On thread 60851 recently, there was a discussion about Clamp Meters. As a result of this, Mike Harding and I both ordered this clamp meter on e-Bay. Seemed an excellent price and good specs.

Well, mine has arrived. I've only given it a brief test, but it seems to work very well. Came with batteries included and a handy little carry case. If it holds up, it is just what I was after. Combined multi meter and clamp meter; quite small and very cheap.

Have you got yours Mike? Any report?

Both zacc. The clamp meter part lets you measure current flow without breaking the circuit. Just put the 'clamp' over the wire and it measure the current flowing through it. AC clamp meters are quite cheap. DC ones (what we need) have been quite expensive. Until recently, hundreds of $. Available more recently at around $150, but the one I bought was by far the cheapest I've seen.

The multi meter part is your basic AC /CD multimeter. Very handy and necessary, but easy to buy at around $20 to $30 - even cheaper for the cheapies.

Put the two together at a good price and you have a very handy bit of kit that we can all afford.

Look closely to ensure what you are looking at is a DC clamp meter. As I said above, AC ones are cheap. DC ones have (until recently) been expensive.

Get off your lazy arse Harding and give us a technical analysis.

FFS, is it any good?

Yes :)

Well worth the cash. I'll do a proper test on it tomorrow but some quick tests I did last week indicate that for DC current measurement below about 3 amps it's not very accurate (10% ish - something to do with the Hall Effect measuring technique, I think) but over that level it improves a lot and is more than adequate for non lab work.

The other functions (volts, ohms etc) all seemed as accurate as any $50 meter ie. pretty good.

Does it have a peak hold function? I have an electric start 18hp Briggs and Stratton motor, and have wondered what maximum current the starter motor uses.

Hey Norm,

Looks like a handy unit. Just one question regarding the accuracy after reading it's specs on ebay.

For it's DC current accuracy it says best accuracy of '±(2%+3)'. Am I reading this right in that say my fridge with an approximate draw of 5amps, its accuracy will be ±(0.1+3), ie 3.1amps. That doesn't sound too accurate. I think I might be reading it incorrectly. Hopefully am cause I want one too!

Cheers,
Paul.
