i can measure over few 0hms even in specifications said can measure over 1 0hm i just have 0ohm and wiht my old tester i can measure over 7,3 0hm its on shunt resistor for an ina219 breakboard. i whant to know ir are correct i can't measure suchs devices.

Resistance: 100m to 1M Ohm, ±1%, 3M Ohm ±5%

thank

  Hello A.R,

  I'm not particularly familiar with the ina219  but the shunt resistor on the board appears to be 0.1Ohms.

  With your Owon multimeter it seems to be measuring incorrectly at ~2Ohms, this is likely due to resistance in your leads, what measurement do you get if you short the leads together?

  The Pokit Pro seems to be measuring it correctly to within its spec of 1% +-3 Readings in this case would be 0.0-0.4Ohms (as the Pokit Pro cant measure below 0 ohms).
