s/div to 100 ms/div
User’s manual section 5.12, “Setting T/div”
The time axis setting is the setting for the amount of time per grid division. If you slow (increase the value of) the time
axis setting, the display is updated according to triggers, so the instrument changes from update mode to roll mode in
which the waveform scrolls from the right to left side of the screen. Roll mode is useful when you want to observe
signals with long periods or signals that change slowly.
