This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category
(CAT. II 1000V, CAT. III 600V) and double insulation.
CAT. II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient voltage
overvoltages than CAT. III
CAT. III: Distribution level, fixed installation, with smaller transient overvoltages than CAT. IV
Use the Meter only as specified in this operating manual,
otherwise the protection provided by the Meter may be impaired.
In this manual, a Warning identifies conditions and actions that pose hazards to the user, or may
damage the Meter or the equipment under test.
A Note identifies the information that user should pay attention on.

Warning
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter
or to the equipment under test, adhere to the following rules:
• Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case
(or part of the case) is removed. Look for cracks or missing plastic. Pay attention to the insulation
around the connectors.
• Inspect the test leads for damaged insulation or exposed metal. Check the test leads for
continuity. Replace damaged test leads with identical model
number or electrical specifications before using the Meter.
• Do not apply more than the rated voltage, as marked on the Meter, between the terminals or
between any terminal and grounding.
• The rotary switch should be placed in the right position and no any changeover of range shall
be made during measurement is conducted to prevent damage of the Meter.
• When the Meter working at an effective voltage over 60V in DC or 30V rms in AC, special
care should be taken for there is danger of electric shock.
• Use the proper terminals, function, and range for your measurements.
• If the value to be measured is unknown, use the maximum measurement position.
