Warning

To avoid electrical shock or fire:

• Use only the Fluke power supply, Model

BC190 (Battery Charger / Power Adapter).

• Before use check that the selected/indicated

range on the BC190 matches the local line power voltage and frequency.

• For the BC190/808 universal Battery Charger /

Power Adapter) only use line cords that comply with the local safety regulations.

Note:

To accomodate connection to various line power sockets, the BC190/808 universal Battery Charger / Power Adapter is equipped with a male plug that must be connected to a line cord appropriate for local use. Since the adapter is isolated, the line cord does not need to be equipped with a terminal for connection to protective ground. Since line cords with a protective grounding terminal are more commonly available you might consider using these anyhow.

Safety Information: Read First

Warning

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

• Use only insulated voltage probes, test leads

and adapters supplied with the test tool, or indicated by Fluke as suitable for the Fluke190 ScopeMeter series.

• Before use, inspect voltage probes, test leads

and accessories for mechanical damage and replace when damaged.

• Remove all probes, test leads and accessories

that are not in use.

• Always connect the battery charger first to the

ac outlet before connecting it to the test tool.

• Do not connect the ground spring (figure 1,

item f) to voltages higher than 42 V peak (30 Vrms) from earth ground.

• Do not apply voltages that differ more than 600

V from earth ground to any input when measuring in a CAT III environment. Do not apply voltages that differ more than 1000 V from earth ground to any input when measuring in a CAT II environment.

• Do not apply voltages that differ more than 600

V from each other to the isolated inputs when measuring in a CAT III environment. Do not apply voltages that differ more than 1000 V from each other to the isolated inputs when measuring in a CAT II environment.

• Do not apply input voltages above the rating of

the instrument. Use caution when using 1:1 test leads because the probe tip voltage will be directly transmitted to the test tool.

• Do not use exposed metal BNC or banana plug

connectors.

• Do not insert metal objects 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 represent 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 refers to local level, which is applicable for appliances and portable equipment.

Fluke 196C/199C

Users Manual

The terms ‘Isolated’ or ‘Electrically floating’ are used in this manual to indicate a measurement in which the test tool input BNC or banana jack is connected to a voltage different from earth ground.

The isolated input connectors have no exposed metal and are fully insulated to protect against electrical 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 (electrically floating) measurements and are rated up to 1000 Vrms CAT II and 600 Vrms CAT III above earth ground.

If Safety Features are Impaired

Use of the test tool in a manner not specified may impair the protection provided by the equipment.

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

Whenever it is likely that safety has been impaired, the test tool must be turned off and disconnected from the line power. The matter should then be referred to qualified personnel. Safety is likely to be impaired if, for example, the test tool fails to perform the intended measurements or shows visible damage.
