GENERAL SPECIFICATIONS
The Klein Tools ET450 Advanced Circuit Tracer kit is a professional tracer for
energized and de-energized breakers, fuses, and wires. When the Transmitter
is connected to a circuit, the Receiver's sensitivity can easily be adjusted to
detect the transmitted signal on breakers, fuses, and wire through drywall,
cement block, and underground.

WARNINGS - GENERAL
To ensure safe operation and service of the meter, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
• Risk of electric shock and burn. Contact with live circuits could result in death or
serious injury.
• NEVER use the tester on a circuit with voltages that exceed the category-based
rating of this tester.
• Inspect the meter and test leads before use. DO NOT use if they appear
damaged or malfunctioning in any way
• Ensure leads are fully seated, and use caution when connecting to live circuits
• DO NOT use testers during electrical storms or in wet weather.
• Turn off testers and disconnect test leads before attempting to replace batteries.
• Turn off testers and disconnect test leads before attempting to replace the fuse.
• To avoid electrical shock, do not operate the tester while battery door is
removed.
• DO NOT open the case, other than the battery compartment.
• Use caution when working with voltages above 25V AC RMS, or 60V DC. Such
voltages pose a shock hazard.
• ALWAYS adhere to local and national safety codes. Use personal protective
equipment to prevent shock and arc blast injury where hazardous live
connectors are exposed.
