Glossary

Term	Definition
160x120	The number of pixels (picture elements or dots) in a saved thermal image. Each pixel has a
	temperature associated with it. Each thermal image is 160 pixels wide by 120 pixels high.
accuracy	The guaranteed correctness of a temperature reading. For example, ± (2° or 2% of reading),
	whichever is greater.
ambient temperature	The surrounding background or environmental temperature around the Thermal Imager.
blackbody	A blackbody absorbs all thermal radiation striking it and emits all of it back. This means that a
	perfect blackbody has an emissivity of exactly 1. Surfaces that are closest to a blackbody in
	real world applications are flat black paint and black electrical tape. (See “emissivity.”)
battery fuel gauge	A symbol on the display in the shape of a battery, with a bargraph indicating the level of
	remaining charge. The more white bars showing, the more charge remaining.
brightness level	Refers to the display brightness, which you can adjust in the Setup Menu.
calibrate, calibration	Comparing a measurement device’s readings to a reference standard. Calibration usually
	involves adjustment to correct for errors, but not always. In the Thermal Imager, an internal
	reference standard calibrates the unit once per minute. Also see “Calibration interval.”
calibration interval	The period of time after production or re-calibration that a measurement device’s
	specifications are valid --1 year for the Thermal Imager. After 1 year, contact a MILWAUKEE
	Service Center for factory calibration to renew the calibration cycle.
camera	Refers to the built-in visual image digital camera.
camera lens	Refers to the front optical element in the built-in visual digital image camera, located between
	the flashlight LEDs below the Thermal Imager lens. This is a fixed-focus lens – no adjustment
	required.
