  • Page 3: Safety Rules

    BESANTEK 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

    BESANTEK Avoid bare hand to hand contact between the tester and extended test leads. 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.
  • Page 5: General Description

    BESANTEK DON'T TOUCH Don't touch exposed wiring, connections or other "Live" parts of an electrical circuit. If in doubt, check the circuit first for voltage before touching it. Do not use cracked of broken test leads. THIS INSTRUMENT SHOULD ONLY BE USED BY A COMPETENT, SUITABLY TRAINED PERSON.
  • 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 BESANTEK Plug Plug Shown can be different from country to country. a current at an approximative frequency of 1 0kHz. 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.
  • Page 8: Product Description - Receiver

    BESANTEK 5. Product Description - Receiver The Receiver is using its tip to sense the 1 0kHz signal which has been generated by the Transmitter. In the tip, there is an inductor which is part of the tuned Sensor Tip/ circuit.
  • Page 9: Features - Receiver

    The output of the amplification is then measured and 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.
  • 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

    BESANTEK 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 source), supplied by the circuit breaker to find (CBTF) .
  • Page 13 BESANTEK (2) Go to the board where the circuit breakers are located. (3) Start the Sniffer (see starting the sniffer). The Bar-Graph shows that the first circuit breaker of the first row has no signal on it. It buzz very slow too.
  • Page 14: Starting The Receiver

    BESANTEK The Bar-Graph shows that the last circuit breaker of the first row has the signal on it. It buzz faster too. The battery voltage is ok. � TO START � •- THE SNIFFER. '" � � :JJ� � :;�...

  • 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. The Sniffer is capable to find circuits breakers which are connected to Neons Light circuitry. This is usefull to check quickly which circuit breaker is connected to a neon circuit. Most neons firing current will induce a signal which can be detected by the sniffer.
  • Page 18: Principle Of How It Work Display Results

    BESANTEK Sensor= TIP�! 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) is rectified and an internal power supply is created from that voltage.
  • Page 19 BESANTEK 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. The signal received on the tuned circuit is amplified, then rectified and smoothed to transfer it to a DC level signal.
  • Page 20: Display Bar-Graph

    BESANTEK 15. Display Bar-Graph The bar-graph is made out of Leds to Show the signal strength. 16. Automatic Battery test On the receiver, while it's testing the battery is constantly monitored the status of the battery is shown on the Battery O K And Tester On indicator Led.
  • 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.
