General
The instrument is a high performance, high accuracy, 3 ¾ digit multi-meter, it uses the LCD with 33
mm high figure to make the Reading clear, the display simple and the operation convenient.
The instrument can measure DC and AC voltage, DC and AC current, Resistance, Capacitance,
Frequency, Duty Circle, Diode and Continuity test; and it also has the features of Bar Graph, Unit
Indication, Data Hold, Relative Value Measurement (REL), USB Interface, AUTO/MANUAL range
selection, Auto Power Off and Alarm Buzzer. The instrument adopts the directly driven
4 digits microprocessor and dual-integral A/D converter, which provide the high solution and high
accuracy digital displaying driver. Because of its outstanding features, it is an excellent tool and
most suitable for lab. Factory, maintenance and repair users.

Safety Note
The instrument meets the standard of IEC1010 ( safety standard promulgated by the International
Electrician Committee). Design and manufacture complied with the standard of Pollution Degree 2.
WARNING:
To avoid endangering the safety of the users, should read the operation manual carefully before
operation, and strictly aide by the safety warning information and operation description to use the
instrument.
1.
Caution to avoid the electric shock when measuring the voltage higher than 30V, the current
higher than 10mA, AC Power Lines with Inductive Load and the AC Power Lines during the period of
Electric Power Fluctuation.
2.
Before measuring, should check if the function knob is set in the correct range, make sure the
test lead connects reliably, links up correctly, and insulates properly to avoid the electric shock.
3.
It means the requirements of the safety standard only to use the instrument with the equipped
test lead. If the test lead is broken, should replace it by the same type and same electric
specification test lead.
4.
Do not replace the inside fuse by the unconfirmed one. Only replace it by the same type and
specification fuse. Before replacement, should keep the test lead off the tested point to make sure
there is no any signal at the input terminal.
5.
Do not replace the inside battery by the unconfirmed one. Only replace it by the same type and
electric specification battery. Before replacement, should keep the test lead off the tested point to
make sure there is no any signal at the input terminal.
6.
When measuring electricity, do not connect the body with the ground directly, and do not touch
the possible exposed metal terminal, output socked or lead clamp with ground potential. Usually
use the dry cloth, rubber overshoes, rubber cushion and other insulated materials to keep the body
isolated with the ground
7.
Do not store and use the instrument in high humility, high temperature, combustible, explosive
and strong magnetic places.
