The display shows the square wave with 6 divisions vertical and just over

knob I can adjust the display to show exactly 10 divisions. When this is
done is the display correct? Or is it the calibration bar that is wrong?

Do me one favour:
Please don't connect your scope to the mains or then genset. It might
kill you, judging from the questions you ask here.

This bar is labeled as 300 mV 30mA ~1KHz.

This means "about". And you will get only about. Noone cares about the
frequency. The rect-wave is for calibrating the Vpp and the compensation
of the probe. Nothing more.


Thanks,

Greetings Nick,
Why might I be eletrocuted by plugging in the scope to the mains and
then touching the probe to the hot lead from the AC generator? If I'm
isolated from the power where does the danger come from? Look, I
respect electricity and am not going to touch any live wires. I
realize that 'scope case is grounded. I'm serious Nick. If I take the
proper precautions when working with lethal power what is the danger
that I'm not seeing?
Thanks,
Eric
