Store Operation
Timer Auto (only when the NX-42EX is installed)
Executes Auto store using the set start time and recurrence interval of trigger
event.
When the following one of conditions occurred, the store is stopped and data
is saved.
• When the total measurement time reached the 1,000 hours.
• When the
L
eq
store reached 999,999 sets.
• When the capacity of the SD memory card became insuffi cient.
Important
Never turn off power to the unit or remove the
SD memory card while a store operation is in
progress. Otherwise internal data can be de-
stroyed.
When an SD memory card is inserted in the
memory card slot of the unit, use of the internal
memory for store is not possible.
Note
A processing start time is used for a time stamp of
measurement and processed data. For example, when
performing one-minute processing with
L
eq
store,
the time stamp 00:01:02 indicates that the data is
obtained for one minute from 00:01:02.
Notes for using the data management software AS-60
• Since AS-60 cannot read Manual store data, perform measurement with
Auto or Timer Auto store to handle measurement data using AS-60.
• When setting the
L
p
Store Interval to 200 ms or 1s on the NL-42A/
NL-52A, the AS-60 software calculates the maximum
L
p
as
L
max
and
the minimum
L
p
as
L
min
from within the measured period.
If you require precise
L
max
,
L
min
values, please set the
L
p
store interval
to 100 ms.
With this setting,
L
max
,
L
min
are measured simultaneously with
L
p
at
every
L
p
store cycle.
