Menda Circuitracer Audible Continuity Tester – 0–50 Ohms, 35135

Quickly check electrical continuity, locate open circuits, and troubleshoot wiring with the Menda Circuitracer Audible Continuity Tester. Designed for electronics assembly, maintenance, and repair applications, this handheld tester provides an audible indication when a complete electrical path is detected.

The Circuitracer tests continuity over a 0–50 ohm range and produces a 2 kHz tone when the resistance between the probe and test lead is below 50 ohms. The audible signal measures approximately 70 dB at a distance of 20 cm, making it easy to recognize without looking away from the connection being tested.

Unlike continuity testers that rely on a light or digital display, the audible Circuitracer allows you to concentrate on probe placement while listening for confirmation. This is especially convenient when checking multiple connections, working in confined areas, or testing closely spaced electronic components.

The tester features a black butyrate plastic body, replaceable probe tip, and flexible test lead with a molded banana plug and removable alligator clip. The banana plug provides additional connection flexibility by accepting compatible accessories or connecting directly to a suitable banana jack.

Powered by two included AAA batteries, the Circuitracer is ready for continuity testing in unpowered circuits. Its compact handheld design makes it a useful addition to electronics repair benches, maintenance departments, and field service toolkits.

Made in the USA, the Menda Circuitracer offers a convenient solution for routine electrical continuity checks.

Audible Continuity Testing

The Circuitracer produces a 2 kHz tone when the resistance between the probe and lead connection is below 50 ohms.

This provides a quick way to determine whether an electrical path is complete without reading a display.

The audible indication is particularly useful when checking multiple points in a circuit or working in areas where visual indicators may be difficult to see.

For applications requiring exact resistance measurements, use an appropriately rated multimeter.

Keep Your Eyes on the Test Point

When troubleshooting closely spaced components, accurate probe placement is important.

The audible Circuitracer allows you to listen for the continuity signal while concentrating on the electrical connection being tested.

This reduces the need to look away from the workpiece and makes repetitive continuity checks more convenient.

The audible design is especially useful in brightly lit environments where a small indicator lamp may be harder to see.

0–50 Ohm Testing Range

The Circuitracer is designed to indicate continuity in circuits with resistance below 50 ohms.

This range makes it useful for checking wiring, connectors, switches, and other suitable low-resistance electrical paths.

It can also help identify broken connections and unintended conductive paths during troubleshooting.

The tester provides an audible indication rather than a numerical resistance measurement.

Flexible Test Lead with Two Connection Options

The 42" test lead features a high-flex stranded copper conductor with black PVC insulation.

A molded banana plug allows the lead to connect directly to compatible banana jacks or accept suitable banana-plug accessories.

The included alligator clip provides a convenient attachment for wires, terminals, and other appropriate connection points.

These connection options make the Circuitracer adaptable to different testing setups.

Replaceable Probe Tip

The tester features a replaceable probe tip with a 10-32 threaded connection.

The probe socket accepts compatible tips with the same thread specification.

This allows technicians to replace worn tips or select an appropriate compatible tip for particular testing applications.

Battery-Powered Operation

The Circuitracer operates using two AAA batteries, which are included.

The internal power source allows continuity testing without applying external power to the circuit being checked.

The probe operates at a maximum of 3V DC with a specified current of 15 mA.

Always disconnect circuit power and discharge stored energy before testing. Verify that sensitive components can tolerate the tester's applied voltage and current.

Durable Handheld Construction

The Circuitracer features a black butyrate plastic housing designed for convenient handheld use.

Strain relief at the test lead entry point helps reduce stress on the cable during routine handling.

Its compact probe-style design makes it convenient to carry between workstations or keep with other electronics troubleshooting tools.
