Welcome to CuVoodoo,
the sorcery of copper.
actually more like 4 years
the most common voltages
with ground I meant earth connection
again, I meant earth
100W as written there, not 80W
"Conformité Européenne" vs "China Export"
not the one which is set
the first digit after the point
the value before the point
I wanted to short the power supply, not the multimeter. But the result is the same.
what is generated by the power supply
you can also get it on my git
actually the checksum is a simple addition of the previous bytes, thus it can not detect if a 0 is missing
on UART it idles high, not RS232
for this multimeter
UT-D02 and UT-D04
we also see this noise when not connected ...
<0.20%
that's probably even mandatory
probably used to measure the current
