5.1 Average
An average data is calculated by summing the measured values (momentary values) acquired
every 1 second for a specified calculation period, and then dividing the cumulative total by the
data counts.
There are three AVERAGE data (AVERAGE 1 to AVERAGE 3), calculated using different cal-
culation periods. And these calculation results can be checked on the respective AVERAGE
screens.
Table 1 AVERAGE types
Note

If the data counts exceeds the data capacity, the oldest data will be automatically deleted.

The time displayed on the AVERAGE screen is the final data acquisition time.
Pressing the [AVERAGE 1], [AVERAGE 2], or [AVERAGE 3] on the MENU/DATA screen
displays the screen showing the latest data.
