Page 3: Safety Rules
1. Safety Rules CAUTION RISK OF ELECTRIC SHOCK This tester has been designed with your safety in mind. However, no design can completely protect against incorrect use. Electrical circuits can be dangerous and/or lethal when lack of caution or poor safety practices are used. -
Page 4: Safety Checks
When using the tester with test leads, ensure that they are safe and properly authorized Disconnect the tester from any external circuit when checking or changing the Fuse and/or batteries. CAUTION READ THE MANUAL Follow the instructions in the Manual for every measurement. -
Page 5: General Description
DON'T TOUCH Don't touch exposed wiring, connections or other "Live" parts of an electrical circuit. If in doubt, check Do not use cracked of broken test leads. THIS INSTRUMENT SHOULD ONLY BE USED BY A COMPETENT, SUITABLY TRAINED PERSON. REMEMBER SAFETY IS NO ACCIDENT CAUTION RISK OF ELECTRIC SHOCK CAUTION READ THE MANUAL... -
Page 6: Product Description - Transmitter
The Transmitter (Tx), draws a current from the mains supply circuit to which it is connected to. The Signal Current from the Tx is at about 10kHz. The Transmitter is powered by the mains and requires no batteries. The 10kHz signal current generated by the Tx is then searched (sniffed) by the Receiver to detect the Fuse, Circuit Breaker or the faulty circuit. - Page 7 Plug Plug Shown can be different from country to country. The 10KHz generated signal current can be detected using the Sniffer (Receiver). Once the mains voltage is connected to the Transmitter, a Red Led will lit, indicating that Power has been connected to the Tx. Once the Red Led Lit, the Tx should generate The 10Khz signal current into wire or the circuit to trace.

Page 8: Product Description - Receiver
5. Product Description - Receiver The Receiver is using its tip to sense the 10KHz signal which has been generated by the Transmitter. In the tip, there is an inductor Sensor Tip which is part of the tuned circuit. We call it the Sensor Signal tip. -

displayed on the bar- graph. This is proportional to the signal strength being sniffed by the receiver. The strength of the signal is showed on a LED bar- graph. The more LEDs ON, the stronger the signal Strength. The strength of the signal can also be eard from the buzzer. - Page 10 AUTO-OFF The sniffer has an Enser-Save auto-off timer which run from the time the sniffer has been turned ON. After auto-off, the user will need to switch the Sniffer ON again, if he wants to use it. The auto-off can not be over-riden by the signal strength.

BUZZER The buzzer has a High Pitch sound and sounds during start up (Turn-on test procedure) to indicates it's working properly, then it beep faster and faster when the signal strength is stronger. The stronger the signal strength, the faster it beeps. A weak signal make the buzzer sounds slow. -
Page 12: Operating Instructions
Power On - Led Indication When the Transmitter is connected to the power source, the Led will LIT. This indicates power is present on the transmitter and current signal is being transmitted in the wires. 8. Operating Instructions (1) Connect the Transmitter to the socket (power (CBTF). - Page 13 (2) Go to the board where the circuit breakers are located. (3) Start the Sniffer (see starting the sniffer). The Bar-Graph circuit breaker has no signal on it. It buzz very slow too. The battery voltage is ok. You can go left and right and change row as you want to.
-
Page 14: Starting The Receiver
The Bar-Graph shows that the last circuit has the signal on it. It buzz faster too. The battery voltage is ok. TO START THE SNIFFER, PRESS THE ON BUTTON 9. Starting the Receiver To start the receiver, depress the ON button. The Bar-Graph will lit to show it is in working order. -
Page 15: Finding Earth Fault
MAKE SURE ALL THE CIRCUIT BREAKERS ARE ON Now, for example, start scanning from the top left row, then go down etc..., But you can scan the breakers in any order. While you are scanning, observe the bar- graph and listen to the buzzer. The Circuit breaker which supply the Transmitter circuitry is the one, which, when pointed out by the tip, has the most LEDs lit on the bar-graph and the fastest buzz. -
Page 16: Notes
For example, say, you have a short between Line and Earth, but you don't know where the short is. Connect the Transmitter, using an adaptor, in serie, in the line. If the Protection device trips, then you will have to bypass the protection device for the duration of this test. -
Page 17: Very Important Features
13. Very important features Finding Neon Lightning Circuits without the transmitter. are connected to Neons Light circuitry. This is usefull to check quickly which circuit breaker is will induce a signal which can be detected by the sniffer. EnerSave The Sniffer is software driven and has an Auto-off feature which turn the receiver off automatically after a certain time. -
Page 18: Principle Of How It Work Display Results
14. Principle of How it work Display Results TRANSMITTER - Tx Internally, the transmitter has a fuse in line with the line(hot) wire. The voltage present on these terminals ( input wires) from that voltage. That internal power supply, supply all the internal circuitry. - Page 19 RECEIVER - Rx The Receiver, or sniffer is a tuned receiver. The tuned circuit comprises of a capacitor and an inductor (LC tank circuit). The inductor is situated in the tip of the sniffer. signal. The microprocessor reads that smoothed signal which is proportional to the detected signal and display it on a bar-graph.

Page 21: Replacing The Battery
Check for cracks in any wires and sign of damages. Verify that there are no cracks or damages on the transmitter lead connection or on any of the optional accessories. Make sure the housing of the transmitter and receiver are not damaged. If there is any doubt, consult your nearest service center. -
