Level trigger:
Triggering occurs when the signal rises or falls
through a specified voltage level.
Window trigger:
Triggering occurs when the signal level rises
above or falls below specified upper and lower limits.
Voltage drop trigger:
Intended particularly for 50/60 Hz
commercial power, triggering occurs when the peak voltage is
below the specified value.

Maximum Recording Time for the Memory Function
• Because data is not recorded directly to the CF card, maximum recording time is independent of CF card capacity.
Maximum recording time is determined only by internal memory capacity.
• Operation cannot be guaranteed when recording continuously for more than one year (with a slow timebase).
• Maximum recording length is the same whether using one or two channels.
