1. 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 mounted in a mount that is coupled to and movable relative to the housing, where the mount projects outwardly from the housing, to allow the user to aim the temperature sensing device, the temperature sensing device comprising an infrared sensor coupled to the housing, having an output related to sensed temperature; and
circuitry contained in the housing for processing both the multimeter outputs and the temperature sensing device output, and transmitting the processed output to the output display, in which the circuitry determines the sensed temperature based on the output of the temperature sensing device using a fixed emissivity.

Abstract
A multimeter with non-contact temperature measurement capability. The multimeter is contained in a housing, and has outputs relating to measured electrical parameters. There is also an output display contained in the housing, for displaying results to a user. A non-contact optically-based temperature sensing device is coupled to the housing, and has an output related to sensed temperature. Circuitry contained in the housing processes both the multimeter outputs and the temperature sensing device output, and transmits the processed output to the output display.
