Best multimeter
Well, got what I paid for... I bought a Chinese $30 multi meter and a $45 clamp meter several years ago.the clamp meter worked 3 times! But I haven’t needed one til now. I dropped the multimeter yeste...

When I am pre-sorting resisance or voltage for power supplies "almost" doesn't cut it. You didn't ruffle any feathers, and I had hoped that I made it clear that seeking accuracy was my own personal objective - solely. You are quite correct about resolution versus comprehensibility by the user. I choose 5.0 digit meters for my customers. Then black out the least significant digit with an ultra-heavy duty marker whose medium actually melts the tint into the meter's plastic lens.
The value of hundredths?
If the voltage is creeping up in the hundredths scale, there is no guarantee it will not impact the tenths to as much as 1 or 2 tenths. Yes a person can stand by a meter for 15 minutes to hope the tenths will not trip, but by seeing the hundredths ascend (or not), there is no guesswork. And if the voltage is hunting, a person had better be interested in finding out why.
A meter that reads 13.96 volts rather than 14.2 is intrinsically tricky.
If a person should reverse engineer some of these cheapo panel meters, they should find the same thing as I did, the comparator circuits are a world different between garden variety 2-1/2 - 3-3/4 digit meters and the 5.0 digit.
RC racers are demanding LSD accuracy much greater than what the general market demands.
People with batteries can have at their fingertips a qualifier for voltage that costs disproportionately to its accuracy. I choose to use these meters for my power supply products because they simply do not cost but pennies more than lesser meters. And Magic Marker scrawls are worth a small fraction of a cent.
I have a 3-1/2 lb box of bad NEW meters that can your's for the asking. Simply pay postage :)
An aside: Late 1960's...
"Say, did you know your speedometer reads seven miles per hour slow?"
"Does not"
"I checked it against the 4 mile-markers last week and a mile takes a hair under 53 seconds" I didn't continue that his 20 mpg mileage did not work for me -- I got 14.
Several miles later, a siren. A half-hour on the shoulder, and a scowling acquaintance got in and slammed the door.
It turned out it was all my fault because I had brought up the subject. We continued on in silence.
Any argument should be taken up with the battery. I'm easy going -- it isn't...
