Do I need a new Fluke clamp meter?
Bob E.
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.

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".

Only works for one 'I'.
John Fields

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.

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