5.2 Overview

Portable infrared thermometers measure surface temperatures without touching the surface. They
collect the infrared energy radiated by a target and compute its surface temperature. They also
compute the running average, and maximum/minimum/differential temperatures and present them
on a digital display in either degrees Celsius or Fahrenheit. The instrument is battery-powered or can
be powered by a computer's USB interface. Internal memory circuits store temperature data for later
recall, and a data-logging feature allows users to store and multiple temperature, emissivity, and
alarm readings (valuable for comparative analysis).
The following figure shows the features of the portable infrared thermometer.

Point the instrument at the object the user wants to measure (as perpendicular as possible to
the object) and pull the trigger. The current temperature (in °C or °F), emissivity value, and
maximum and minimum measured temperature are displayed.
Change the emissivity value to correspond to the targeted material by pressing the <F1> key
twice to show the target material table. Press the ▲ and ▼ buttons to select the target material.
For complete definitions of the instrument's modes and functions, and for full
explanation of operation, refer to the later sections.
