Using the Logging Function

The logging function allows accumulating measurement values while skipping some of them. It is used to
observe the fluctuation in measurement results over an extended period of time using the Trend Monitor
and Profile Monitor screens.
The amount of data generated in one measurement is different for the Trend Monitor and Profile Monitor
screens. The maximum amount of accumulated data for each monitor screen is as follows.

Trend Monitor screen
Profile Monitor screen
Example 1: Accumulation of data once every 300 measurements
Data can be accumulated for up to 30 seconds when the logging function is not used. If the setting
is changed to "accumulate once every 300 measurements" using the logging function, it is possible
to accumulate data for a day because 100 ms × 300 × 3000 = 90000 sec = 1500 min = 25h.
