Abstract: An electrical continuity test system with a tester and a remote probe. The tester includes circuitry for creating a pulsed current, an output for connection to a local end of a first test conductive element, to inject the pulses into the first test conductive element, an input for connection to a local end of a second test conductive element, and a visual and/or aural indication when the injected pulses are present on the second test conductive element. The remote probe includes an input for connection to a remote end of a first unidentified conductive element, an output for connection to a remote end of a second unidentified conductive element, a first visual and/or aural indication when the first unidentified conductive element is the first test conductive element, and a different visual and/or aural indication when the first unidentified conductive element is the second test conductive element.

Abstract: An anemometer with non-contact temperature measurement capability, including a air velocity meter, contained at least partially in a housing and having outputs relating to measured air velocity parameters including air velocity and ambient temperature, an output display contained in the housing, for displaying measurements to a user, a non-contact optically-based internal temperature sensing device, having an output related to optically sensed IR temperature and circuitry contained in the housing for processing both the air velocity or volume meter output and the temperature sensing device output, and transmitting the processed output to the output display.

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.

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.

Abstract: A handheld instrument that accomplishes non-contact infrared (IR) temperature measurement, and the measurement of movement of an object. The instrument has a case, and a movement-sensing device coupled to the case and operable to be directed toward or placed against an object being measured, for generating an output signal based on the sensed movement. An IR detector, also carried by the case, senses IR energy emitted from a surface being measured along an IR-sensing axis that extends from the case, and generates an IR output signal. The 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. A display device in the case displays instrument measurements to the user.
