I got a BK 2120B from a friend. It seems to be in almost new condition.
Anyway....
I have it hooked up to the 120 wall supply. The scope ground is on the power cord ground, the probe is on the hot lead, and the neutral is safed off.
I have never used a scope before, and the manual is a bit confusing for me. I understand the Volts/Div. knob, but I am confused by the pullout knob in the center of that V/D knob. It is marked "pull x5 mag". I guess it increases the V/D by 5 times, but it is also variable. So, for example, you can be looking at a peak to peak wave of 100 volts, turn that center knob, and increase or decrease the number of divisions. How am I supposed to use that knob exactly.?
Thank You
