My experience is that there are true RMS clamp meters that measure current via max/peak method and newer meters that use the in-rush method (ie, Fluke330 series). Accurate measurement of in-rush current has alway been possible since the advent of true RMS meters with Max feature. Fluke is now touting the triggered 100mS inrush measurement feature as the new "must-have" thing. How much more useful than a good true RMS clamp meter with max/hold is a triggered 100mS meter? For measurement of synchronous motor currents (with and without adjustable speed drives (ASDs)), is a trigger or a fast measurement really necessary? Helpful? A waste?What do you think?

Is there something you need to do that the meter you already have is not adequate for? If what you have works, then there's no reason to upgrade.

Do I need a new Fluke clamp meter?

Ahh... I'd not seen that.

Maybe means "Ignorant, Irrelevant, Vacuous"

One \'I\' is to the right of one, so they add to \'2\', but that sum is still smaller \'V\', and on its left, so it\'s subtracted, with the difference being \'3\'. That\'s why it\'s cutesy and dumb-ass. JF

That P is so third rate that 'e can't form a proper roman numeral.
