Thank You
Thank You...
for purchasing Power Probe’s Scream’N Continuity Tester
(SCT). We made it
of working with weak sounding continuity testers. The
SCT volume is adjustable so you can make it scream, or
adjust it for quieter work environments as well. Your new
SCT emits two distinct tones enabling you to differentiate
between circuits above or below 10 ohms. The SCT also
emits a warble tone when it detects over 6 volts.
The SCT has high quality gold plated 4 mm banana jacks
on both the tip and at the end of the green lead ensuring
compatibility with all your standard 4mm plugs, piercing probes, test leads, etc. The 4mm jacks also make connecting your leads and piercing probes a snap. The built
in headlights light up the probe area, thus eliminating the
need for a fl ashlight.
The 10 foot long green lead keeps everthing within reach.
Should you fi nd the need for a longer lead we have included
a 10 foot green extension lead. The SCT is powered by two
AA batteries. The automatic shut-off maximizes battery life.
Safety Tip
Before performing any electrical test Power Probe strongly
recommends you read this instruction booklet carefully.

Power-On SCT:
There are three ways to turn the SCT on:
1. Touch the tip to the green lead
2. Press the volume button
3. Press the light on-off button
Power-Off SCT:
• The SCT will shut down automatically in 5
minutes if not used.
• To shut down the SCT manually, press and
hold both the “volume button” and the
“light on-off button” simultaneously
for 1 second.

Headlights
The headlights can be turned on and off by pressing the
light on-off button.
Adjustable Volume Levels
By repeatedly pressing the volume button on the SCT
you will cycle through low, medium, and Scream’N
loud audio levels. The Scream’N setting emits a signal
of 100db which can easily be heard even in the noisiest
environments.
Probe Tip & Auxiliary Leads/Adapters
The probe tip of the SCT can be removed by pulling it
outward. The front end of the SCT is a standard 4mm
Gold plated banana jack. This enables you to connect
other 4mm banana plug leads and accessories into it.
Low Battery Warning
When the battery voltage drops below the operating
range, you will hear a series of 3 beeps occurring in 5
minute intervals and if the headlights are on they will
turn off to maximize battery life. (To replace battery
see page 9)

Application
Continuity Testing
When you plan to test continuity of a circuit it
is best to fi rst isolate the circuit. This eliminates
backfeed from parallel circuits which can lead to
a misdiagnosis.

Tones
The three tones of the SCT alert you to the
resistance level of a circuit.
1. LOW pitched tone indicates continuity of
a circuit under 10 ohms.
2. HIGH pitched tone indicates continuity
of a circuit over 10 ohms but under
1 K ohms.
3. WARBLE tone indicates a voltage from
6-24 volts.
Low Tone
Testing a Wire for Continuity
When checking continuity of a wire the low pitched
tone should sound indicating a good connection. If
the high pitched tone sounds the circuit resistance
is in excess of 10 ohms and may need closer examination of the connections.
Flex wire to test contact
Wiggle Test
While measuring circuits we suggest you fl ex or
wiggle the suspected wire and listen for a change
in tone. If there is a change in the tone while you
are fl exing or pulling the wire, you have a faulty
connection and should examine it closer and repair
it. A Wiggle Test is a great method to test and pinpoint both intermittent and short circuits.

Relay Testing
The benefi t of having two tones is
that you can determine the relay coil
from the relay contacts by listening
for the high pitched tone when continuity is through the coil and the
low pitched tone when continuity is
across good closed contacts. (The
relay coil must have over 10 ohms
resistance for the high pitched tone
to sound). Typical 12V automotive
relay coil resistance ranges from 50
to a few hundred Ohms.

Voltage Detection
(fi g.1) Connecting the SCT’s green lead to ground and then probing the tip into the positive
side of a component that is not yet activated, will sound off a steady high or low pitched tone.
(fi g.2) When the circuit is activated, a warble tone will sound off and alert you to the presence
of voltage on the circuit.
