Buying advice

When choosing a clamp meter, consider your typical current range, required safety rating (CAT III/IV for mains work), and whether you need true-RMS for non-linear loads. For professional use, invest in Fluke or Klein; for occasional DIY, cheaper options like Kaiweets suffice. Always verify the product's category as 'Test, Measure & Inspect' to avoid multimeters mislabeled as clamp meters.
