Brand new piece of test equipment!

So accuracy has improved to 3 digits.

I can think of no situation where you would require any more than that anyway.

So you're saying you would never need more than three digits?

Thanks !
Curious that the range is written 10V for example and you can mesure up to 19.9V. Why not write 20V for range

Two and a half, as I said.

(And to be pedantic, that is precision, not accuracy.)

Nope, it's resolution.

Precision would determine how well it can reproduce the result when given the same conditions.
Accuracy tells us how close that measurement is to the actual value.

Cool and recently wondered whether there were 2 1/2 digit multimeters while watching this video, since all I could see were 3 1/2 digit:

Precision =/ Accuracy

3.14 Accurate, but not precise
3.887897894536748645 Precise, but not accurate
3.141592653589793238 Accurate, and precise

No.

A better explanation is this;

you have a battery, across it is a 1meg resistor, the battery was charged to a perfect 5v at the beginning of each meter connection
you connect your multimeter
you read 5 measurements, these are your readings;
5.0003
4.9997
5.0004
4.9996
5.0000

you connect another meter
you read 5 measurements, these are your readings;
5.0014
5.0014
5.0012
5.0012
5.0013

you connect another meter
you read 5 measurements, these are your readings
5.00315
5.00312
5.00313
5.00310
5.00308

you connect another meter
you read 5 measurements, these are your readings
5.00029
5.00014
5.00003
5.00013
4.99985

you connect another meter
you read 5 measurements, these are your readings
5.00000
4.99999
4.99998
4.99997
4.99996

The first meter is accurate, its readings are closer to the real value, so averaging will give you a closer value to the real value.
The second meter is precise, its readings are relatively close to each other, meaning it will give you repeatable results, its error can be "calibrated" to give you a value closer to the real value.
The third meter is of higher resolution and precise, its readings are relatively close to each other, meaning it will give you repeatable results, it's extra resolution makes it easier to detect smaller changes in value, its error can be "calibrated" to give you a value closer to the real value.
The fourth meter is of higher resolution and accurate, its readings are closer to the real value, so averaging will give you a closer value to the real value, it's extra resolution makes it easier to detect smaller changes in value.
The final meter is of higher resolution, accurate, and precise, its readings are very close to the actual value, they are repeatable, and it's extra resolution makes it easier to detect smaller changes in value.

Did u snag that off of eBay? I have been watching obe on there and haven't made the move to buy it. Awesome score!

my latest nixie purchase:



top counter just arrived today.  has 1 bad digit (bad 8 on one of the tubes) but otherwise all working.

(bottom 2 boxes were also recent purchases; I've been doing some home lab upgrades lately)

love the blue vfd, but also have a liking to old style nixies.

You bastard!  I love it,
