Safety Information

Before using, read all instructions. Only use the

multimeter as directed, or the multimeter may

be damaged, and you may be seriously injured.

• Limit operation to the specied measurement

category, voltage, or amperage ratings.

• Do not use the multimeter if it is damaged.

Before you use the multimeter, inspect the

case. Look for cracks or missing plastic.

Pay particular attention to the insulation

surrounding the connectors.

• Do not use the test leads provided for other

products. Use only the certied test leads

specied for this multimeter.

• Inspect the test leads for damaged

insulation or exposed metal.

• Before use, verify the multimeter’s operation

by measuring a known voltage.

• Only qualied technicians can perform

maintenance on this multimeter.

• Always use the specied battery type.

This multimeter is supplied with a battery

for power. Observe the correct polarity

markings before you insert the batteries to

ensure proper insertion of the batteries in

the multimeter.

• Check all Terminal Ratings. To avoid re or

shock hazard, check all ratings and markers

for this multimeter. Refer to this manual

for more information about ratings before

connecting anything to the multimeter.

READ AND SAVE THESE INSTRUCTIONS

Safety Information (cont.)

• Do not operate the multimeter with the

cover, or portions of the cover, removed or

loosened.

• Use Proper Fuses. Use only the specied

type and rating fuse for the multimeter.

• Do not operate if in any doubt about whether

the multimeter is safe to use. If you suspect

damage has occurred to the multimeter,

have it inspected by qualied service

personnel before further operation.

• To avoid electric shock, do not operate this

multimeter in wet or damp conditions.

• Do not operate in an area with explosive

substances or gasses.

• Always keep the multimeter’s surfaces clean

and dry.

• Do not apply more than the rated voltage (as

marked on the multimeter) between terminals,

or between terminal and earth ground.

• When measuring current, turn off the circuit

power before connecting the multimeter

in the circuit. Remember to place the

multimeter in series with the circuit.

• When servicing the multimeter, use only the

specied replacement parts.

• Use caution when working above 60V DC,

30V AC RMS, or 42.4V peak. Such voltages

pose a shock hazard.

• When using the test leads, keep your ngers

behind the nger guards on the test leads.

Never touch any exposed metal while

measuring.

• Remove the test leads from the multimeter

before you open the battery cover.

• To avoid false readings, which may lead to

possible electric shock or personal injury, replace

the battery as soon as the low battery indicator

appears and flashes.

Safety Information (cont.)

• Disconnect circuit power and discharge all high-

voltage capacitors before testing resistance,

continuity, diodes, or capacitance.

• Always use the proper terminals, function, and

range for your measurements. When the range

of the value to be measured is unknown, set

the rotary switch position as the highest range,

or choose the auto-ranging mode. To avoid

damages to the multimeter, do not exceed the

maximum limits of the input values shown in the

technical specication tables (see pages 31–34).

• Connect the common test lead before you

connect the live test lead. When you disconnect

the leads, disconnect the live test lead rst.

• Before changing functions, disconnect the test

leads from the circuit undergoing testing.

• Do not alter the internal circuitry of the

multimeter. This may result in serious injury.

• Do not use or store the multimeter in wet or

humid environments, in very high temperatures,

around explosive or flammable substances, or in

areas with strong magnetic elds. The multimeter

will not perform correctly, which may create a

safety hazard.

• Do not allow children to operate or play with

this multimeter.

Safety Information (cont.)

Measurement Category Safety Rating

Measurement Category (CAT)

Denitions:

The multimeter has a safety rating of 1000V,

CAT III and 600V, CAT IV.

Measurement CAT I applies to measurements

performed on circuits not directly connected

to the AC mains. Examples are measurements

on circuits not derived from the AC mains and

specially protected (internal) mains-derived

circuits, such as signal levels, electronics, and

limited-energy parts of equipment, which usually

have little chance of danger or overloading.

Measurement CAT II applies to measurements

performed on circuits directly connected

to the low-voltage installation. Examples

are measurements on energy-consuming

equipment such as TVs, PCs, portable tools,

and other household circuits.

Measurement CAT III applies to

measurements performed on equipment in

xed equipment installations, such as wiring,

distribution panels, feeders and short branch

circuits, and lighting systems in large buildings.

Measurement CAT IV applies to

measurements performed at the source of

the low-voltage installation. Examples are

electricity meters and measurements on

primary overcurrent protection devices and

ripple control units.
