What to know before buying

Listing details to confirm

The title identifies an AC/DC 600 A meter, while one feature bullet describes AC current only. The description mentions frequency and diode testing in addition to the listed functions, but the provided feature list does not confirm those two functions. Confirm the exact measurement capabilities and rating details for the selected listing before relying on them.

Customer feedback is broadly positive about compact size, functionality and perceived accuracy, which aligns with the stated slim jaw and multiple measurement functions. Those reports are customer perceptions, not independent verification of measurement accuracy. The aggregate ratings are favourable overall, but a smaller low-star share means experiences are not uniform.

Positive themes

Customers describe the meter as compact and appreciate its functionality.
Feedback describes readings as accurate.

Frequently asked questions

Does the Fluke 301D/ESP measure both AC and DC current?

The title and product details specify 600 A maximum for AC and DC current. One feature bullet describes AC current only, so verify the selected listing if the DC range is essential.

What other measurements are listed?

The feature list names voltage, resistance, continuity and capacitance. Frequency and diode testing appear in the product description but are not confirmed in that feature list.

Are batteries included?

The listing says two AAA batteries are required and included.
