Characteristics selected with the [Recording Items] setting are all automatically saved to the SD memory
card in the binary format. Up to 100 measurement data files can be created on a single date.
Recording times for (reference value) a Z4001 SD Memory Card 2GB
(Repeat Record: 1 Week, Repeat Number: 55 times)
• 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 [OFF], the maximum recording time is 35 days.
• When repeated recording is set to [1 Day], the maximum recording time is 55 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.

Saving data
If an SD memory card is not inserted into the instrument, measurement data will not be
saved.
Save
procedure
1. Set the recorded items and TIMEPLOT interval.
(See "Recording Items" (p.62), "TIME PLOT Interval" (p.63))
2. Set the recording start time and end time (as necessary).
(See "Time Start" (p.58))
3. Press the key to start recording.
(To cancel recording, press the key again.)
(A folder will be automatically created, and the data will be stored there. See 9.3 (p.139).)
Save
destination:
SD memory card
File names:
Filenames are automatically created based on the start time and date and given an extension of
“ITV” (time series measurement normal binary data) or “FLC” (time series measurement flicker
data). Numbering starts at 0000 and goes to 9999.
Example: TP0000.ITV (the first set of time series measurement normal binary data saved in the folder)

Remaining storage time
The remaining storage time on the SD memory card being used is displayed when setting the recorded items
and TIMEPLOT interval. The time is calculated and displayed based on the SD memory card’s storage capacity,
the number of items being recorded, and the TIMEPOT interval time. This calculation does not take event data
into account, so the recording time may vary significantly with the number of events.
