1.5 Memory
The sound level meter has three kinds of memory
● Set-up
● Buffer
● Records
1.5.1 Set-up Memory
The set-up memory is used to store the date and time, last
settings used, and the language selection. This memory is
maintained by the backup battery, so it is saved when you
turn off the instrument. The date and time are stored directly
in the real time clock, which is also powered by the backup
battery.
1.5.2 Buffer
Holds all of the measurement results from the last measure-
ment period. It is cleared each time you start a measurement
or turn off the sound level meter. Results in the buffer can
be output to a printer or copied into a record.
1.5.3 Records
Up to 40 records of measurement results can be stored in
memory. Records are copied from the buffer. They can be
stored automatically (after a preset-timed measurement) or
manually (at any time after a measurement is stopped).
The records are stored in non-volatile memory, which is pow-
ered by the backup battery. All records are preserved when
you turn off the instrument.
