Introduction
The instrument of this series is a small hand-held 3 1/2 digital
multimeter featuring stable, highly reliable and anti-drop
performance. It is provided with a LCD display of 15 mm
height for clear reading. The circuit design takes LSI double
integral A/D converter as its core under the protection of an
overload protection circuit, making it a superior and handy
instrument. It can be used to measure DC and AC voltage, DC
current, resistance, diodes, transistors, temperature and for
in-circuit continuity test.
