Some of their handheld DVMs are over $400.
I paid $275 for an original crispy flavor(*) Fluke 87 in about 1989.
Sometimes I also question their design decisions. I have the Fluke 8845A bench meter. It puts out around 10V (!) in the ohms ranges. That will
easily blow reverse Vbe of a modern RF transistor which is often 2-3V
abs max. Some might just zener and still kind of work but their noise
figure and possibly hfe might then be shot. The old annealing trick by crunching a burning cigarette butt on top of the transistor won't work
well anymore since they are flea-sized plastic packages, and almost
nobody smokes anymore.
My cheapo Harborfreight meter applies less than 300mV. So right now on
an RF board I am using a $5 meter because the $1000+ meter isn't up to
the job.
At the very least I'd have expected Fluke to provide aselectable lower voltage while sacrificing accuracy. Being off by 0.1% in the ohms range
sure beats blowing an unobtanium RF part.

Some of their handheld DVMs are over $400.
I paid $275 for an original crispy flavor(*) Fluke 87 in about 1989.
I should add that I'm very fond of these DMM probes:

I was just probing a very tight board with a sewing needle.

Imagine cutting the needle in two, splinting it back together but
bridging the gap with a 950 ohm 0603 resistor, and soldering a coax
center to the top end. You now have a tiny many-GHz 10:1 probe.
At most signal levels, such probes don't need a ground.

At decent signal levels probes do not need to connect either...

At most signal levels, such probes don't need a ground.
At decent signal levels probes do not need to connect either...
DC coupling and amplitude calibration are sometimes nice.
I've been toying with going into the probe business, fast stuff, passive resistive and active fet or equivalent. It wouldn't be hard.
