Patent ID: 7056012

Claim:
A multimeter with non-contact temperature measurement capability, comprising: a multimeter contained in a housing and having outputs relating to measured electrical parameters; an output display contained in the housing, for displaying results to a user; a non-contact optically-based temperature sensing device comprising an infrared sensor built in to the housing, having an output related to sensed temperature of a surface, and without the capability of adjusting for emissivity of the surface being sensed, the temperature sensing device defining a sense axis that is adjustable relative to the housing, and further comprising a lens, proximate the infrared sensor and mounted in a mount that is coupled to and projects outwardly from the housing, for focusing entering radiation and protecting the infrared sensor, wherein the mount is movable by the user relative to the housing, to allow the user to aim the sense axis; and circuitry contained in the housing for processing both the multimeter outputs and the temperature sensing device output, in which the circuitry determines the sensed temperature based on the output of the temperature sensing device using a fixed emissivity value, the circuitry transmitting the processed output to the output display.
