CL43 parts and functions

Operating CL43 Compact Locator

Using antennas
SA43 Rod antenna or SA05 Rod antenna is typically used by pointing it towards the approximate direction of a buried or hard-to-reach target cable, wire, or duct. A very narrow and accurate signal minimum, also called signal null, can often be detected exactly in the direction of the target accompanied by a maximum on both sides of this null. This is called the minimum locating method. Rod antennas are very sensitive and lowering the sensitivity is usually needed when approaching the target. If a strong interfering magnetic field from a stationary source prevents operation, rod antennas can be rotated to an angle that effectively cancels the interference. Such sources include power lines, wiring and heavy equipment in an industrial site, electric trains, subways, and trams including their tracks and wiring. When the target is exposed and accessible, it is usually easier to use a proximity antenna. LA43 Proximity antenna has a flat, round, insulated bottom that is set or moved on the target surface, duct, wire, cable, or cable bunch. A narrow signal minimum can often be detected right above the target, especially if the distance is short. If the target surface is sensitive it is recommended to use a piece of soft cloth between the antenna and the surface to prevent scratches. Although a proximity antenna is relatively insensitive to distant sources of interference, its limited range makes it ineffective when locating buried cables or ducts with the smallest sondes. In those cases, use a rod antenna instead.KA43 Capacitive antenna is typically moved above exposed wires or wire pairs, or above wire terminals. The very tip of the antenna is the active point which senses the signal generator voltage on the target. A looped, shorted, or loaded wire cannot be detected with a capacitive antenna. Use a proximity antenna in those cases.
Locating ducts with a sonde
Sonde is a small, independent transmitter device that generates a magnetic field that oscillates at a specific frequency depending on the sonde type. Ducts, pipes, tubes, cavities, or their blockages can be located by inserting a sonde inside of them and then locating the sonde. Objects made of a non- conductive material can be located with a 33 kHz sonde and either a Rod antenna SA43 or a Proximity antenna LA43. Conductive ducts made of cast iron or stainless steel should be located with a 512 Hz sonde and SA05 Rod antenna making use of their low

Exact longitudinal location: Hold CL43 vertically and approach the sonde in the duct. To define the exact longitudinal location of the sonde, pinpoint the signal minimum line. It runs transversely (90°) against the direction of the duct. Mark the minimum line to the ground.
Exact transversal location: Turn CL43 to a horizontal position and hold it transversely (at a 90° angle) above the minimum line. Keep the antenna in this position and height and move left and right on the minimum line to find the strongest signal you can get. Signal peak pinpoints the exact sonde location underground.

Sonde depth: Hold the CL43 horizontally and transversely (in 90° angle) to the minimum line. Move CL43 further ahead to the sonde nose direction until another minimum is detected. Sonde depth h is the distances of the two minimums multiplied by 1.4.
Canceling interference: To locate a sonde close to an interfering cable, duct or rail with a rod antenna: Rotate CL43 parallel to the source of interference (usually horizontal) thus minimizing its effect. Keep this attitude and move CL43 towards the sonde until a signal maximum is detected .

Using signal generators
A cable locator detects the magnetic or electric field which has been induced to a cable or wire using a signal generator. Locating is often affected by other nearby conductors and ducts. In order to use a signal generator with CL43, select a signal generator that outputs 33 kHz (32768 Hz) frequency. For safe and proper connection refer to signal generator information for use.

Locating buried cables
Connect a signal generator between the located cable and ground or use an inductive coupler. Use SA43 Rod antenna to track the cable route starting at the signal generator. Pinpoint the cable’s exact location using the minimum locating method. Tilt CL43 to a 45° angle and find a second minimum. Distance between the first minimum A and the second minimum B equals to cable depth .

Locating cables and wires at a short distance

Connect a signal generator between the located cable and ground, use an inductive coupler or connect between different cable conductors. Use LA43 Proximity antenna to track the cable or wire route starting at the signal generator. Pinpoint the cable using the minimum locating method. If the signal current return path is within the same cable, locating range will be reduced. Also, as conductors are often twisted inside the cable, the signal strength often appears to go up and down or minimum zigzags from side to side.
CAUTION: If there are other cables or wires nearby, the signal may often be detectable on those too. Carefully scan which cable or wire gives the strongest signal. Using a low sensitivity may be necessary to distinguish between similar signal levels.

Locating cable faults
Cable faults are sometimes difficult to locate. It is possible that a failed cable has multiple faults which may or may not be of different types. Repairing some faults may be necessary before the rest can be found. Fault properties can change during locating making work even more difficult. Completely disconnect all conductors and any possible shielding at both ends of the faulty cable and use a multimeter to determine the type of the fault: short circuit, open circuit or a combination of faults. If necessary, refer to the multimeter information for use. Connect a signal generator between all the conductors of the located cable and ground. Locate the cable using methods described in sections 3.4 and 3.5 and mark the entire cable route. Short circuit: Connect a signal generator between the shorted conductors and leave other conductors unconnected. If received signal strength allows, use the LA43 Proximity antenna. If the signal is weak, use the SA43 Rod antenna. Starting from the signal generator, note any sudden changes in signal strength along the cable route. Typically received signal strength increases before the short and drops suddenly at the short. If possible, repeat from the other cable end. Open circuit: To reduce labor when the cable is very long, measure the capacitances between the cut conductor and ground and an intact conductor and ground with a multimeter. The approximate fault distance from the cable end is the first value divided by the second value multiplied by the cable length. If necessary, refer to the multimeter information for use. Connect a signal generator between the ground and the faulty conductor. Ground all the other conductors and shields. It may be necessary to use the signal generator at a high output level. Refer to signal generator information for use if necessary. If received signal strength allows, use LA43 Proximityantenna. If the signal is weak, use the SA43 Rod antenna. Starting from the signal generator, note any sudden changes in signal strength along the cable route. Typically received signal strength decreases just before the open fault and may slightly increase after it. If possible, repeat from the other cable end.
Identifying circuit breakers, switches, and fuses in low voltage network
When there is a need to locate the circuit breaker, switch or fuse that feeds a cable, connect a signal generator between the live and neutral conductors of the cable. Refer to signal generator information for use for safe and proper connection. Use the LA43 Proximity antenna and scan all suspected circuit breakers, fuses, or switches.
CAUTION: The signal may be detectable at several devices. The correct one will usually have the strongest signal combined with a sharp null and a strong maximum on both sides of the null. Using a low sensitivity may be necessary to distinguish between similar signal levels. Opening the correct circuit breaker or switch or removing the fuse will considerably lower the received signal strength.
Locating and identifying open ends of wires
Connect both signal generator outputs to a wire pair or between a single wire and ground. Use the KA43 Capacitive antenna and scan as close as possible over the wires or terminals to find the signal maximum. The strongest signal is above the right wire or pair. A minor minimum may be present in the middle of the pair. Due to cross talk, the signal can be received elsewhere too but weaker.
