Appendix 6 Maximum Recordable Time
A
12
When saving waveform files in the form of binary data to either the instrument’s internal
memory or the CF card or USB flash drive, maximum recording times are as follows.
The recording time when data obtained through 10 analog channels, four pulse
channels, and one alarm channel (no waveform calculation channels) are recorded
is shown in the table below as an example. Maximum recording time is inversely pro-
portional to the number of recording channels.
Because the header portion of waveform files is not included in these calculations,
actual times should be expected to be about 90% of the listed values.
Day values beyond 365 are not shown in the table.
When saving data in text format (CSV), the maximum recording time is reduced to 1/
10 of the value indicated in the table or less.
