Horizontal Axis
◄POSITION► Knob
Use this knob to move the trigger position. When you move the trigger position, the ratio of the
displayed data before the trigger point (the pre-trigger section) and the data after the trigger point (the
post-trigger point) changes. This knob has a push switch. You can press the knob to reset the trigger
position to 50%.
DELAY Key
When you press the DELAY key, the key illuminates. Then you can set the trigger delay using the ◄
POSITION► knob.
You can reset the trigger delay to its default value (0 s) by pressing the ◄POSITION► knob when the
DELAY key is illuminated.
TIME/DIV Knob
Use this knob to set the time-axis scale. If you change the scale while signal acquisition is stopped, the
waveform is expanded or reduced horizontally. If you restart signal acquisition, the DLM4000 acquires
signals using the new time-axis scale.
