For safety, read the users manual carefully and keep it

with the meter together for further reference.

Precautions：

To avoid possible electrical shock or personal injury, please pay

extra attention on those symbols indicated on the manual and

corresponding illustration.

Warning：Improper or careless may result in

personal injury or even death.

Caution：Improper or careless may result in

damage to the meter or other

equipment

Dual Insulation

AC- Alternating Current

DC- Direct Current

Grounding –Earth Terminal

Fuse

Warning

⚫Set the function switch and function key at the

proper position and function before measuring.

⚫Remove test leads from the circuit being tested

before switching functions.

⚫Do not apply more than the rated range of function

specified.

⚫Check and make sure the meter or test leads are

intact before use. Do not use the meter or test

leads if they appear damaged.

⚫When using the test leads, always keep hands

behind the guard ring.

- 3 -

⚫When measuring resistance, first switch off the

power to the circuit under test, and verify that the

voltage is zero.

⚫Keep the meter dry. Do not use it with wet hands

or if there is moisture in or on the meter.

Warning

Maximum input voltage according to overvoltage

installation category of safety standard.

Caution

⚫Do not use the meter near equipment emitting noise

or in environments with sudden temperature

changes. Unstable or inaccurate reading may occur.

⚫When finished measurement, turn the function

switch back to OFF position to turn off the meter

completely. There is minor power exhaustion if the

meter is power off by auto-power-off function.

⚫If it is necessary to clean the meter, use a soft cloth.

Never use solvents.

⚫Do not expose the meter to direct sunlight, extreme

temperatures or moisture.

⚫Do not attempt to open the case except the battery

door for replacing battery or fuses.

⚫Any impact or drop of battery will result leakage

afterwards and possibly damage the meter. Thus,

don’t use those batteries if occurred.

⚫Take the battery out of the meter if it will not be used

for several weeks or storage.

⚫When symbol displays, replace the battery

immediately.
