 Never known of a clamp style dc amp meter. Check dc amperage by running through meter leads. Am i wrong?
- boogie_4wheelExplorerI have an Extech clamp meter that will do dc on the clamp, and will measure peak inrush current.
 I don't have it in front of me or I'd list the model.

 Boon Docker, have you personally used the meter your post linked?
 Also see 3 DC clamp meter at Harbor Freight but not sure of the wuality.
 Thanks
 Yes I own that one, it is a well built, accurate meter for the price.

 Several people like the Craftsman clamp meter which sells for about $60.

 The Harbor Freight clamp meters do not measure DC amps. Most cheap clamp meters do not have a DC amp range so check carefully.
 I have an older Tenma clamp meter that works well.
 I was going to grab my meter and post the model number but I see that TOM beat me to it.. Thanks Tom.. oh and I second your suggestion.
 This is the one I have, ordered on line on sale for store pick up. Temp probe doesn't work but not something I need.
- landyacht318ExplorerThe sears meter is not true rms, or if it is they do not think it a feature worthy of advertising.
 It does not measure inrush peak amps.
 It reads out of whack with Nimh aaa batteries I for get if it is high or low, use alkaline AAA instead.
 I recently replaced the alkalines with duracell lithium aaa and the amperage readings seem to be higher than before, by 2 amps at 40.
 The lithium AAA seem to have higher resting voltage or do not drop as low under load, or something, but I am less confident in my clamp Meter's reading than before with normal alkaline AAA.
- MEXICOWANDERERExplorerUni T, is exactly like the one I have. Hahahahahaha it is more accurate than the hundred dollar Triplett that ended up Seppuku after a hurricane. I use a 4 terminal 5-1/2 digit Kelvin meter and a Manganin shunt to qualify my ampere meters. They all come from the land of the Great Wall (even Fluke?).

 Clamp-on usually goes 200+ amps. And no need to disconnect a wire.

I just wanted something that would measure DC amperage and didn't cost an arm and a leg. This fills the bill. The only real issue is the fact that when you're using it your hand tends to cover up the display.

 Fluke inexpensive GULP
