Safety Infor m at ion: Read First

Warning

To avoid electrical shock or fire if a test tool input is connected t o m ore than 42 V peak (30 Vrms) or on circuits of more than 4800 VA:

• Use only insulated voltage pr obes and t est

leads (and adapters) supplied with t he t est tool, or equivalents as specified i n t he accessory list, see Chapter 8.

• Before use, inspect voltage pr obes, test

leads and accessories for mechanical damage and replace when damaged.

• Remove all probes, test l eads and

accessories that are not in use.

• Always connect the battery char ger f i r st t o

the ac outlet befor e connect ing it to the test tool.

• Do not connect the ground spring to

voltages higher than 42 V peak ( 30 Vrm s) from earth ground.

• Do not apply voltages that di f f er m or e t han

600 V from earth ground t o any input when measuring in a CAT III environment. Do not apply voltages that di f f e r m or e t han 1000 V from earth ground t o any input when measuring in a CAT II envi r onm ent .

• Do not apply voltages that di f f er m or e t han

600 V from each other t o t he i solated inputs when measuring in a CAT III environment. Do not apply voltages that di f f e r m or e t han 1000 V from each other t o t he i solated inputs when measuring in a CAT II environment.

• Do not apply input voltages above t he r at i ng

of the instrume nt . Use caut i on w hen using 1:1 test leads because the pr obe t i p voltage will be directly transmitted to the test tool.

• Do not use expos e d metal BNC or banana

plug connectors.

• Do not insert metal obj ects into connectors.

• Always use the test tool only in the manner

specified.

Voltage ratings that are mentioned in the warnings, are given as limits for “working voltage”. They repr esent V ac rms (50-60 Hz) for ac sinewave applications and as V dc for dc applications.

Overvoltage Category III refers to distribution level and fixed installation circuits inside a building. Overvoltage Category II r ef er s t o local level, which is applicable for appliances and portable equipment.

Users Manual

The terms ‘Isolated’ or ‘Electrically floating’ are used in this manual to indicate a measurement in which the t est tool input BNC or banana jack is connected to a voltage different fr om ear t h gr ound.

The isolated input connectors have no exposed metal and are fully insulated to protect against electr ical shock.

The red and gray BNC jacks, and the red and black 4-mm banana jacks can independently be connected to a voltage above earth ground for isolated ( elect r ically floating) measurement s and ar e r at ed up t o 1000 Vr m s CAT II and 600 Vrms CAT III above earth ground.

If Safety F eat ures are Impaired

Use of the test tool i n a m anner not speci f ied may impair the pr ot ect ion provided by the equipment .

Before use, inspect the test leads for m echanical damage and replace damaged test leads!

Whenever it is likely that safety has been impaired, t he test tool must be tur ned off and disconnected from t he line power. The matter should then be r ef er r ed to qualified personnel. Safety is likely to be impaired if, for example, the test t ool fails to per f or m the intended measurements or shows visible damage.
