Oscilloscope help

[oscllitr]

Hello,

Wondering if someone can help me figure out whats going on. I new to
oscilloscopes, and wonder if something is wrong with my scope, or if
its user error.

When I connect the scope to its internal calibrator, the square wave
drifts back and forth, left to right.

Thanks

Set the trigger to "normal" instead of "auto" and then adjust the
trigger level knob.

Thanks for the reply. I will give that a try.
