Do I need a new Fluke clamp meter?
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, Fluke 330 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? |
