Store Operation
The NL-42/NL-52 can store measurement data (processed data such as sound
level and equivalent continuous sound level, and measurement parameters
such as frequency weighting and time weighting characteristics) in the internal
memory or on SD memory card.
This chapter describes how to store data in memory and how to recall data from
memory. There are three different modes of storing data, as listed below.
When the optional Extended Function Program NX-42EX is not installed,
only the manual mode can be operated.
Store names can not be set when no SD memory card is inserted.
Important
Use SD memory cards provided by Rion. The
performance of other cards will not be guaran-
teed (see page 96).
Manual
All processed data except sound level are considered as a single data set, and
an operator stores the data set one-by-one manually.
When an operator performs store operation after a measurement, each processed
value and measurement condition will be stored with the time value.
If no SD memory card is inserted, the data will be stored in the internal
memory of the unit. If an SD memory card is inserted, the data will auto-
matically be stored on the card.
Internal memory capacity: max. 1000 data sets
SD memory card capacity: max. 1000 data sets per store name, max. 100
