Measurement data (TIME PLOT data)
<Automatic data recording compression function>
This function begins recording at one-second intervals and automatically lengthens the
recording interval to up to an hour as internal memory fills. This function helps to ensure
that suitable data quantities are acquired for analysis, whether the overall measurement
period is short or long. This function supports continuous measurement sessions of up to
about 125 days.
Measurement data (EVENT data)
<Recordable Number of Events>
The number of events that can be recorded is as follows regardless of whether internal
memory is partitioned.
