Thinking of getting a clamp ammeter

[tom66]

I am looking for a clamp ammeter.

I would like to use it for debugging and profiling power supplies as I have had a few troublesome TVs where it could have been quite useful (can see if PSU is attempting to start up, for example.)

My ideal device would be:
- Capable of measuring AC & DC current
- Capable of up to 20A current (more is good, but I don't tend to use much that much more...)
- True rms for typical full-wave rectifier input current measurement - good crest factor

If possible:
- Output for the current signal from the probe to plug into a scope - I can potentially measure power factor and line noise with this
- Built in second multimeter could be useful

This Uni-T looks good, but it doesn't have the scope output (which would be very useful for me): http://www.ebay.co.uk/itm/Brand-New-...ht_1348wt_1189

I suppose I could get a separate hall probe for my scope but those are pricey plus I would loose the ability to make simple rms current measurements without the big scope with built in rms digital measurement (which stays upstairs mostly...)

I wish I knew more about clamp meters to offer some feedback, but unfortunately I don't.

PS. I see you added the don't PM me for help in your sig file. That is a good sign of the respect you have earned from others.

Yes, I get a lot of PMs from help. Mostly people asking about TVs I've never heard about. I do not know everything about TVs!
