Warning
To avoid electrical shock or fire if a product
input is connected to more than 42 V peak
(30 Vrms) or 60 V dc:
• Use only insulated voltage probes, test leads
and adapters supplied with the product, or
indicated by Fluke as suitable for the Fluke
190-104 and 190-204 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 power adapter first to the
ac outlet before connecting it to the product.
• Do not touch voltages >30 V ac rms, 42 V ac
peak, or 60 V dc.
• Do not connect the ground spring (figure 1,
item d) to voltages higher than 42 V peak
(30 Vrms) from earth ground.
• Do not apply more than the rated voltage,
between the terminals or between each
terminal and earth ground.
• 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 product.
• Do not use exposed metal BNC connectors.
Fluke offers cables with plastic, safety
designed BNC connectors suitable for the
ScopeMeter product, see Chapter 7 ‘Optional
accessories’.
• Do not insert metal objects into connectors.
• Use the product only as specified, or the
protection supplied by the product can be
compromised.
• Carefully read all instructions.
• Do not use the product if it operates
incorrectly.
• Do not use and disable the product if it is
damaged.
• Keep fingers behind the finger guards on the
probes.
• Use only correct measurement category
(CAT), voltage, and amperage rated probes,
test leads, and adapters for the measurement.
