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, +/-DCV, DC Current, Resistance and Diode,
LED, Transistor, Decibels, Continuity test and Capacitance with
very high sensitive quality movement, double-sided glass-epoxy
PCB & good-designed circuit, as well as mirrored Aluminum dial
plate etc. It has the perfect full overload & mis-used protection via
two Fuses, Oxide Varactor & Diodes. It is an ideal instrument for
indoor use in the laboratory, school, workshop, hobby and home
applications.
