SAFETY INFORMATION
This meter is designed and manufactured according to the safety
requirements set out by the IEC61010-1 standards for electronic test
instruments and the hand-hold digital multimeters. Its design and
manufacture is strictly based on the provisions in the CAT III 600V of
IEC61010-1 and the Stipulation of 2-Pollution Grade.
Safety Symbols
Risk of danger. Important information. See manual.

Earth ground
• To avoid possible electric shock, personal injury, or death, read
the following before using the Meter:
• Use the test leads supplied to ensure operation safety. If required,
they must be replaced with test leads of the same model or class.
• Inspect the test leads before use. Do not use them if insulation is dam
aged or metal is exposed. Check the test leads for continuity. Replace
damaged test leads before using. Do not use the Meter if it appears
damaged.
• Do not touch the metal tips of the test leads when the meter is con
nected to the circuit to be measured.

!WARNING

• When Voltage > 60 V dc or ac peak .keep your ngers behind the
nger guards.
• Verify the Meter’s operation by measuring a known voltage before and
after using it. Do not use the Meter if it operates abnormally.
Select the highest range if the value scale to be measured in the
manual range is unknown.
• Do not take voltage measurement if the value between the terminals
and earth ground exceeds 600V.
• Disconnect the test leads from the circuit under test before turning the
rotary selector to change functions.
• Disconnect circuit power and discharge all high voltage capacitors
before testing resistance, continuity, diodes, or capacitor.
• Do not store or use the meter in areas exposed to direct sunlight, at
high temperature or with high relative humidity.
• Do not touch live circuit or exposed metal
MAINTENANCE
• Before opening the rear of the meter, disconnect test leads from all
sources of electric current.
• Use damp cloth and mild detergent to clean the meter; do not use
abrasives or solvents.
• Whenever it is likely that safety protection has been impaired, make the
Meter
• Inoperative and secure it against any unintended operation.
• Have the Meter serviced only by qualied service personnel

To avoid possible electric shock, disconnect the test leads
from the circuit under test before replacing the battery. Replace
with the same type of battery.
Make sure the transformer jaw and the test leads are disconnected from
the circuit being tested before opening the case bottom. Check battery
has been installed and battery cover has been screwed before use. Re-
place the battery as soon as the battery indicator “ ” appears.
Performs replace battery
1. Disconnect test leads from live circuit, switch rotary switch to “OFF”
position.
2. Remove test leads form input terminals
3. Remove the screw from the battery cover, and separate the
battery compartment from the case bottom. Replace the battery with
3pcs of new 1.5V (AAA) batteries.
