If damage is discovered, file a claim with the carrier at once. Prepare a detailed description of the damage and notify AVO International. This instrument has been thoroughly tested and inspected to meet rigid specifications before being shipped. It is ready for use when set up as indicated in this manual. General Information Thanks for purchasing the BIDDLE L1050 Portable Locator. The portable locator will help you detect and trace the routes of buried power cables, CATV cables, gas and water pipes, sewer lines, telephone cables, and fiber-optic cables. The transmitter applies a tracing signal onto a cable or pipe. The receiver detects the tracing signal and indicates how strong it is. You can locate the path of a buried pipe or cable by following the tracing signal. Supplied Components 1.Transmitter unit (built into carrying case) 2.Receiver unit 3.Red/black test cord 4.Ground rod 5.Instruction Manual 6.Eight AA-size alkaline batteries 7.Eight D-size batteries Optional Flexible Coupler Preparation for Use Remove the receiver from the case, and turn it face-down. Locate the battery compartment on the back of the receiver. Install the eight AA-size batteries as marked on the case. 2 The transmitter battery compartment is situated under the receiver storage well, in the bottom of the case. Install the eight D-size transmitter batteries as marked on the case. Section 2 Safety The L1050 Portable Locator and the recommended operating procedures have been designed with careful attention to safety; however, it is not possible to eliminate all hazards from electrical test equipment or to foresee every possible hazard that may occur. It is therefore essential that the user, in addition to following the safety rules in this manual, also carefully consider all safety aspects of the test before proceeding. Safety is the responsibility of the user. Use suitable barriers, barricades, and warnings to keep people not actually engaged in the test at a safe distance. Make sure that no one can make contact with energized parts of the test equipment and the specimen under test. Treat all terminals of power equipment as a potential electric shock hazard. There is always the possibility of voltages being induced at these terminals because of proximity to energized high-voltage lines or equipment. Always turn the transmitter power off before touching any terminals. Always disconnect test leads from the cable under test before attempting to disconnect them from the portable locator. Never connect the test leads to a cable that does not have a safety ground strap in place. Never disconnect the test leads from a cable that does not have a safety ground strap in place. The safety ground connection must be the first made and the last removed. Any interruption of the grounding connection can create an electric shock hazard. Do not use this equipment to fault locate on any cable which is likely to be near enough to an energized cable to allow a burn through of the insulation of the energized cable. This situation may occur when the cables are located in a common trench, duct or tray (for example, three- phase systems). Do not operate the equipment with protective covers removed. Operation without the protective covers presents an electric shock hazard. Use all practical safety precautions to prevent contact with energized parts of the equipment and related circuits. 3 Use the recommended grounding and connection procedures. Make sure that the equipment is grounded properly. Any interruption of the grounding connection can create an electric shock hazard. Refer to IEEE 510-1983 IEEE Recommended Practices for Safety in High-Voltage and High-Power Testing for additional information. Do not use the portable locator or its accessories with any device or for any purpose other than as specifically described in this manual. Misuse of this equipment can be extremely dangerous. Never connect the portable locator to energized equipment. Do not use in an explosive atmosphere. If the portable locator is operated in accordance with the safety precautions described, and if all grounds are correctly made, rubber gloves are not necessary. As a routine safety procedure, however, some users require that rubber gloves be worn, not only when making connections to the high-voltage terminals but also when manipulating controls. AVO International considers this an excellent safety practice. Users of high-voltage equipment should note that high-voltage discharges and other sources of strong electric or magnetic fields may interfere with the proper operation of heart pacemakers. Personnel having heart pacemakers should obtain expert advice on possible risks before using this equipment or being close to equipment while it is in operation. 4 Section 3 Specifications Receiver Operating frequency:82.315 kHz and 815 Hz, switch selectable Antenna mode:Peak responding horizontal antenna Operating and storage temperature range:-4 to +133F (-20 to +55C) Battery type:Eight AA-size alkaline cells Battery life:120 hr on 815 Hz and 100 hr on 82.315 kHz Dimensions:13 x 3 x 3 in (33 x 7.6 x 7.6 cm) (L x W x H) Weight:1 lb, 4 oz (0.568 kg) Transmitter Operating frequency:82.315 kHz and 815 Hz Output power:100 mW directly connected 100 mW inductively coupled Battery type:Eight D-size alkaline cells Battery life:150 hr Operating and storage temperature range:-4 to +133F (-20 to +55C) Dimensions:17 x 7.5 x 6.5 in.

The methods under each heading are listed in order of preference. The first method is easiest, and usually gives the best results. The second method listed is next best, and so on. After selecting the locating method, turn to the page that tells how to connect the equipment. ELECTRICAL CABLE AND CABLE TV (CATV) Multiple Grounded Circuit Flexible Coupler Connection Inductive Connection Direct Connection GAS AND WATER PIPE Continuously Grounded Circuit Flexible Coupler Connection TELEPHONE CABLE Multiple Grounded Circuit Telephone Direct Shield Connection Telephone Direct Pair Connection FIBER-OPTIC CABLES Multiple Grounded Circuit Inductive Connection Telephone Direct Shield Connection NOTE: The flexible coupler and inductive connection methods require using the 82 kHz high frequency setting. 7 Multiple Grounded Circuit This method uses the existing ground points that are already exposed and available to you. It is not necessary to disconnect the service. The range of operation is up to 0.5 mi (0.8km). Connect as shown in Figures 3, 4, and 5. Connect the red test cord to an existing ground point. Place the ground rod approximately 10 ft (3 m) from this point, at an angle of 90 degrees to the buried cable or pipe. Push the ground rod into the ground 8 to 10 in. (20.3 to 25.4 cm). Connect the black test cord to the ground rod. Plug the red/black test cord into the DIRECT CONNECT jack. Set the 815Hz/OFF/82kHz switch to the 815 Hz position. The ON indicator will start blinking.

The operating range is shorter than for direct connection methods. The tracing signal can be affected by neighboring cables and pipes. Neither the red/black test cord nor the ground rod are needed for this method. Loop the flexible coupler around the cable and connect the two ends. It is important to connect the flexible coupler around the cable you want to trace, as shown in Figure 6. Connecting it around a commonly bonded cable (dashed line in the figure) will cause the tracing signal to be weaker. The range will be shorter, and you may have trouble telling one cable from another. Plug the flexible coupler test cord into the DIRECT CONNECT jack. Set the 815Hz/OFF/82kHz switch to the 82 kHz position. The ON indicator will start blinking. Turn to Section 5, ?Locating the Cable or Pipe.?

No test leads are needed. When the cable or pipe has neither good insulation nor nonconductive coating, the operating range will be very short.
