Do I need a new Fluke clamp meter?

Bob E. 16 years ago

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?

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.

"Need" is a subjective term.

If what you want is to make a repetitive job easier, I would recommend (without personal experience) a good hand held oscilloscope such as Fluke makes. They are not cheap. With that, you need a current transformer with a load resistor called a Rogowski coil equivalent. That is the clamp-onm and sensing part of a clamp-on meter. Record the start-up current waveform. Then you have a record of the waveform you can data process to your heart's content instead of relying upon someone else's cryptic algorithm.

Read Fluke application note 1629920 and work it out.

At least I never get to see Proteus's posts, except as quotes. Google gets filtered out here. I pray that he'll never get a proper news service.

From Wikipedia: "Proteus is a bacterial genus within the medically important group of Enterobacteriaceae. Species most commonly associated with clinical disease are Proteus mirabilis, Proteus vulgaris and Proteus penneri. Proteus species are notorious in medical microbiological laboratories because of their rapid swarming growth on commonly used agar plates."

Since putting smaller Roman numerals to the left of larger ones means to subtract them from the larger, that\'s just a cutesy, dumb-ass way of writing "3". JF
