Abstract: A handheld multimeter includes an outer shell, a computer processor housed within the outer shell for processing data, and a pressure-sensitive display screen. The display screen is electrically coupled to the processor to enable the processor to display simulated input elements on the screen and enable the user to input data commands into the processor by contacting the display screen. A data port is coupled to the processor. A conductive probe assembly is structured to generate electrical data. The probe assembly is electrically coupled to the data port to enable communication of the electrical data between the probe assembly and the processor. The processor is configured to process the electrical data received from the probe assembly and display an output value on the display screen that includes at least one of an electrical voltage value, an electrical resistance value, and an electrical current value.
