Measure That Current!

Everyone who has anything to do with electronics has at least a multimeter at home and on the work table. But what about a clamp meter?

Here we examine the features of twenty clamp meters suitable for measuring AC and DC current, in price classes from a few dozen pounds to several hundred pounds.
