Abstract
A handheld instrument that accomplishes infrared (IR) temperature measurement and non-contact electrical current measurement. The instrument has a case, a current-sensing device coupled to the case and operable to be placed around a conductor, for generating an output signal based on the current flowing through the conductor, and an IR detector carried by the case, for sensing IR energy emitted from a surface being measured along a sensing axis that extends from the case, and generating an IR output signal. Sensed IR energy is converted to a temperature value, and the output signal from the current-sensing device is converted to at least a measured current value. There is a display device in the case, for displaying instrument measurements to the user.
