Circuitracer
®
Instructions
General Guidelines
The Menda Circuitracer
®
is designed for use on the
assembly line or in the field. The “light at the tip” of the
Circuitracer
®
makes it unnecessary for operators to
move their eyes from the point of contact. This feature
effectively allows the operator to move quickly from
point to point without the danger of slipping from one
contact to another. The Circuitracer
®
line was created
as a supplement to delicate, expensive meters. Menda’s
complete line of Circuitracer
®
s allow operators to test for
continuity, shorts, grounds or the presence of voltage
quickly, effectively and economically.
Made in the
United States of America
Description
MODEL 35100 VOLTAGE AND CONTINUITY TESTER
MODEL 35135 AUDIBLE CONTINUITY TESTER
The model
35135
is an audible version of the model
35100
Circuitracer
®
designed for measuring continuity.
The
35135
emits a strong (70db at 20cm) audible signal
when a complete circuit of less than 50 ohms resistance
is between the clip and probe. The probe lead accepts
a tip with a 10-32 thread. This audible Circuitracer
®
comes equipped with 3’ of lead wire, a probe tip in
the nose, alligator in the lead, and two AAA batteries.
The
35135
measures continuity from 0-50 ohms with
a probe voltage of 3V at 15mA maximum. For detailed
specifications, please see
35135’s
technical drawing.
The model
35100
Circuitracer
®
is a three-in-one test
lab. The Circuitracer
®
comes with the standard one inch
probe tip and three feet of lead wire terminated by an
insulated ground clip. The
35100
will also use any probe
tip with a 10-32 thread. The model
35100
tester includes
a low voltage lamp for measuring 1-3 volt powered
circuits and a neon cartridge for measuring 60-600 volt
powered circuits. Batteries for measuring continuity from
0-10 ohms are not included. The probe voltage on the
model
35100
is 3V at 270mA maximum. For detailed
specitications, please see
35100’s
technical drawing.
Assembly
ASSEMBLY OF MODEL 35100 FOR TESTING
UNPOWERED CIRCUITS
When assembled with two AAA batteries in the handle,
the model
35100
circuitracer will become a self powered
continuity tester, able to measure continuity between
0-10 ohms.
Continuity tester assembly.
MODEL 35130 CONTINUITY TESTER
The
35130
Circuitracer
®
is the continuity only version
of the model
35130.
The
35130
can measure continuity
from 0-10 ohms. The model
35130
comes equipped with
a low voltage TL-3 lamp, two AAA batteries, a probe tip
and 3’ of lead wire terminated with a standard alligator
clip. The nose probe will accept all probe tips with a
10-32 thread. Probe voltage is 3V at 270mA maximum.
For detailed specifications, please see
35130’s
technical
drawing.
1. Unscrew transparent probe window from handle.
2. Insert the incandescent lamp into the spring- connector
and drop into the probe window with spring touching
the back end of the probe. Ensure that there is no
debris between the lamp and the spring connector.
Center contact of lamp will point toward threaded end
of probe window.
3. Turn handle on wire so that wire will retract to bottom
of handle and insert two AAA batteries in handle.
4. Screw probe window onto handle. Touch clip to probe
end to be sure Circuitracer
®
is working properly.

ASSEMBLY OF MODEL 35100 FOR TESTING
POWERED CIRCUITS
When assembled without batteries, the model 35100
circuitracer can be used to test powered circuits.
1. Unscrew probe assembly.
2. Insert battery(s) into handle so that positive end of
battery(s) points towards probe window.
3. Screw probe window onto handle. Touch clip to probe
end to be sure circuitracer is working properly.
Troubleshooting Tip:
Please check to verify the battery is working. If the
battery is working properly, please check the transparent
probe window. If there is debris or small particles it may
interfere with the connection. Use compressed air to
blow any debris or particles off the transparent probe
window. You can then replace the battery back in and
test the circuitracer again.
Assembly for testing 1-3 volt circuits.
1. Unscrew transparent probe window from handle.
2. Insert the incandescent lamp into the spring-connector
and drop into the probe window with spring touching
the back end of the probe. Center contact of lamp will
point toward threaded end of probe window.
3. Push the lead wire and pull down slightly until three
pointed washer rests on ledge inside of handle. Hold
tension on back of lead wire with hand as illustrated
above to keep assembly in place.
4. Screw transparent probe window back on handle so
that the center contact of lamp makes contact with
lead wire.
5. Test lamp by applying correct supply voltage across
clip and probe before starting circuit testing.
