in order to return to live view.
Making Accurate Temperature Measurements
All objects on Earth radiate infrared energy. The amount of energy radiated is
based on two primary factors: the surface temperature of the object and the
emissivity of the object's surface. The Imager detects the infrared energy from
an object and uses this information to estimate the temperature of the object.
Most of the objects measured such as painted metal, wood, water, skin, and
cloth are very efficient at radiating energy and it is easy to get very accurate
measurements.
For surfaces that are efficient at radiating energy (high emissivity), the
emissivity factor is estimated to be 95% (or 0.95). This estimate works for
most purposes. This simplification does not work however, on shiny surfaces
or unpainted metals. These materials are not efficient at radiating energy and
are classified as having low emissivity. To accurately obtain a temperature
