This Operating Manual covers information on safety and

cautions. Please read the relevant information carefully

and observe all the Warnings and Notes strictly.

Warning

To avoid electric shock or personal injury, read the

"Safety Information" and "Rules for Safe Operation"

carefully before using the Meter.

Your Multimeter is an intelligent digital one, a precise

instrument with a resolution of 80,000 counts and up-to

-date automatic computer calibrating function. High

resolution A/D converter and micro-controller data

processing technique is adopted in the Meter, featured

with intelligence, high precision and multi-functions. The

Meter can be widely used in laboratory field service,

domestic and other applications. All the functions and

ranges have full overload protection.

In addition to the conventional measuring functions, it is

equipped with a RS232C standard serial port for easy

connection with computer to realize macro recording and

monitoring and capture of transient dynamic data,

displaying change of waveform during the measurement,

providing data and evidence to engineering technicians

for scientific research. This is also a highly applied digital

multimeter of good performance with display backlight.

Open the package case and take out the Meter. Check

the following items carefully to see any missing or

damaged part:

Safety Information

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

CAT IV: Primary supply level, overhead lines,

cablesystems etc.

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.

International electrical symbols used on the Meter and

in this Operating Manual are explained on page 8

Rules For Safe Operation(1)

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.

Never working at an effective voltage over 60V in

DC or 30V rms in AC for there is danger of electric

shock.

Use the proper terminals, function, and range for

your measurements.

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.

When using the test leads, keep your fingers behind

the finger guards.

Disconnect circuit power and discharge all high-

voltage capacitors before testing resistance,

continuity, diodes, current or capacitance.

Before measuring current, check the Meter's fuses

and turn off 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 RS232C interface cable

from the Meter and turn the Meter power off before

opening the Meter case.

When servicing the Meter, use only the same model

number or identical electrical specifications

replacement parts.

The internal circuit of the Meter shall not be altered

at will to avoid damage of the Meter and any accident.

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.

The Meter is suitable for indoor use.

Turn the Meter off when it is not in use and take

out the battery when not using for a long time.

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.
