TRANSMITTER OPERATING MODES
Transmitter TEST and TRANSMIT Mode
In TEST mode (default), you can measure AC or DC voltage from
12 V to 450 V AC / DC with the test leads. You also transmit a sig-
nal: Press the TEST/STOP button to allow the Transmitter to send a
signal. Press the TEST/STOP button again to switch the signal OFF.
Transmitter LEVEL Select Mode
Press the LEVEL button, the ‘LEVEL’ text will flash. Use the arrows
to select the strength of the transmission signal (level: 1~3). Press
LEVEL again to return to the TEST Mode.
CODE Selection Mode
Codes are used to differentiate two or more Transmitters that can
be used to detect a break in a circuit. Long press the CODE button,
the ‘CODE’ text will flash. Use the arrows to select the code for the
transmission signal (F, E, H, d, L, C, O, A). Press CODE again to re-
turn to the TEST Mode.
RECEIVER OPERATING MODES
Automatic Detection Mode
In Auto Detection mode (default) you can detect the high frequency
transmission signal at the highest sensitivity. The Receiver re-
sponds to the detected signal with a variable tone (550 Hz ~ 1.6
kHz) and a bar-graph indication. The stronger the signal, the higher
the frequency of the tone and the more bars on the graph.
#NAS100049; r. AA/70188/70188; en-US 7

The Receiver displays SIG (Signal) and the numeric value of the re-
ceived signal strength. The optional transmission Code, sent from
the Transmitter, is also displayed.
Manual Detection Mode
Press the Mbutton and select the signal sensitivity level manually
(8 steps) using the arrows. Press Magain to return to the Auto-De-
tection mode.
Non-Contact Voltage Detection Mode (UAC)
Press the UAC button. In this mode you can detect AC voltage with-
out having to make contact with the circuitry. See the dedicated
section later in this document.
SINGLE-POLE APPLICATIONS
Locating Opened Wires
1. Refer to Figure 1 in the Application Illustrations section.
2. Connect from the red, positive (+) terminal to a single conductor.
3. Connect from the black (COM) terminal to earth ground.
4. If there are additional conductors in the same conduit or cable,
they will also have to be connected to earth ground. For conven-
ience, use the supplied ground rod if testing outdoors.
5. The Receiver can now detect the location of the wiring fault.
Locating and Tracing Lines and Receptacles
WARNING: Do not perform this test on a live circuit.
1. Connect from the red, positive (+) terminal to the ‘hot’ conductor.
2. Connect from the black (COM) terminal to earth ground. For
convenience, use the supplied ground rod if testing outdoors.
3. Refer to Figure 2 in the Application Illustrations section for
examples.
TWO-POLE APPLICATIONS
Locating and Matching Connected Points in a Circuit (120 V)
1. Connect the supplied AC 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.
3. The Receiver can then trace the mains and determine if a re-
ceptacle is connected on the same line, if another receptacle or
breaker is connected on the same circuit.
#NAS100049; r. AA/70188/70188; en-US 8

4. Refer to Figure 3 in the Application Illustrations section for
examples.
Broken Line Detection
1. Method 1: Connect both terminals of the Transmitter, one to
each wire, at one end of the line. At the other end of the line,
connect the wires together.
2. Method 2: Connect both terminals of the Transmitter to each
end of a single wire in the line.
3. The Receiver can now determine the position of the broken wire
in the signal line in the wall or floor.
4. Refer to Figure 4 in the Application Illustrations section for
examples.
NON-CONTACT AC VOLTAGE DETECTION
1. The circuit under test must be live and connected to the mains.
2. Set the Receiver to the UAC mode.
3. Hold the tip of the Receiver close to the source of AC voltage.
4. The mains AC voltage detected by the Receiver in the UAC
mode only indicates whether or not the circuit is live.
5. While searching for the ends of the supply lines, the lines must
be connected separately, one by one.
6. The number of bars on the bar graph and the audible tone’s
pitch increases as the strength of the detected signal increases.
The closer the sensor is to the source of voltage, the stronger
the signal detection.
7. Refer to Figure 5 in the Application Illustrations section for
examples.
EARTH GROUND ROD (SPIKE) USE
1. In applications that require an outdoor earth ground connection,
use the supplied ground rod (spike) for convenience.
2. Refer to Figure 6 in the Application Illustrations section.
3. Carefully drive the supplied rod into the ground at the test area.
4. Connect the test leads and set up tests as shown in the applica-
tion instructions provided in the accompanying sections.
