CAT. III: Distribution level, xed installation, with smaller transient overvoltages than CAT. IV
Use the Meter only as specied in this operating manual, otherwise the protection provided
by the Meter may be impaired.
In this manual, a Warning identies conditions and actions that pose hazards to the user, or
may damage the Meter or the equipment under test.
A Note identies the information that user should pay attention to.
International electrical symbols used on the Meter and in this Operating Manual are
explained on page 4.
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:
• 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 specications
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 eective 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 and
reduce the range stop by step until a satisfactory reading is obtained.
• Do not use or store the Meter in an environment of high temperature, humidity, explosive,
inammable and strong magnetic eld. The performance of the Meter may deteriorate after
dampened.
• When using the test leads, keep your ngers behind the nger guards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, capacitance or current.
• Before measuring current, check the Meter’s fuses and turn o power to the circuit before
connecting the Meter to the circuit.
• 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.
• Remove test leads and multi-purpose socket from the Meter and turn the Meter power o
before opening the Meter case.
• When servicing the Meter, use only the same model number or identical electrical
specications replacement parts.
• The internal circuit of the Meter shall not be altered at will to avoid damage of the Meter
and any accident.
