Any advice on DC capable amp clamps out there for around $150.00 for general automotive and around the house. Looked at Craftsman professional, Extech, and of course Fluke. I don't really want to spend the $300 for the fluke, but will if all the others have a bad reputation.

Quite a few are AC only.

Unless you are able to make serious/frequent use out of it to make your money's worth (then go with fluke), otherwise, go with whatever's the cheepest (IMHO). I have all kinds of multimeters and the cheepest analogue meter is the one I used the most (sino-made, a Shamwa 360 clone) is the cheepest of all; keep my fluke and HP/Agilent indoors. Q.

any reason why you use an analog? I do the same thing with my outdoor use cen-tech.

Analogue multimeters are best suited for testing that fluctuates quite a bit, in either DC , AC or current measurements. My weary eyes are more adopted to reading analogue meter needle deflections than jumpy numerics on DVM. Q.

I bought an earlier version of this model from ESI: http://www.esitest.com/687.html Look on Amazon for a lower price. If you just want the clamp for use with a DMM then they sell that for a little less (ESI 695). The version I bought allowed external probes and was a DMM as well, but the basic accuracy, though fine, was lower than a Fluke. Looks like ESI dropped my model. A negative battery cable fits very well in the jaws. I used mine to diagnose a generator on an old Buick.

This is not an easy task to ask a meter to to. Even if it gives a reading, the meter is probably not fast enough to catch the true readings. That is why there are scopes with clamp on probes. The current draw of a starter will fluctuate as the engine is being turned over, especially if there are some bad cylinders with low compression (less current draw).

I got a Craftsman Model# 82369 a few months ago for under 50$. AC/DC clamp on ammeter. Now about 54$ Seems pretty accurate according to my shunted meter, just use alkaline batteries in it, not rechargeables.

I have a similar Sperry model. It has data hold which I find useless. You have to press a button when you want to freeze what is on the screen. It is not a "max" hold.
