Memory Utilization
This chapter presents formulas to calculate the amount
of memory used by the parameters that can be stored to
internal memory.
Out Of Memory Stop
In order to ensure that all measured data can be stored, the
LxT is stopped automatically when the amount of available
memory drops to 100 KB.
Overall Data
Each overall data block stored when performing a “Save
File” operation utilizes 27 kilobytes of memory.
Session Log
The amount of memory utilized, in bytes, when storing
session logs is calculated as follows:
52 + 12 *(Number of records)
where Number of records includes all Run, Pause, Stop,
Voice Message and Marker events.
Measurement History
The amount of memory utilized, in bytes, when storing
measurement histories is calculated as follows:
52 + Number of Measurement Histories* (Base
Measurement History Size + Optional Metrics)
Base Measurement History Size
Base Measurement History Size = 752 Bytes
Optional Metrics
1/1 Octave = 192 Bytes
1/3 Octave = 576 Bytes
Dose = 68 Bytes
