This meter is a steady performance, battery-driven 3 1/2 digital LCR meter, which
has the figure of unit symbol displaying, accuracy reading and wide range
measurement. This meter has the function of measuring inductance, resistance,
capacitance test. In addition, it’s ideal for testing SMD type components. Plus,
the meter offers advanced features, such as the ability to perform precision
measurements. It is an ideal hand-held tool for labs, factories and
radio-technology.
Please read this operation manual carefully before your operation!

Matters need attention before measurement

Matters need attention before measurement
When signal displays at the state of power on, should replace the battery
to ensure the accuracy;
Do not switch the function knob when measuring.
Capacitance measurement function is used to measure the capacitance value,
can’t used to measure the figure of merit of reactive power. It perhaps gets
a wrong reading if measure the capacitance value of resistance; before measuring,
it should release the capacitor completely. Beware of polarity when connects
the polar capacitor. Do not connect the test COM with voltage source; otherwise
it will cause grievous damage. Do not connect the test leads short-circuit,
