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
Warning
To avoid endangering the users safety, should read the operation
manual carefully before operation, and strictly obey the safety
warning information and operation description when 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.
