TROUBLESHOOTING & CONSTRUCTION TIPS

SITUATION

LIKELY CAUSE

SOLUTION

No indication:  

no green LED  

and buzzer.

The breaker for that circuit is 

not in the box being scanned.

Find and scan the box that supplies that circuit.

The breaker is off.

Look for the breaker that is off and turn it on.

Multiple indications 

on second scan.

First scan was performed  

too quickly.

Scan again, moving the Receiver slowly.  

Keep the nose of the Receiver close to  

the breaker, and maintain proper orientation.

Receiver indicates 

breaker above the 

correct one. 

Receiver is held at an incorrect 

angle, with only the tip of the 

Receiver contacting the breaker. 

Hold the Receiver at an angle so the entire 

Contact Area of the Receiver touches each 

circuit breaker as shown in Figures B, C, and D.

Receiver does  

not operate.

Low battery.

Install new 9V alkaline battery with an 

extended expiration date at least 3 years 

beyond the current date.

BEFORE YOU BEGIN

ZIRCON

®

 CIRCUIT BREAKER FINDERS WORK BY SENSING AN ELECTRONIC SIGNAL FROM  

THE TRANSMITTER.
- Always use a new 9V alkaline battery with an extended expiration date at least 3 years beyond  

the current date. Match battery direction to image inside of battery cavity.
- Readings should always be consistent and repeatable.
- Zircon circuit breaker finders should be used in a dry environment.
- Compatible with aluminum and copper circuit wiring.
- Clean transmitter with dry cloth only. Do not expose product to liquids. 
- If the device is used in a manner not specified here, then the protection provided by the device  

may be impaired. 
- 80–300 V AC, 50–60 Hz, 4 W maximum.
- Maximum altitude: 2,188 yd (2,000 m).
- Maximum operating temperature: 104°F (40°C).
- Pollution Degree 2 or less.
- Maximum humidity: 80%.
- No part of this device may be replaced or repaired by anyone except the manufacturer. 
- Device must be used on a live circuit.

3. 

Slide the cover back 

on the Receiver until it 

snaps in place.

LOCATE A CIRCUIT

In a three-phase application, the Transmitter 

may be connected between any power line 

and neutral, or from line to line not to exceed 

300 V AC, in both wye and delta type power 

configurations. 

1. 

Attach the appropriate Accessory(ies) to the 

Transmitter. (

Figure A

)

2. 

Connect the Transmitter to the circuit to be 

identified. The Red LED will blink approximately 

five seconds then glow solid to indicate the 

Transmitter is functioning and the circuit is live.

3. 

At the circuit panel, turn the Receiver to ON. 

4. 

Holding the Receiver at an angle that gives 

maximum contact between the Contact Area and 
the breaker, slowly scan all breakers. (

Figure B

)

The Contact Area must touch each breaker 

during the scan. 
The first scan calibrates the tool. During first 

scan, the Receiver may indicate more than one 

breaker. This is normal. If there is more than one 

panel, perform this step on each panel without 

turning the Receiver off. 

5. 

Perform a second pass over the breakers to 

identify the breaker that corresponds with the 

outlet where the Transmitter is plugged in. 

When the green LED glows and the buzzer 

sounds, the Receiver is directly over the breaker 

for the outlet where Transmitter is plugged in.

Note:  

Some circuit 

boxes are 

mounted 

with breakers 

oriented 

vertically.  

See Figures 

C and D for 

proper Receiver 

orientation for 

horizontally 

or vertically 

oriented 
breakers.

Contact 

Area

6. 

Once the correct breaker is identified, turn it 

off and label the breaker for future reference.

7. 

With the Transmitter still plugged in,  

verify that the Red LED on the Transmitter is off, 

indicating a dead circuit, before beginning work.

TRACE THE CIRCUIT FOR  

A LIGHT FIXTURE

Screw the Light Socket Adapter into  

the socket where a bulb would  

normally go, then plug the Transmitter 

into the Adapter. 

STORE THE TOOL

Before storing, use a dry cloth to clean the parts. 

Do not expose the tool to liquids. 

Accessories

Alligator Clips  

(connect to bare or 

exposed wire)

120 V AC Plug

Light Socket 

Adapter

Blades (use with angled 

plugs such as 220V outlets)

Not Shown: Carrying/Storage Case

CAUTION: In no event may the Breaker ID 

Pro Transmitter be used where the voltage 

across the Transmitter exceeds 300 V AC, 

as this will cause failure of the device 

with consequent damage beyond repair.

INSTALL BATTERY

1. 

Remove the Receiver 

battery cover by lifting (a) 

and sliding (b) as shown. 
NOTE: If the clip is too 

tight to move easily,  

use a flat-head 

screwdriver to gently  

pry open.

2. 

Slide a new 9V alkaline battery into  

the compartment, terminals first, matching 

+

 

and 

 on the battery with markings in  

the compartment.
