I once had
an argument with a fellow who didn't believe
potentiometric voltage measurement systems ever had any value, because
there have been "multimeters", VOMs and VTVMs for many decades. "Why
do all that comparison stuff with standard cells when you can just
MEASURE the damn thing?" he asked. He didn't understand that there's
a voltage reference of one sort or another inside every VOM and VTVM.
He obviously never had a lab course in electrical measurements. From my college experience, I grew to hate wall
galvanometers.
As a collector of physics and metrology antiques, I seek out wall
galvanometers! :)
I regularly perform measurements with them, for no other reason than
"because I can". I find them a pleasure to use.
I do prefer the HP 3458A, though.
That
summer, I wound up on a job that required me to haul around a
portable potentiometer doing endless calibrations...
