Read first: Safety Information
Understand and follow operating instructions carefully. Use the tracer only as specified in
this manual; otherwise, the protection provided by the tracer maybe impaired.
DANGER
Electric Shock Hazard
Contact with electricity can cause electric shock, serious injury or death. To avoid electric
shock, personal injury or death follow these instructions.
WARNING
To avoid electric shock, personal injury, or death, follow these instructions:
•
Do not use if tracer appears damaged. Visually inspect the tracer to ensure the cases
are not cracked and back case is securely in place.
•
Inspect and replace leads if insulation is damaged, metal is exposed, or probes are
cracked.
•
Never use on circuits or systems that have voltages in excess of 600V AC/DC.
•
Never use the tracer with a remote ground in patient care areas. Ground currents
generated by the tracer may create a shock hazard for electrically susceptible patients.
•
Always test the remote ground system to confirm that its resistance is less than 100
ohms from remote ground to circuit neutral.
•
Always check circuits to verify that the hot, neutral and ground are wired correctly.
•
Do not use tracer if it operates abnormally as protection maybe impaired.
•
Do not use during electrical storms or in wet weather.
•
Do not use around explosive gas, dust, or vapor.
•
Do not apply more than the rated voltage to the tracer.
•
Do not use without the batteries and the back case properly installed.
•
Remove the test leads from the circuit prior to removing the battery cap.
•
Do not attempt to repair this unit as it has no user-serviceable parts except a fuse.
CAUTION
To protect yourself, think "Safety First":
•
Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
•
Use appropriate personal protective equipment such as safety glasses, face shields,
insulating gloves, insulating boots, and/or insulating mats.
•
Never ground yourself when working on an electrical circuit.
•
Always make the ground or neutral connection first, and remove last when using clip
leads or adaptor cord.

Introduction
The SureTest
®
Circuit Tracers are powerful, versatile, easy-to-use troubleshooting test tools
for finding breakers and hidden wire problems in residential/commercial/industrial
environments. These tracers work on closed (energized) and open (de-energized) circuits.
They identify circuit breakers, find opens and shorts, and trace wires behind walls.
The tracers are available in three configurations. Each kit contains the same transmitter
(TR-958) and test lead kit (TL-956). The 954 kit has a Receiver (RC-954) with a 7-digit
LED screen and a Hard Case (C-954). The 956 has a Receiver (RC-958) with a rotating,
super-bright OLED display and an AC/DC power indicator, and a Hard Case (C-954). The
958 also has the high-end Receiver (RC-958), adds an Inductive Clamp (IC-958) with
Battery Pack (BP-958), and a larger Hard Case (C-958).
