English Introduction
The SDAR SMT-51C Analog Multimeter is a classic measurement tool featuring an easy-to-read analog dial with color-coded scales. This compact device (916031mm) utilizes a sensitive internal-magnet movement housed in a dual-molded casing, providing reliable performance for basic electrical testing. It measures DC voltage up to 30V with ±4% FS accuracy and includes continuity check function with audible buzzer alert. 46
Equipped with standard test leads, this battery-powered (1.5V AA) multimeter performs essential tasks like battery voltage checking and circuit testing without requiring external power. The anti-slip rubber casing and gold-plated test probes ensure durability, while the mechanical zero-adjustment screw maintains measurement consistency. Ideal for electronics education and field maintenance, its straightforward operation makes it accessible for both beginners and professionals. 2829
The product emphasizes user-friendly features including a lightweight design (approx. 83g), clear scale markings, and protective terminal insulation. As a traditional analog instrument, it effectively demonstrates parameter fluctuations during dynamic measurements, serving as a practical tool for understanding fundamental electrical principles in workshops and training environments. 1017
