Recording times (reference value) for a Z4001 SD Memory Card 2 GB
(Repeat Record: 1 week, Repeat Number: 55 times)
• Figures indicate the amount of recording time after the SD memory card has been initialized.
• Recording times do not account for event data and screen copy data. Recording times may be short-
ened when event data and screen copy data are stored on the card.
• Recording times are not dependent on connections.
• When repeated recording is set to [O
FF], the maximum recording time is 35 days.
• When repeated recording is set to [
1 Day], the maximum recording time is 366 days.
• When repeated recording is set to [
1 Week], the maximum recording time is 55 weeks.
• Harmonics order data is not saved for [Power], but
it is saved in THD.
Outputs the display image to the SD
memory card at the
