Safety Information
This Meter complies with the standards IEC61010 safety measurement requirement: 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 overvoltages than
CAT. III
CAT. III: Distribution level, fixed installation, with smaller transient overvoltage 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 may 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 to.
International electrical symbols used on the Meter and in this Operating Manual are explained on page
XX.
Rules For Safe Operation
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:
z
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.
z
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.
z
Do not apply more than the 1000V rms between any terminal and grounding to avoid electric shock or
damages to the Meter.
z
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.
z
When the Meter working at an effective voltage over 60V in DC or 42V rms in AC, special care should
be taken for there is danger of electric shock.
z
Use the proper terminals, function, and range for your measurements.
z
Do not use or store the Meter in an environment of high temperature, humidity, explosive, inflammable
and strong magnetic field. The performance of the Meter may deteriorate after dampened.
z
When using the test leads, keep your fingers behind the finger guards.
z
Disconnect circuit power and discharge all high-voltage capacitors before testing resistance,
continuity, diodes.
z
Before measuring current, check the Meter’s fuses and turn off power to the circuit before connecting
the Meter to the circuit.
z
Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might
produce false readings that can lead to electric shock and personal injury.
z
When servicing the Meter, use only the same model number or identical electrical specifications
replacement parts.
z
The internal circuit of the Meter shall not be altered at will to avoid damage of the Meter and any
accident.
z
Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No
abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and
accident.
z
The Meter is suitable for indoor use.
z
Turn the Meter off when it is not in use and take out the battery when not using for a long time.
z
Constantly check the battery as it may leak when it has been using for some time, replace the battery
as soon as leaking appears. A leaking battery will damage the Meter.
