Fluke 196C user manual Safety Information Read First, Do not insert metal objects into connectors

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.
