Product Description 11. Signal indicator. Radiating arc graphics appear when Transmitter is send- ing a signal. On the Receiver, the number of arcs corresponds to the re- ceiver 'sensitivity level'. 12. Bar-graph shows signal level. #NAS100035; r. AA/71038/71038; en-US...
Transmitter Operating Modes 4.1 Transmitter TEST and TRANSMIT Mode When the power is on, the Transmitter defaults to the Test mode. In this mode you can measure AC or DC voltage with the test leads. In this mode you can also transmit a signal.
Receiver Operating Modes 5.1 Automatic Detection Mode When the power is on, the Receiver defaults to the auto detection mode where it can trace the high frequency transmission signal at the highest sensi- tivity. The Receiver responds to the detected signal with a variable tone (550 Hz ~ 1.6 kHz) and a bar-graph indication.
Applications 6.1 Single-pole applications 6.1.1 Locating Opened Wires Figure 6.1 Locating opened wires. Diagram shows one transmitter in a fixed location and one Receiver being used in two locations. The Receiver position on the left is detecting a sig- nal, while the Receiver position on the right is not detecting a signal. 1.

Applications Figure 6.2 Locating and Tracing Lines and Receptacles 1. Connect the red, positive (+) terminal to the live (hot) conductor. 2. Connect the black (COM) terminal to earth ground. When working out- doors, you can use the supplied ground spike for an earth ground connection.
Applications 6.2 Two-pole Applications 6.2.1 Tracing Connections Figure 6.3 Matching connected points in a circuit. 1. Connect the supplied Socket Adaptor to the Transmitter and plug the AC connector into an AC receptacle. 2. The Transmitter can now measure the voltage of the mains and transmit the signal through the mains.
Applications 6.2.2 Broken Line Detection Figure 6.4 Two Examples of Broken Line Detection (the top diagram shows a two-conductor test, while the bottom diagram shows a single-conductor test). Diagrams show one transmit- ter in a fixed location and one Receiver being used in two locations. On the top diagram, the Receiver position on the left is detecting a signal, while the Receiver position on the right is not detecting a signal.
Applications 6.3 Other Applications 6.3.1 Tracing an Underground Circuit WARNING The circuit under test must not be live. Figure 6.5 Tracing Underground Circuits 1. Connect the Transmitter’s positive (+) terminal as shown in the diagram. 2. The Transmitter’s COM terminal must be correctly connected to earth ground.
Applications 6.3.3 Detecting Faults in a Floor Heating System (using two kits) WARNING The circuit under test must not be live. Figure 6.6 Detecting Faults in a Floor Heating System 1. The right end of the circuit is connected to the Transmitter that is sending an ‘x’...
Applications 6.3.4 Non-Contact Voltage Detection Figure 6.7 Non-Contact Voltage Detection 1. The circuit under test must be live and connected to the mains. 2. Set the Receiver to the U mode. 3. Hold the tip of the Receiver close to the source of AC voltage to test. 4.
Applications 6.3.5 Using the Ground Spike TR A N SM I TTER C AT I I I 450V Figure 6.8 Earth Ground Spike 1. Refer to the accompanying diagram. 2. In applications that require an earth ground connection, you can use the supplied ground rod (spike) for convenience.
Maintenance 7.1 Battery Replacement (Transmitter) When the battery symbol appears and flashes on the LCD, replace the bat- teries as follows: Figure 7.1 Replacing Transmitter Batteries • Disconnect the test leads from the Transmitter and switch off the Transmit- ter’s power. •...
Maintenance • Open the battery compartment by first removing the compartment screw (2) and then removing the cover (1). • Replace the batteries (1.5 V AAA x 6) observing correct polarity (3). • Replace the compartment cover securely before operating the Receiver. 7.3 Cleaning and Storage WARNING To avoid electrical shock or damage to the instrument, do not allow water to access the...
