greets all,
don't know if i'm in the right group.
thought i purchased a 120/220V oscilloscope
(Tenma)
blindly plugged it into a 220V line and
it made a heartwrenching sound.

greets all.
new here.. i apologize if i'm in the wrong
forum. but i was hoping someone could help.

I'm new here, looking for a few pointers.
am getting into some basic vibration measurement
and purchased an accelerometer (10mV/g) and a

my accelerometer is mounted on a electric vibrator
whose frequency i control via an inverter (0-150Hz;
0-9000 rpm)...
