Menda Circuitracer 3-in-1 Voltage & Continuity Tester – 35100
Locate electrical continuity, identify open circuits, and check for voltage with the Menda Circuitracer 3-in-1 Voltage and Continuity Tester. Designed for electronics technicians, maintenance personnel, and electrical troubleshooting applications, this compact probe-style tester combines multiple testing functions in one convenient handheld tool.
The Circuitracer features an illuminated probe tip that provides a visible indication directly at the point of contact. This allows you to concentrate on the connection being tested instead of repeatedly looking away at a separate meter display.
Three operating modes make the tester useful for a variety of troubleshooting tasks. With two AAA batteries installed, it checks continuity in unpowered circuits over a 0–10 ohm range. For powered circuits, it uses an incandescent lamp for low-voltage testing and a neon cartridge for higher-voltage testing.
The tester includes a standard 1" probe tip and a 3-foot lead wire terminated with an insulated clip. Its probe accepts compatible replacement tips with a 10-32 thread, providing additional flexibility for different testing applications.
Made in the USA, the Menda Circuitracer is a practical supplemental troubleshooting tool for electronics assembly, maintenance, service, and fieldwork.

Three Testing Functions in One Tool
The Circuitracer combines three useful electrical testing functions.
Continuity Testing – Unpowered Circuits
With two AAA batteries installed and the appropriate lamp configuration, the tester checks continuity in circuits with resistance in the 0–10 ohm range.
This mode is useful for checking wiring connections, identifying open circuits, and verifying electrical paths when power has been disconnected.
Low-Voltage Testing – Powered Circuits
The incandescent lamp provides a visual indication when testing suitable low-voltage powered circuits.
This mode operates without batteries. Menda's technical bulletin specifically describes testing 1–3V powered circuits, while the Micro-Tools listing specifies a broader 0–60V AC/DC mode. Refer to the manufacturer's technical documentation for the correct configuration and applicable operating limits.
Higher-Voltage Testing – Powered Circuits
The neon cartridge provides an illuminated indication when testing powered circuits in the specified 60–600V AC/DC range.
This mode does not require batteries.
Always use the correct lamp configuration and follow the manufacturer's operating instructions and applicable electrical safety procedures.
Illuminated Probe Tip for Convenient Troubleshooting
One of the Circuitracer's distinguishing features is its lighted probe tip.
Rather than requiring you to look away from the test point to check a meter display, the illuminated indicator is positioned close to the electrical contact.
This design is particularly convenient when checking multiple connections or working on closely spaced electronic components.
The visible indication helps technicians maintain attention on probe placement during testing.
Continuity Testing Without External Circuit Power
The continuity function operates using two AAA batteries installed in the tester.
This allows the Circuitracer to check for a complete electrical path in an unpowered circuit.
The specified continuity range is 0–10 ohms, making it useful for identifying basic connection faults, broken conductors, and open circuits.
Always disconnect circuit power and discharge stored energy before using continuity mode.
Voltage Testing with Interchangeable Lamps
The Circuitracer uses different lamp components for its voltage-testing functions.
The incandescent lamp is used for low-voltage applications, while the neon cartridge is used for higher-voltage detection.
Both voltage-testing configurations operate without batteries.
The illuminated indicator provides a straightforward visual response when the appropriate voltage is present.
This tester is intended for voltage indication rather than precise numerical voltage measurement.
3-Foot Lead with Insulated Clip
The tester includes a 3-foot lead wire terminated with an insulated clip.
This allows one connection to remain attached while the probe is positioned at different test points.
The lead length provides convenient reach for electronics troubleshooting, assembly work, and general service applications.
Replaceable Probe Tip Design
The Circuitracer includes a standard 1" probe tip and accepts compatible replacement tips with a 10-32 thread.
This allows technicians to use an appropriate probe configuration for different testing situations.
The replaceable-tip design also provides flexibility when maintaining the tester.
