Safety Precautions and Procedures
This multimeter is designed according to relevant clauses of IEC1010. To avoid possible electrical
shock, fire, or personal injury, please read all safety information on this manual before you use the
product.
Do NOT exceed the "maximum value" indicated on the Panel.
Examine the connection of the test leads and the insulation of the product before
measuring a voltage higher than 36V DC or 25V AC.
Disconnect the test leads from the circuit before changing the mode.
Should check and confirm there is no damage in the instrument, the insulating barrier of
test lead is intact before using.
While holding the test leads, should pay special attention that your hands do not exceed
the plastic of the testing needle root, otherwise there is danger of getting electric shocks.
Before opening the back cover, must pull out the test leads. After closing the back cover
and screwing it back, it can carry on measuring. Be sure that it is done properly.
Before rotating the range selector to change functions, disconnect test leads from the
circuit under test.
Never input signal electronic voltage exceeding the limited value to avoid dangers and
damages.
The potential difference between the measurement public terminal COM and earth cannot
exceed 600V.
For the fuse, it must be replaced with an identical model if necessary. For the concrete
specification, please see the clause of maintenance or label on the instrument board.
If there is a symbol on the LCD display, it indicates low battery. Replace the battery to
ensure measurement accuracy.
