Store Operation
Timer Auto (only when the VX-55EX is installed)
Executes Auto store by fi xed interval from the start time to stop time.
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
destroyed.
If an SD memory card is inserted in the slot while
the store mode is Manual, use of the internal
memory for store is not possible.
An SD memory card has to be inserted in the
slot while the store mode is Auto or Timer Auto.
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
L
v
store is executed with a store interval of 1 s on VM-55,
AS-60 calculates the time takt-max
L
v
of measurement data as
L
max
,
and takt-min
L
v
as
L
min
. To obtain the more accurate values of
L
max
and
L
min
, execute
L
v
store with a store interval of 100 ms. In this case,
L
max
and
L
min
are measured with
L
v
at every store interval of 100 ms.
