Safety Information
Go to www.fluke.com to register your product and find more
information.
A Warning identifies conditions and procedures that are dangerous to
the user.
Warning
To prevent possible electrical shock, fire, or personal injury:
•Read “Safety Information” before using the meter.
•Do not use the meter if it is damaged. Before using the
meter, inspect the case. Look for cracks or missing
plastic. Pay particular attention to the insulation
surrounding the connectors.
•Make sure the battery door is closed and latched
before operating the meter.
•Remove test leads from the meter before opening the
battery door.
•Inspect the test leads for damaged insulation or
exposed metal. Check test lead continuity. Replace
damaged test leads before using the meter.
•Do not use the meter if it operates abnormally.
Protection may be impaired. When in doubt, have the
meter serviced.
•Do not operate the meter around explosive gas, vapor,
or dust.
•Do not use in a damp or wet environment.
•Use only type AA batteries, properly installed in the
meter case, to power the meter.
•When servicing the meter, use only specified
replacement parts.
•Use caution when working above 30 V ac rms, 42 V ac
pk, or 60 V dc. Such voltages pose a shock hazard.
•When using the probes, keep fingers behind the finger
guards on the probes.
•Connect the common test lead before connecting the
live test lead. When disconnecting test leads,
disconnect the live test lead first.
•Do not use AutoHold to determine if dangerous voltage
is present. AutoHold 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 opening 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.
•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.
