The Mini Clamp Multimeter function is amazing

Being able to measure current without actually having to disconnect wires or interrupt a circuit is huge. I’ve used larger clamp meters in the past, but they were kind of a pain to maneuver in tight spaces, and they were pretty heavy. This one’s clamp is easy to open wide enough to fit around cables, but still small enough to get into those tighter spots where bigger tools just wouldn’t fit. It’s perfect for testing electrical systems in cars or small appliances.
