Circuitracer ? Instructions
Made in the
United States of America
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.
Description
MODEL 35100 VOLTAGE AND CONTINUITY TESTER
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.
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.
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.
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.
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.
