150R/T Operator’s Manual Locate - 26 Active Location Active Location Setup Follow setup procedures for the type of locating you will be doing: direct connection, induction clamp, or broadcast induction. Always check receiver battery level at startup. See “Controls” on page 13. Direct Connection Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
150R/T Operator’s Manual Locate - 27 Active Location Induction Clamp Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment. NOTICE: Electric shock or equipment damage can result if transmitter is connected to live cable. Contact qualified utility personnel and follow all standards and requirements for disconnecting and grounding lines. To set up transmitter for use with induction clamp: 1. Plug cable into transmitter (1). 2.
Locate - 28 150R/T Operator’s Manual Active Location Broadcast Induction To set up transmitter for broadcast induction: 1. Remove cable, stake, clamp and any other metal objects from transmitter. 2. Place transmitter parallel to and directly above suspected line as shown. Note: Transmitter must be parallel to object, as shown, in order to produce the best signal. 3. Turn on transmitter. 4. Check battery level indicator.
150R/T Operator’s Manual Locate - 29 Active Location Technique IMPORTANT: Follow steps 1-3 for all types of active location. For reference, the illustration above shows direct connection method. If using broadcast induction, ensure that transmitter is in line with and above suspected line, as shown on previous page. 1. Walk in an arc approximately 25’ (7.5 m) around utility to be located. 2. Hold the receiver so that the handle points toward the transmitter, as shown. 3.
Locate - 30 150R/T Operator’s Manual Active Location 4. Rotate the receiver to determine which direction the line runs. IMPORTANT: Receiver indicates the best signal when the handle lines up with the target line. 5. Trace the line and mark with appropriate flags or paint.
150R/T Operator’s Manual Locate - 31 Active Location Mark the Line Sweep, focus, and trace all detected signals in the area. Mark line paths with colored paint or flags. See the chart below for standard color markings for line locations. Utility Color Marking Symbol electric red -E- gas/oil yellow -G- communications orange -TEL- or -TV- water blue -W- sewer green -S- Special Situations Situation What to try Signal is lost. Walk in a circle to detect a tee or bend in the line.
Locate - 32 150R/T Operator’s Manual Passive Location Passive Location Setup Follow setup procedures for the type of locating you will be doing. Always check receiver battery level at startup. See “Controls” on page 13. NOTICE: Lines with no AC current flowing through them are hard to detect and may be hazardous because they may still have voltage potential. To locate, turn on an appliance to cause current to flow and use active search methods.
150R/T Operator’s Manual Locate - 33 Passive Location Sweep the Site Search the site by walking a grid pattern while holding receiver close to the ground. NOTICE: Keep receiver level. Focus the Signal Move receiver over detected signal to find best signal response. If using a peak antenna mode, rotate receiver until signal is best. Best signal indicates line direction. NOTICE: Keep receiver level.
Locate - 34 150R/T Operator’s Manual Passive Location Antenna Mode Configuration All 150R receiver units can locate in either peak or null mode. Rotate receiver 90° to locate using other antenna mode. When rotated 90°, a peak configured receiver will function as a null receiver or a null configured receiver will function as a peak receiver. IMPORTANT: The operator will not be able to view display in other antenna mode.
150R/T Operator’s Manual Locate - 35 Passive Location Trace the Line Walk along the suspected path while moving the receiver from side to side across the area. IMPORTANT: Keep receiver handle parallel to the suspected line path.
150R/T Operator’s Manual Locate - 36 Passive Location Mark the Line Sweep, focus, and trace all detected signals in the area. Mark line paths with colored paint or flags. See the chart below for standard color markings for line locations. Utility Color Marking Symbol electric red -E- Special Situations Situation What to try Signal is lost. Walk in a circle to detect a tee or bend in the line. Signal varies from low to high and is unstable. Mark as a hand-dig area.
150R/T Operator’s Manual Locate - 37 Beacon Location Beacon Location Trace metallic or non-metallic pipes or conduits by locating and following a beacon signal. IMPORTANT: Large metal objects and other signals (such as railroad signals or overhead power lines) will distort signal. Setup To set up for beacon location: 1. Follow instructions for installing beacon battery. 2. Turn on receiver to ensure that beacon is functioning properly. 3. Attach beacon to plumber’s snake or flex rod. Technique 1.

150R/T Operator’s Manual Locating Concepts - 40 Signal Type Signal Type The 150R can detect three types of signals: • Active signals that are placed on a target line with a transmitter. • An active signal from a beacon. • Passive signals that reside on the target line. Active There are three ways to place active signals on a target line with a transmitter: • Direct connection (preferred method) requires a connection to be made directly onto target line.
150R/T Operator’s Manual Locating Concepts - 41 Antenna Configuration Antenna Configuration The 150R receiver is available with one of two antenna configurations: peak or null. Peak Uses a horizontal antenna to detect signal. Response is highest at strongest signal. Null Uses a vertical antenna to detect signal. Search width is narrower than peak. Response is lowest when receiver is over the line.
Locating Concepts - 42 150R/T Operator’s Manual Common Signal Problems Common Signal Problems Distortions in the electromagnetic field around a line can affect location accuracy. Tees, bends, parallel lines, crossing lines, or large metallic objects can distort signals. IMPORTANT: If target depth and location are critical, confirm by hand-digging or vacuum excavation.

150R/T Operator’s Manual Service - 44 General Care General Care Under normal operating conditions, receiver and transmitter need only minor maintenance. Following these care instructions can ensure longer equipment life: • Do not drop the equipment. • Do not expose the equipment to high heat (such as in the rear window of a vehicle). • Clean equipment with a damp cloth and mild soap. Never use scouring powder. • Do not immerse in any liquid. • Inspect housing daily for cracks or other damage.
150R/T Operator’s Manual Service - 45 As Needed Transmitter Unit Change Batteries Use six C-cell alkaline batteries in transmitter. 1. Open battery cover. 2. Insert batteries as shown. IMPORTANT: Do not mix new and used batteries. 3. Close and tighten battery cover. 4. Check operation. If battery light is flashing when unit is turned on, then one battery is incorrectly installed or batteries are weak.
Service - 46 150R/T Operator’s Manual Self Test Error Messages Self Test Error Messages A receiver self test may return an error message for four reasons: low sensitivity, a failed channel, noise present, or gain test failure. Low Sensitivity A low sensitivity message will always appear together with a “noise” screen. This could indicate a problem with the antenna, or it could simply be the result of attempting to test in a noisy environment. Try the test again later, preferably in a different location.
