Almost forgot, make sure you get "True RMS" capability on both the
multimeter and the clamp meter. If you don't have True RMS, your AC
measurements will not be accurate on non-sinusoidal waveforms.

I wish I could say the same.  My Fluke died. The LCD display disappeared.

Yeah, I left my old one out in the sun and the display overheated. $0
and 5 minutes to swap the display and it was as good as new, and still
working almost 3 decades later.

It's been a while since I owned a Fluke, but I thought they were
overrated and died more often than the cheap meters. I was in the repair
business for years and was tougher on them than most. I've killed two
flukes as opposed to one of the other brands.

Almost all my measurements were DC, but you would want true RMS if you
are dealing with inverters. As far as accuracy on DC, even a $ digital
meter is very very accurate. We didn't have DC clamp meters, but that is
one cool idea!

   Also, I've always hated auto ranging meters, sluggish and annoying.

Take it back, they have a lifetime warranty.


I've had the complete opposite experience. In our production department
for example, we have kitted the operators out numerous times with cheap
meters, and not a single one of them has survived the oils, water,
drops onto concrete floors etc. Some of them only last a matter of
weeks before the cases crack, switches don't work etc. Not one single
Fluke 70 or 80 series has died, with the exception of the Fluke 19
series which was a trial run made in China with cheaper parts and case,
instead of made in the US. They quickly discontinued that model and
learned their lesson!


What the Fluke gives you over the cheap meters is "measurement
confidence". The Fluke is made with *much* higher quality stable
components, particually the thick film reference resistor network. This
means that you can be more confident the Fluke is giving you a correct
reading, throughout it's entire life, or calibration period, whichever
comes first ;->

Fluke don't give you a *lifetime* warranty for nothing.

I've opened dozens of meter brands, and the only one that came close to
the Fluke in build and component quality was Tektronix. Fluke now own
Tektronix meters.
The wavetek/metermans are decent quality, and I think they have been
bought out by Fluke too.
If you are going to buy a cheap Taiwanese meter, I'd suggest the
Brymen.


I don't agree. A good autoranging meter is quicker and much less hassle
than changing ranges.
But I can appreciate why some people like them, that is why most
autoranging metrs have a manual range override.
