Note
Relationship between elapsed measurement time
and number of data
When using Auto mode and 100-ms sampling, 10 data
sets are stored per second. Therefore, when 10 seconds
of measurement time have elapsed, the number of
stored data is 100 (10 when using 1-second sampling).
During Auto mode, the pause function cannot be used.
During Auto mode, the address indication is based
on number of
L
eq
calculation. The number of
L
eq
calculation is not displayed when
L
eq
calculation
interval is OFF.
