Data Logging
The measurement results of data logged in chronological order at 1-minute intervals (total
flow rate, average flow rate, fluctuation coefficient, ambient pressure, pressure loss, ambient
temperature, generation of warning) can be checked by using the LV-250/40B
communications cable (
optionally available
) provided with the software. Note, however, that
data logged in chronological order at 1-minute intervals may or may not be logged according
to the ON/OFF timer settings.
* As the average flow rate and fluctuation coefficient (flow rate) measurement values,
the values calculated up to respective times from since pump operation was started
are recorded. Also, for measurement values other than warnings, 1-minute interval
average values are recorded.

The maximum data logger time is 133 hours. Also, the maximum sampling count is 99. When
the remaining memory time that is displayed after sampling is stopped has fallen below one
hour, or the number of files displayed in the Previous Data menu has reached 99, clear
memory (Clear Logs). (
For details, see P38.)
* Data that can be checked by Last Data in the main menu is saved. Note, however, that
this is not necessarily so in the case of a power fault. (
For details, see P50)
