«s (60 mV + probe attenuation factor p-p).
If DC coupling is used, the DC offset voltage must meet the
following criteria:
at a VOLTS/DIV setting which gives a p-p signal > 4 divisions,
the peak signal + offset must be =£ 12 divisions.

Volts measurements depend on peak signal measurements.
Noise on the input signal, even if at a low repetition rate that
makes it difficult to see, will be detected and will affect the
measurements.
