INTRODUCTION
This Multi-meter is an accurate, safe, battery operated, rear
tilt-stand, 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 measurement
of DC/AC Voltage, DC Current, Resistance and Diode, LED,
Transistor, Decibels, and Capacitance with very high sensitive
quality movement, and good-designed circuit, as well as mirrored
Aluminum dial plate etc. It has the perfect full overload &
miss-used protection via Fuses, Oxide Varactor & Diodes. It is an
ideal instrument for indoor use in the laboratory, school, workshop,
hobby and home applications.
