If you can afford a clamp-on ammeter, though... they are really, REALLY useful tools.

Make sure the one you get measures DC amps. We found a nice one for less than $100 that has two ranges for DC Amps... 4A and 80A. It is PERFECT for FRC work. We use it many times each year and it has got rid of a lot of "guess work" for us.

Please provide brand and model number? Available at Home Depot or Lowe's ? Or did you get it on-line ?

Thanks.

It is the JET 310021, as shown on page 112 of http://www.jetequipment.com/products...HT_109-113.pdf

I think we bought it at KMS Tools a few years ago... which doesn't do you a lot of good as far as a "lets just run out and get one" point of view*... but here is the closest thing they have to it http://www.kmstools.com/darson-instr...amp-meter-1868

I notice it says it is manufactured by "Darson" rather than JET and has a different part number, but it looks exactly the same and has similar specs.

I don't remember paying anything near that much for it, though... KMS Tools has awesome sales for a couple days every month, though, so it is possible that I could have picked it up at 50% off.

Hope you're able to find something useful in your price range... I'd recommend all my "local" sources... Lee's Electronics has one that costs less, but is less sensitive (http://www.leeselectronic.com/catalo...oducts_id=7847) and RP Electronics (http://www.rpelectronics.com/) has a selection, too... but the JET/Darson one is nice because of it's lower 4A/80A settings. These stores do sell on-line but maybe you can access similar stores nearer to home?

*after being sent out in search of various parts essential for the construction of the robot field that are only available at American Home Depots, or at non-existent chains like Lowes, or where the part number is different in Canada than the states, I know how this feels... believe me!

Hey thanks for taking the time to share all that. I've been meaning to pick up a clamp-on ammeter for years and it's about time I did something about it.
