What is the difference between memory mode of [REC] and [AT/REC] that can be selected in the sound recording function (option) in the LA-3000 series?

1. Memory mode [RECORD (REC)]

This mode can be selected when the condition is as follows.
·LA-0354 Sound recording function (option) is added.
·The Operate Mode is selected as [Single] or [Dual].
When memory is performed in this state, one second interval of instantaneous sound pressure level of real sound data of [WAV data], time weight 10 ms and frequency weight Z is created as [CSV data]. This CSV data is used as a playback point when reproducing the recorded real sound data with LA-3000 series.

 

2. Memory mode [AT/REC]

This mode can be selected when the condition is as follows
·LA-0354 Sound recording function (option) is added.
·The Operate Mode is selected as [Single] or [Dual]. 
When memory is performed in this state, in addition to the real sound data and instantaneous, various calculated values of sound pressure level under the condition selected in the Operate Mode is created as [CSV data].

Note: When the data is stored in the [AT/REC] mode, if the measurement is interrupted before the selected measurement time is elapsed, the real sound data and instantaneous sound pressure level are stored up to the point of interruption. Please note that various calculated values are not stored.
