It looks also complicated, and if i take a look at the youtube movie, i would have short circuit with a 2 ohm resistor.
No i just want to measure ohms not volts, else they should have build that into the multimeter.

For now i have my sets of 17 resistors, a whole lot, need to solder those first,
by the time i need to measure more resistors i expect a aneng meter with 5 digits for 10 euro shipped on ebay.

The 17 resistors are for a voltage controlled oscillator digital to analog converter.
Every synthesizer voice needs 17 resistors, here i made a new topic about the resistors what i dont understand :

It's very old-school construction inside - surface mount but not much integration - lots of 74XX logic and stuff.


Doesn't make it worth any less though,  I say there's no better time to buy one!

The Hioki DT4282 is very, very fast, it leaves my Keysight U1282a in the dust in terms of measurement speed and autoranging.

It's also 0.03% accurate on the Ohms range and measures up to 600MOhm. I don't think there's a handheld DMM that can beat those specs.

When measuring capacity ?, are there also small values ?

Specs are here:

https://www.hioki.com/file/cmw/hdInstructionManual/93344/pdf/?action=browser

The lowest range is 1.0nF with 1100 counts at 1%+/- 20 so that's around 1pF resolution.

(ie. it beats the Fluke 87V and Brymen 869S here as well :popcorn:)

That is really a nice meter,

Customs duty is negligible, and VAT won't change. Just import it.
