In this manner a single microSD card with a capacity of 7.566 GB (nominal 8 GB) can save 4 entire
recording sessions (each 12 hours long) and an additional 6 hours (all together 4x12 hours + 6 hours, i.e.
2 days and 6 hours of recordings). This approach also works for other time intervals (not just 1 second),
maximizing usage of storage capacity on the selected microSD card.

Note: In case of recording with the interval shorter than 5 seconds, we recommend not to record
additional network events simultaneously with the recorder due to saving large files to SD card and lot
of processes needs to be done.
Note: Recorder file size is limited to 2 GB due to the FAT32 SD card formatting.
6.3.2
Waveform/inrush recorder
Sampling
7 kSamples/s, continuous sampling per channel. All channels are sampled
simultaneously.
Recording time
From 1 sec to 60 seconds.
Recording type
Continuous – consecutive waveform recording until user stops the
measurement or instrument runs out of storage memory. Max. 1500
records can be stored per session. Default setting is 200 records, more than
200 records can slow down the instrument.
