The Revolectrix Bump controller showed
2. 19 amps, while the two meters read
2. 19 and 2. 17. That’s certainly accurate
enough for our purposes.
The accuracy is certainly close enough. There is a .02-amp
difference in the readings. That could be attributed to
losses between the first connection point and the
available meters are accurate enough. If
you’re working in a laboratory, maybe
I recently heard from two readers who
did some nice side-by-side tests of clamp
meters that they bought on Amazon for
$36 and an extremely accurate Fluke
meter. They found that the meters
were within a few hundredths of each
other when measuring current. That’s
more than close enough for our use.
Don’t become wrapped up in worrying
about thousandths of a volt or amp.
We’re flying model airplanes, not space
We don’t need to be perfect, but we
do need to know what our setups are
doing. There is an abundance of gear
out there to help us with that and not
break the bank.
