AMPLIFIER PROBE
FEATURES
● The Amplier Probe is designed to identify and
trace wires or cables within a group without
damaging the insulation.
● Works with any Tone Generator to identify wires.
● Volume control for increased sensitivity and
adjustable to suit work environment.
● Recessed ON/OFF button prevents battery drain.
● Power supply is in any 9V battery with a life of
approximately 100 hours.
● A plug receptacle is provided for head set or hand
set.

INSTRUCTIONS
● Connecting the tone generator.
In terminated working cables :
Connect one test lead to a terminated wire and the
other test lead to earth or equipment ground.(See
gure 2)
In unterminated or non-working cables :
Connect one test lead to an unterminated wire and
the other test lead to another unterminated wire.
● Depress the round on/off spring-loaded button of
the amplier probe. The volume control switch can
be adjusted to suit the environment. Volume can be
increased to overcome noise, or decreased to
reduce interference.
● Touch the tip of the amplier probe to the insulation
of each suspect conductor.
● Reception of tone will be loudest on the subject
wire.
● The plug receptacle is provided for connecting to a
head set or hand set.
MAINTENANCE
The amplier probe is maintenance free except for
battery replacement. Remove the screw from the
battery compartment, replace the 9V battery and
reassemble.
Warranty limited solely to repair or replacement; no
warranty of merchantability, tness for a particular
purpose or consequential damages.

FEATURES
● Red and black test leads with a standard 4
conductor modular cord and plug.
● A 3-position toggle switch controls the modes
of operation and two bi-colored LEDs display line
polarity for Lines 1 and 2.
● The tone and continuity (cont.) test functions are
only applied to Line 1 using the modular plug.
● A tone selector switch located inside the test set is
provided for choosing either a fast dual alternating
tone or a slow dual alternating tone.
(CAUTION : DO NOT CONNECT TO AN ACTIVE AC
CIRCUIT EXCEEDING 24V IN THIS MODE.)

INSTRUCTIONS
All of the following tests can be performed by using
the red and black test leads or the modular plug.
NOTE : When using the modular test plug, the
polarity test function applies to Lines 1 and 2. The
continuity and tone functions ONLY apply to Line 1.
●Polarity test ; identifying tip & ring (switch to
"off")
1. Connect the RED test lead to the side of one line
and the BLACK lead to the side of another line.
2. The LED will glow "GREEN" when you connect
the RED test lead to the RING SIDE of the line.
3. The LED will glow "RED" when you connect the
RED test lead to the TIP SIDE of the line.
●Identifying line condition (switch to "off")
1. Connect the RED test lead to the RING SIDE of
the line and the BLACK to the TIP.
2. Watch the LED :
1.1 A BRIGHT "GREEN" LED indicates a CLEAR
line.
1.2 A DIM "GREEN" LED indicates a BUSY line.
1.3 A BRIGHTLY FLICKERING "GREEN and
RED" LED indicates a RINGING line.

●Verifying lines (switch to "off" then "cont")
1. Dial the line to be veried.
2. While the line is ringing, connect the RED lead
to the RING SIDE of the line and the BLACK to
the TIP.
3. In the "OFF" position, the indicator lamp will
icker "RED and GREEN" when the test leads
are connected to the subject pair.
4. If you switch the test set to "CONT", it will
terminate the call on the subject line.
●Sending tone (switch to "tone")
CAUTION : DO NOT CONNECT TO ANY ACTIVE
AC CIRCUIT EXCEEDING 24V IN THIS MODE.
1. Connect the test leads to the pair, or attach one
lead to ground and one lead to either side of the
line.(See gure 4)
2. A fast dual alternating tone, or a slow dual
alternating tone can be selected from the switch
inside the tone generator.
3. Probe the suspected wires with the amplier
probe. Reception of tone will be strongest on
the subject wire. In case of ready access to bare
conductors, a hand set or head phone may be
used to receive the tone.

-7-
●Testing continuity (switch to "cont")
CAUTION : DO NOT CONNECT TO ANY ACTIVE
AC OR DC CIRCUIT IN THIS MODE.
1. Connect the test leads to the subject pair.
2. Use "cont" position.
3. A bright "GREEN" light indicates continuity. The
LED will not glow if the line resistance exceeds
12kΩ.
●Testing continuity using tone (switch to "tone")
CAUTION : DO NOT CONNECT TO ANY ACTIVE
AC OR DC CIRCUIT IN THIS MODE.
1. Connect the test leads to the subject pair.
2. Use a handset or headset at the remote end and
touch the wire end(s) with the clip lead(s).
3. Reception of tone is an indication of continuity.
●Modular testing
All above tests are available through the modular
plug for line 1 only - red and green wires.

-8-
●Coax testing
1. To test unterminated coax, connect red to outer
shield and black to center conductor or red to
outer shield and black to ground.
2. To test terminated coax, connect red to
connector housing and black to center pin or
red to connector housing and black to ground.
MAINTENANCE
BATTERY REPLACEMENT INSTRUCTIONS
1. Separate the case, install a fresh 9V battery and
reassemble. DO NOT OVER TIGHTEN.
2. Warranty limited solely to repair or replacement;
no warranty of merchantability, tness for a
particular purpose or consequential
damages.
