INTRODUCTION On jobs ranging from installing a through-the-wall air-conditioner to renovating a house with new wiring and plumbing, it is vital to know the locations of existing electrical cables and wires, as well as those of metal and non-metal pipes carrying water and gas. Without access to the building’s construction drawings, there is no way to be sure that an action as simple as driving a nail into a wall will not produce an electric shock—or far worse.
• The receiver has variable sensitivity, a backlit display, a loudspeaker and a 10-minute Auto Power Off function.

SETUP INSTRUCTIONS INSTALL BATTERIES The CL10 transmitter is powered by one “9V” battery (included). The CL10 receiver is powered by six “AAA” batteries (also included). To install the “9V” battery in the transmitter: 1. Turn the unit over and lift the fold-out stand (Fig. 2, Callout 13) to expose the battery compartment (Callout 14). 2. Remove the one Philips-head screw securing the battery compartment cover and set it aside. 3. Remove the battery compartment cover and set it aside as well. 4.
OPERATING INSTRUCTIONS SINGLE-POLE CIRCUIT APPLICATIONS For all single-pole applications described in this section, the transmitter is connected to only one conductor of a cable or AC line. The return is to ground (earth). In all of the applications in this section, the transmitter sends a digital code and an analog signal at the radio frequency (RF) of 125 kHz through the conductor to ground.

8. When the probe of the receiver passes the location of the cable or line break, both indications of received signal amplitude will show a sharp reduction and then disappear. At this moment, press the MANUAL button on the receiver (Fig. 4, Callout 8) and move the probe slightly back in the opposite direction. 9. With the receiver now in manual cable locating mode, press the ▼ button to begin reducing the receiver’s sensitivity.
Locating a Cable or Line Break Using Two Transmitters Attempts to locate a cable or line break by feeding the transmitter’s signal into a conductor from one end may not succeed if stray electromagnetic fields are present. One way to solve this problem is to attach a second transmitter to the conductor at its opposite end. Additional transmitters (Part No. CL10T) are available from General. For more details or to order, enter “CL10T” in the SEARCH box at www.generaltools.com.
Locating a Blockage in a Non-metallic Pipe The basic procedure used in all of the previous applications also can be used to locate a blockage in a non-conductive (plastic, for example) pipe. In this case, the + terminal of transmitter is connected to a metal tube or piece of flexible conduit thin enough to be fed into the pipe, as shown in Fig. 9. When the signal induced in the receiver drops off sharply, the receiver is directly above the blockage. Locating a Metal Water Pipe Fig. 9.
TWO-POLE CIRCUIT APPLICATIONS For all two-pole applications (U.S. 240VAC) described in this section, you will create a closed circuit by attaching both test leads of the transmitter to the power circuit’s conductors (lines). The exact connection depends on whether the power circuit is live (energized) or dead (de-energized). For live circuits: Connect the transmitter’s + jack to the phase line and the jack to the neutral line.
Identifying the Fuse or Circuit Breaker Associated with an AC Outlet Unlike inexpensive AC-powered circuit breaker finders, the CL10 can identify the breaker associated with an outlet of a de-energized circuit because the CL10’s transmitter is battery-powered. Before proceeding with this application, you should reduce the transmitter’s output Fig. 12. Identifying the fuse or circuit current to a suitable level. Then connect breaker associated with an ac outlet the transmitter to the outlet as shown in Fig.
To counter this effect, consider making the connection shown in Fig. 14. Use of a cable reel can increase the transmitter’s effective radius to 10 ft. or more. USING THE RECEIVER AS A VOLTMETER Fig. 14. Using a cable reel to To use the receiver as a voltmeter: increase the transmitter’s 1. Press the UAC button (Fig. 3, Callout 7). The detection radius text UAC will appear at the bottom left of the LCD. 2. Position the probe near a current-carrying line.

OPERATING & MAINTENANCE INSTRUCTIONS CHANGING BATTERIES When the icon on the transmitter or receiver, or the icon on the receiver begins to flash, it’s time to change the power source of the indicated unit. Before proceeding to change the transmitter’s “9V” battery, power off the unit and all circuits to which it is connected and remove all connecting wires. Detailed instructions for changing the transmitter’s battery and the receiver’s batteries are found on p. 7 of this manual.
To change the fuse (if it blows following expiration of the 1-year limited warranty term), you must open the CL10’s housing. To do so: 1. Turn the unit over and remove the two Philips-head screws at the top corners of the back half of the housing. 2. Remove the one Philips-head screw securing the battery compartment cover to the back. 3. Lift the cover to expose the other two Philips-head screws securing the two halves of the housing to each other. Remove those two screws as well. 4.
WARRANTY INFORMATION General Tools & Instruments’ (General’s) CL10 Cable & Pipe Locator is warranted to the original purchaser to be free from defects in material and workmanship for a period of one year. Subject to certain restrictions, General will repair or replace this instrument if, after examination, the company determines it to be defective in material or workmanship.
