• UpdatingoftheWaveform
On the screen, 30 dots along the time axis is represented by a unit called division (see
the figure on the previous page). The displayed waveform is updated at an interval
corresponding to one dot. This interval is determined by the time corresponding to one
division (referred to as the trend interval). The relationship between the trend interval
and the speed of movement of waveforms on the screen is as follows:

*1 40 dots per division. Selectable on the DX2004 and DX2008 (release number 3 or later).
*2 Selectable on the DX2010, DX2020, DX2030, DX2040, and DX2048 when the scan interval
is set to fast sampling mode (release number 3 or later).
 SwitchingtheTrendInterval
You can switch from the normal trend interval to the secondary trend interval during
memory sampling and vice versa. For the operating procedure, see section 5.3.
