A Digital Multi-function Meter is an advanced instrumentation device capable of measuring and displaying multiple electrical parameters through a single unit. Its operation is based on programmable signal conditioning and high-precision analog-to-digital conversion. The core system routes input signals (voltage, current, temperature, etc.) through configurable conditioning circuits, which are then processed by a high-resolution ADC. A built-in microprocessor performs real-time calculations for parameters like True-RMS, power, frequency, and energy, while supporting automatic range switching and sensor linearization.
