NOTICE! This notice indicates that a specific hazard or unsafe
practice will result in equipment or property damage, but
not personal injury.
This compact digital multimeter is used for measuring DC and AC
voltage, DC and AC current, resistance, diode, continuity, and logic level.
This meter was designed for the homeowner, hobbyist, and professional
needing to make electrical and electronic equipment measurements.
WARNING! Read and understand all instructions before using this
tool. Keep this manual for the safety warnings and precautions,
operating, inspection and maintenance instructions. When using
this tool, basic precautions should always be followed to reduce
the risk of personal injury and/or damage to the equipment. Note
that when this manual refers to a part number, it refers to the
parts list included. Before allowing someone else to use this tool,
make sure they are aware of all safety information.
1. Keep your work area clean and well lit. Cluttered and dark areas
invite accidents.
2. Operate in a safe work environment. Do not use machines or air
tools in damp or wet locations. Do not expose to rain.
3. Keep children, bystanders and visitors away from the work area. Do
not let them handle tools or extension cords. No one should be in
the work area if they are not wearing suitable protective equipment.
4. Store unused equipment. When not in use, tools must be stored in
a dry location to prevent rust. Always lock up tools and keep them
out of reach of children.
1. Dress properly, wear protective equipment.
2. Do not over reach; keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in
unexpected situations.

3. Stay alert, watch what you are doing and use your common sense.
Do not operate any machine or tool when you are tired, under the
influence of drugs, alcohol or medications.
This meter has been designed according to IEC-61010 concerning
electronic measuring instruments with a measurement category III (CAT
III 300V) and pollution degree 2. Measuring Category III (CAT III) is for
measurement performed on circuits directly connected to low voltage
installation (for example, measurements on household appliances,
portable tools, and similar equipment). Do not use this meter for
measurements within Measurement Category IV.
WARNING! To avoid possible electric shock or personal injury,
follow these guidelines:
1. Ensure that the batteries are correctly placed in the battery case
and connected properly.
2. Do not operate the meter with the battery cover or portions of the
case removed or loosened.
3. Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Inspect the test leads for damaged insulation or
exposed metal. Check test lead continuity. Damaged leads should
be replaced.
4. Do not use the meter if it operates abnormally. Protection may be
impaired. When in doubt, have the meter serviced an authorized
service center.
5. Do not operate the meter around explosive gas, vapor, or dust.
6. Do not apply a voltage or current higher that the selected range’s
upper limit between terminals.
7. Before use, verify the meter’s operation by measuring a known voltage.
8. When measuring current, turn off power to the circuit before
connecting the meter to the circuit. Remember to place the meter
in series with the circuit.
9. Use caution when working above 30V AC rms, 42V peak, or 60V
DC. Such voltages pose a shock hazard.

10. Do not touch any naked conductor with hand or skin and do not
ground yourself.
11. Connect the black test lead before connecting the red test lead. When
disconnecting test leads, always disconnect the red test lead first.
12. Remove the test leads from the meter before opening the battery
cover or the case.
13. Replace the battery as soon as the low battery indicator appears
on the LCD display.
CAUTION! To avoid possible damage to the meter or to the
equipment under test, follow these guidelines:
1. Disconnect circuit power and discharge all capacitors before
measuring resistance or continuity.
2. Select the proper function and range for your measurement.
3. Before measuring current, turn off the power to the circuit before
connecting the meter to the circuit.
4. Before rotating the range switch to change functions, disconnect
the test leads from the circuit under test.
5. Remove the test leads from the meter before opening the battery
cover or the case.
6. When finished measuring, switch off the power. Be sure to remove
the batteries when storing for long periods to avoid leakage
problems.
7. Do not use or store this instrument in a place of direct sunlight,
high temperature and high humidity.
1. Carefully remove the parts and accessories from the box.
2. Make sure that all items listed in the parts lists are included.
3. Inspect the parts carefully to make sure the tool was not damaged
while shipping.
4. Do not discard the packaging material until you have carefully
inspected and satisfactorily operated the tool.
