During the recording process the recording icon ( ) will appear on the screen.
The DC112d/DC112 saves the following values once each integration period (T) has
finished:
• Equivalent continuous sound pressure level with A frequency weighting (L
AT
).
• Equivalent continuous sound pressure level with C frequency weighting (L
CT
).
• Equivalent sound pressure level corresponding to the last T integration interval, with or
without frequency weighting (A) for each one of the octave bands centred on frequencies
63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz. (Only DC112)
• Peak sound pressure level of the T integration interval with C frequency weighting (L
Cpeak,
T
).
When the measurement ends, the final results are saved:
• Equivalent continuous sound pressure level with A frequency weighting corresponding to
the measurement time (L
At
).
• Equivalent continuous sound pressure level with C frequency weighting corresponding to
the measurement time (L
Ct
).
• Equivalent continuous sound pressure level with the integration time corresponding to the
measurement time, with or without A frequency weighting for each one of the octave bands
centred on frequencies 63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz. (Only DC112).
• Overall peak sound pressure level with C frequency weighting corresponding to the
measurement time (L
Cpeak
).
• Equivalent daily noise exposure level (L
EX,8h p
).

The storage capacity according to the programmable integration time is shown in the
following table.
Storage capacity

T= 10 s 11 months 7 days
The storage times for each type of recording correspond to one single recording, until the
memory is completely full.
When the built-in memory is full, no more recordings can be made and no more final results
saved. If you attempt to do this, the ‘MEMORY FULL’ message will appear on screen.
If the battery of the DC112d/DC112 runs out during a recording, the DC112d/DC112 will
interrupt the recording (PAUSE), show the message “BATTERY FLAT” on the screen and
switch off. To continue the measurement, see section
3.2.1.
If the power source of the DC112d/DC112 is cut off suddenly during a recording, (removal of
the battery, or the USB connection), the recording will be incomplete. It will not be able to be
