Điểm nổi bật
This Multi-meter is an accurate, safe, battery operated, rear tilt-standby, easy to operate handheld instrument with robust protective holster alongside and the adjustable back tilt device with hook-up design. It can offer accurate, reliable measurements of DC/AC Voltage, DC Current, Resistance and DioDE, LED, Transistor, Decibels, Continuity and Capacitance with very high sensitive quality movement, and 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.
