Fluke 302+ Digital Clamp Meter, 30 mm Jaw, 400 A AC Current, 600 V AC/DC

With a 30 mm jaw, the Fluke 302+ Digital Clamp Meter can take AC current readings on larger conductors. Its compact format makes it practical to carry in a work bag for everyday electrical troubleshooting.

It measures AC current up to 400 A and AC/DC voltage up to 600 V. Resistance and continuity functions add useful checks for diagnosing electrical issues.

A backlit display helps keep readings visible in dim work areas. What can you check with one compact meter? The 302+ brings several common troubleshooting measurements together, along with a jaw designed to accommodate larger conductors.

Pros

The clamp design provides a way to measure AC current without relying on probe contact for that reading. Its 400 A AC current range supports everyday maintenance tasks, while the 30 mm jaw makes it useful when working with larger conductors. For voltage checks, it measures both AC and DC up to 600 V.

Resistance and continuity measurements add practical options when investigating electrical issues. The large, backlit display is designed to make readings easier to see across different lighting conditions. Its CAT IV 300 V/CAT III 600 V safety rating is relevant when selecting a meter for electrical testing, match the rating to the application and follow appropriate safe-work practices.

Highlights

The 302+ combines clamp-based AC current measurement with test-lead measurements in one digital meter. The included Fluke TL75 Hard Point Test Lead Set supports general-purpose testing, with a test lead and probe combined in one unit. This setup gives technicians a choice of measurement approach: use the jaw for AC current on a conductor, or the leads for voltage, resistance, and continuity checks.

Buyers often describe the meter as easy to use and reliable, while feedback on accuracy is mixed. These impressions can help set expectations, but the meter’s stated measurement ranges and safety rating are the more useful points to compare when choosing equipment for a particular task.

Who it’s for

This meter suits routine electrical maintenance and first-pass troubleshooting where AC current, AC/DC voltage, resistance, or continuity readings are needed. It is a practical alternative to a probe-only approach when measuring AC current on conductors that fit within its 30 mm jaw. For a typical check, a technician can use the clamp for current and switch to the TL75 leads for a voltage or continuity measurement, with the backlight supporting work in dimmer spaces.

Practical questions

What measurements does the Fluke 302+ provide? It measures AC current up to 400 A and AC/DC voltage up to 600 V. It also offers DC millivolt, resistance, and continuity measurements.

What is included with the meter? The listed package includes the 302+ clamp meter, a Fluke TL75 Hard Point Test Lead Set, two AA batteries, and a two-year manufacturer warranty.

What does the 30 mm jaw do? It provides room to take AC current measurements on larger conductors that fit within the jaw. The meter’s separate test leads are used for measurements such as voltage and continuity.

Is it worth it?

The Fluke 302+ is a focused choice for users who want a portable clamp meter for everyday electrical checks rather than a probe-only meter. Its 400 A AC current capacity, 30 mm jaw, AC/DC voltage measurement, resistance and continuity functions, backlit display, and included TL75 leads make it well suited to routine troubleshooting and maintenance tasks.
