1. INTRODUCTION
This Multi-meter is an battery-powered, rear tilt-standby, easy-operated, heavy-safety handheld instrument with robust protective holster alongside and the adjustable back with hook-up design. It can offer accurate, reliable measurements of DC/AC Voltage, +/-Null DCV, DC Current, Resistance and DioDE, LED, Transistor, Decibels, Continuity test and Capacitance with very high sensitive quality movement, double-sides glass-epoy PCB & good – designed circuit, as well as mirrored AL dial plate esc. It has the perfect full overload & mis-used protection via two Fuses, Oxide Varactor & Diodes. It is an instrument for indoor use in the laboratory, school, workshop, hobby and home application.
