Appendix 2.3 Timebase and Maximum Recordable
Time
Recordable time can be verified on the Status
Settings screen.
These tables show cases in which minimum- an
d
maximum-capacity memory boards are installed.
Recordable Time = Timebase × Recording Length
• Setting a slow timebase may result in a very long recording time (over a year) which ma
y
exceed the guarantee period or product life, in which case we cannot guarantee operation.
• The maximum recording length depends on the number of channels used.
Refer to "Appendix 2.4 Memory Capacity and Maximum Recording Length" (⇒ p. A37).
