## Description

A smart digital multimeter equipped with a high-contrast 9999-count VA colour LCD, designed for precise, everyday electronic measurements. Functioning as a quick-to-grab diagnostic tool for makers and engineers, it reliably measures AC/DC voltage, resistance, capacitance, and frequency while offering non-contact voltage (NCV) and live wire detection capabilities.

Traditional multimeters often require constant dial adjustments, which can slow down your workflow and risk blowing a fuse if the wrong range or mode is selected. The S1 solves this common pain point with an intelligent auto-measurement system that instantly identifies whether you are probing voltage, checking resistance, or testing continuity, streamlining both benchtop diagnostics and rapid field repairs.

Housed in a robust ABS plastic enclosure, this compact unit feels solid in the hand and features an internal 1000mAh lithium battery to completely eliminate the need for disposable 9V or AA cells.

### Key Features

- **Enjoy rapid, error-free diagnostics** with smart auto-measurement that instantly identifies AC/DC voltage, resistance, and continuity without requiring manual dial-switching.
- **Read measurements easily in any environment**—from dimly lit workshops to bright outdoor settings—thanks to the vibrant 9999-count dual-display VA colour screen and integrated flashlight.
- **Eliminate the hassle of swapping batteries** with the built-in 1000mAh rechargeable lithium battery, offering up to 5 hours of continuous runtime via a standard USB-C port.
- **Achieve highly accurate readings on complex AC signals** (such as PWM outputs or inverter drives) with True RMS measurement capabilities.
