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.
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.
Disconnect the power and discharge all high voltage capacitors
before testing resistance, diodes, or continuity.
Use the proper terminals, switch setting, and range for the
measurement or sourcing applications.
