Safety Information

• Before a current measurement, do the
fuse test.
• Use the correct terminals, function, and
range for measurements.
• Do not work alone.
• For current measurements, connect the
Meter to the circuit after you remove
circuit power. Always put the Meter in
series with the circuit.
• Comply with local and national safety
requirements when in hazardous
locations.
• Only use test leads that have the same
voltage, category, and amperage ratings
as the Meter and that are approved by a
safety agency. When used with optional
accessories, the lowest category rating
applies.
• Do not use TouchHold to determine if
dangerous voltage is present. TouchHold
will not capture unstable or noisy
readings.
• To avoid false readings, which could lead
to possible electric shock or personal
injury, replace the battery as soon as the
battery indicator () appears.
• Remove test leads from the Meter before
you open the battery door.
• Close and latch the battery door before
using the Meter.
• To avoid personal injury or damage to the
Meter, use only the specified replacement
fuse, 440 mA 1000 V fast-blow, Fluke PN
943121.
• Do not exceed the Measurement Category
(CAT) rating of the lowest rated individual
component of a Product, probe, or
accessory.
• Do not use the TL175 or TP175 test
probes in CAT III or CAT IV environments
without the probe tip fully extended and
correct category rating visible in the
window.
• When the TL175 is used with instruments
or other accessories, the lowest category
rating of the combination applies. One
exception is when the probe is used with
the AC172 or AC175.
