 Before you use the meter, inspect the case. Pay particular

attention to the insulation surrounding the connectors.

Inspect the test leads for damaged insulation or exposed

metal. Check the test leads for continuity. Replace

damaged test lead before you use the meter.

 Do not use the meter if it operates abnormally. Protection

may be impaired. When in doubt, have the meter

serviced.

 Do not operate the meter in a place where flammable or

explosive gas (or dust) is present.

 Do not apply more than the rated voltage, as marked on

the meter, between terminals or between any terminal

and earth ground.

 When measuring current, turn off circuit power before

connecting the meter in the circuit. Remember to place

the meter in series with the circuit.

 Use caution when working above 30V AC rms, 42V peak,

or 60V DC. Such voltages pose a shock hazard.

 When using the probes, keep your fingers behind the

finger guards on the probes.

 When making connections, connect the common test

lead before you connect the live test lead.

 When you disconnect test leads, disconnect the live test

lead first.

 Remove all test leads from the meter before you open

the battery cover or portion of the case.

 Do not operate the multimeter with the battery door or

portions of the case loosened or removed.The battery

door should be securely closed before operating the

multimeter.

 To avoid false readings, which could lead to possible

electric shock or personal injury, replace or charge the

battery as soon as the low battery indicator (

)

appears.

 Use the meter only as specified in this manual; otherwise

the safety features of the meter may be impaired.

 When in Relative mode or in Data Hold mode, caution

must be used because hazardous voltage may be

present.

 Do not electrically connect yourself to ground. Use

extreme caution because you may ground yourself if you

are careless.

 Do not operate this meter if your hand or the meter is

wet.

 Adhere to local and national safety codes.

 Use Individual protective equipment to prevent shock and

arc blast injury when working in an area where hazardous

live conductors are exposed.

 Remaining endangerment: When an input terminal is

connected to dangerous live potential, it is to be noted

that this potential at all other terminals can occur!

 CATIII - Measurement category III is for measurements

performed in the building installation. Examples are

measurements on distribution boards, circuit breakers,

wiring, including cables, bus-bars, junction boxes,

switches, socket-outlets in the fixed installation, and

equipment for industrial use and some other equipment, for

example, stationary motors with permanent connection to

fixed installation. Do not use the meter for measurements

within Measurement Categories IV.

 Use the proper terminals, function and range for your

measurements.

 Before measuring current, check the meter’s fuses and

turn off power to the circuit before connecting the meter

to the circuit.

 Before rotating the mode selection dial to change

functions, disconnect test leads from the circuit under

test.

 Be sure the test leads and switch are in the correct

position for the desired measurement.

 Never measure resistance in a circuit when power is

applied.

SPECIFIC SAFETY RULES

Battery products do not have to be plugged into

an electrical outlet; therefore, they are always in

operating condition. Be aware of possible hazards

when not using your battery product or when changing

accessories. Following this rule will reduce the risk of

electric shock, fire, or serious personal injury.

Do not place battery products or their batteries near

fire or heat. This will reduce the risk of explosion and

possibly injury.

 Do not crush, drop or damage battery pack. Do not

use a battery pack or charger that has been dropped

or received a sharp blow. A damaged battery is subject

to explosion. Properly dispose of a dropped or damaged

battery immediately.

Batteries can explode in the presence of a source

of ignition, such as a pilot light. To reduce the risk of

serious personal injury, never use any cordless product

in the presence of open flame. An exploded battery can

propel debris and chemicals. If exposed, flush with water

immediately.

For best results, your battery product should be

charged in a location where the temperature is more

than 50°F but less than 94°F. To reduce the risk of serious

personal injury, do not store outside or in vehicles.
