Hi Measurement accuracy as stated in the listing is 0.3% or 3,000 ppm. Some listings call it out as 0.3% +/- 2 LSD. Since they removed the markings from some of the chips, figuring out exactly what’s in there could be a bit exciting.
Full scale is 33V so the full range display would be 33.000 . The LSD is 1 mv so +/- 2 LSD would be +/- 2 MV. We are looking for 5 / 2^16 volts. That’s 76 uV. Ten DAC LSB’s still don’t get you to 1 mv. I’d bet the target audience for these meters are some sort of 24V battery setup. The voltage range would make sense in that case.
