Degree 2.
Warning
To avoid endangering the safety of the users, should
read the operation manual carefully before operation,
and strictly abide 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 meets 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 socket 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.
8. It is possible to damage the instrument and endanger
the safety of the users when measuring the voltage
over the range limit. The allowed maximum voltage
is printed on the front panel of the instrument, do not
input the range limit specified to avoid the electric
shock and instrument damage
9. Do not measure any voltage when connecting the test
lead with the current terminal to avoid damaging the
instrument and endangering the safety of the users.
10. Do not try to calibrate or repair the instrument,
should operate it by the specially trained or qualified
professional people.
11. The function/range selection knob should be set in
the correct range when measuring. When switching
the function/range selection knob, keep the test lead
off the tested object to make sure there is no any
signal at the input terminal. Do not switch the
function/range selection knob when measuring.
12. When LCD displays “ ”, please replace the

battery in time to make sure the measuring accuracy.
13. Do not allow to measure the voltage when
connecting the test lead with the current terminal!
14. Do not try to modify the inner circuit at will to avoid
damaging the instrument and endangering the safety
of the users.
