Hey, how does the 500000 count work with the accuracy and voltage ranges ?
The specs say "DC voltage measuring range - 0,01m...500m/5/50/500/1000V" and "DC voltage measuring accuracy - ±(0,02% + 2 digits)"
For example, if I measure a LiPo cell that is exactly 4.2 volts, what does the meter say ?
This is how I see it, but I'm not that sure myself:
Voltage is under 5V, so I get "4.<decimals>".
Accuracy is "±0.02%", so error there is 0.00084V.
The +2 counts means the last digit can be smaller or bigger by 2.
500000 count means the first number can be between 0 and 5 (maybe 0-4?), with total of 6 numbers on the screen.
So TL;DR:
On the BM869, would a spot on 4.2V measure as something between 4.20086 and 4,19914V ?
