The device functions by converting analog electrical signals into digital values through an analog-to-digital converter (ADC). This process allows the technician to read precise metrics—volts (V) for potential difference, ohms (Ω) for resistance, and amps (A) for current—on a digital screen, eliminating the parallax errors common with older analog "needle" gauges. Core Functionality and Application
