Variable Input Sensitivity

The variable input sensitivity allows you to adjust any input
sensitivity continuously, for example to set the amplitude
of a reference signal to exactly 6 divisions.
The input sensitivity of a range can be increased up to 2.5
times, for example between 10 mV/div and 4 mV/div in the
10 mV/div range.
To use the variable input sensitivity on for example
input A, do the following:
1 Apply the input signal.
2
Perform an Auto Set (AUTO must

appear at the top of the screen).

An Auto Set will turn off the variable input sensitivity. You
can now select the required input range. Keep in mind that
the sensitivity will increase when you start adjusting the
variable sensitivity (the displayed waveform amplitude will
increase).
