Trigger modes :
Pressing the trigger button repeatedly will
cause the trigger mode to switch between:
"norm"= Normal trigger: a triggering (or ma-
nual trigger) must occur before the sample
memory is filled. Use this mode when you
want to start displaying the signal when it
reaches a preset threshold value. (Fig 54)
"run"= Auto-trigger mode, the scope automa-
tically triggers if no triggering occurs for a fixed

period of time. This position is used most
frequently and should always be used for
measuring DC voltages. (Fig 55)
"once"= Sampling starts after triggering, comple-
tion will be shown by means of a check mark (1).
Triggering can be restarted by pressing the
'manual/restart' button. Use this mode to detect e.g.
a short glitch. (Fig 56)
"roll"= Roll-mode is available for timebases
of 10s/div or slower. Sampling is continuous
and the screen starts rolling as soon as it is
full. Use this position for "recording" slow
moving dc signals. (Fig 57)
