This meter has come in handy for SO many things especially for measuring DC current in the motorhome. I can instantly know that my solar system is pumping out what it should be without removing any wiring (just place the clamp on the wire).

And it includes all the usual metering. Perfect for what I'm using it for!

5.0 out of 5 stars Best Low Amperage Clamp you will ever buy, March 7, 2009

This review is from: Sheffield Research/GTC CM100 AC/DC Amp Clamp Digital Meter - 100 Amps (Misc.)

This is the best amp clamp I have ever used and well worth the money. I use this clamp at work to find amperage draws on luxury cars and its very accurate. You can find the same amp clamp(cm100) by name brand manufacturers for twice the price. I definitely recommend this low amperage clamp for anyone who has to find a amperage draw.
