TECHNICAL BULLETIN TB-4005 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. Mendas complete line of Circuitracer s allow operators to test for continuity, shorts, grounds or the presence of voltage quickly, effectively and economically. MODEL 35135 AUDIBLE CONTINUITY TESTER The model 35135 is an audible version of the model Description 35100 Circuitracer designed for measuring continuity. The 35135 emits a strong (70db at 20cm) audible signal MODEL 35100 VOLTAGE AND CONTINUITY TESTER 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 35135s technical drawing. The model 35100 Circuitracer is a three-in-one test Assembly lab. The Circuitracer comes with the standard one inch probe tip and three feet of lead wire terminated by an ASSEMBLY OF MODEL 35100 FOR TESTING insulated ground clip. The 35100 will also use any probe UNPOWERED CIRCUITS tip with a 10-32 thread. The model 35100 tester includes When assembled with two AAA batteries in the handle, a low voltage lamp for measuring 1-3 volt powered the model 35100 circuitracer will become a self powered circuits and a neon cartridge for measuring 60-600 volt continuity tester, able to measure continuity between powered circuits. Batteries for measuring continuity from 0-10 ohms. 0-10 ohms are not included. The probe voltage on the Continuity tester assembly. model 35100 is 3V at 270mA maximum. For detailed specitications, please see 35100s 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. MODEL 35130 CONTINUITY TESTER 3. Turn handle on wire so that wire will retract to bottom The 35130 Circuitracer is the continuity only version of handle and insert two AAA batteries in handle. of the model 35130. The 35130 can measure continuity 4. Screw probe window onto handle. Touch clip to probe from 0-10 ohms. The model 35130 comes equipped with end to be sure Circuitracer is working properly. 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.
