Saving Data
Real-time saving
Since setting the real-time saving to [On] allows data to be saved in a storage device
simultaneously with measurement, the instrument can perform measurement for a long period of
time regardless of the capacity of the internal memory.
The measurement condition settings are different between setting the real-time saving to [On] and
[Off] .
• When setting the real-time saving to [On] , you cannot use the following functions:
Automatic saving, trigger function, waveform calculation function, and memory division function.
• No storage device can be removed or replaced during the real-time saving.
• If displaying the message, Error No. 235 [Real-time saving could not be completed within
available time.] , the instrument may record abnormal data in a waveform file saved in a storage
device.
• The operation may be automatically restricted or the magnification may be changed if there is a
risk that saving data cannot be completed in time during the real-time saving.
• When any numerical calculation is set, only manual calculation can be executed.
After the measurement has been complete, select > [Calculation] > [Numerical
calculation] , and then tap [Execute] .
• For real-time saving, use the following Hioki’s options:
Model U8332 SSD Unit, Model U8333 HD Unit, and Model Z4006 USB Drive
Model Z4001 SD Memory Card (2 GB), Model Z4003 SD Memory Card (8 GB)
• When using Model Z4006 USB Drive for real-time saving, connect the drive to the USB 3.0
connector on the right side of the instrument. Connecting the drive to the USB 2.0 connector
cannot deliver the real-time saving speed specified in the product specifications.
Maximum recording time
• When the real-time saving is set to [On] , the maximum recording time is determined based on
the recording interval, the remaining capacity of a storage device, and the number of channels to
be used.
• When the sampling rate is set at a slow rate, the recording time is set to a long period of time
(one year or more) depending on a condition. The operation cannot be guaranteed because the
warranty period or product life may disturb it.
• When the external sampling is used, the instrument calculates the maximum recording time
assuming a recording interval of 10 MS/s.
See “Maximum recordable time when the real-time saving is enabled (values for reference
purposes)” (p. 361).
Waveform data
When recording waveforms with the real-time saving set to [On] , the instrument directly saves
measured waveform data (.MEM or .REC) onto a storage device. If the file size is large, the
instrument automatically divides the file into several files each of which has 512 MB and saves
them.
Deleting and saving files when saving data in real time
• If the capacity of the storage device becomes full while the instrument is storing files, it
automatically deletes waveform files created after the measurement has started beginning from
the oldest, securing free space in the storage device. However, when free space in a storage
device is less than the sum of the created file size and 512 MB before starting a measurement,
the instrument cannot overwrite any new files over the older files. Use a storage device with as
much free space as possible.
• The instrument does not delete waveform files saved in the past.
