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. Safety Information: Read First • 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. Measurement Category III refers to distribution level and fixed installation circuits inside a building. Measurement Category II refers to local level, which is applicable for appliances and portable equipment. 5

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.

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.
