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

Fluke 192/196/199

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.
