Abstract
A method of HVAC/R test and measurement using a plurality of test and measurement sensor heads, at least one power source and transmitter unit adapted to physically connect with any of the sensor heads and wirelessly transmit data to an external handheld-sized field use display and analysis instrument, including the steps of connecting the power source and transmitter unit a sensor head; performing a test and measurement by positioning the sensor head to sense and measure the desired parameter; transmitting data to the display and analysis instrument; and receiving the transmitted data on the display and analysis instrument. The display and analysis instrument may be connected to a sensor head, and preferably may receive wired or wirelessly transmitted test and measurement data from any number of communicably connected sensor heads. Wirelessly transmitted data may be received by another external display device such as a smartphone or similar computing device.
