Three instruments in one
– ACOUSTIC PROFILE concept
SV 104A
is able to monitor and log noise by enabling up to three different parameter configuration
settings, a
lso referred to as “
ACOUSTIC PROFILE
”. One can set profile no 1 to run measurements using the
OSHA HC (Occupational Safety and Health Administration - Hearing Conversation) parameters and at the
same time set profile no 2 to monitor the noise with the OSHA PEL (Occupational Safety and Health
Administration
– Permissible Exposure Level) parameters while profile no 3 is set to ACGIH parameters. This
is the true triple instrument in one.

The VIEW mode presentation concept
Such an advanced noise dosimeter as the
SV 104A
offers a large amount of parameters for the operator
to inspect. Therefore, all information is divided in a neatly organized manner as VIEW modes for each
PROFILE.
The VIEW
mode is a way in which the measurement parameters are presented to the operator. In other
words, when you change the VIEW mode, specific measurement parameters and status information will be
presented in different manner as distinct screen content.
SV 104A
features the following VIEW modes, where most of them can be individually disabled:
▪
Running instantaneous SPL view mode ( 3.9.1)
- can be disabled with PC software
▪
Primary
“one-result” parameters view mode ( 3.9.2)
- cannot be disabled
▪
Results list view mode ( 3.9.3)
- can be disabled with PC software
▪
Octave analysis spectrum LEQ view mode ( 3.9.4)
- can be disabled with PC software
▪
Octave analysis spectrum MAX view mode ( 3.9.4)
- can be disabled with PC software
▪
1/3 Octave analysis spectrum LEQ view mode ( 3.9.5)
- can be disabled with PC software
▪
1/3 Octave analysis spectrum MAX view mode ( 3.9.5)
- can be disabled with PC software
▪
Instrument Status view mode ( 3.9.6)
- can be disabled with PC software
3.9.1
Running SPL view mode
Running SPL presentation mode is used when measurement run is not actually running, that is when
the instrument is in standby mode before or after a measurement. In this mode the current SPL result is
calculated and displayed, but not stored in the instrument's memory. The purpose of this information is to give
the user a first indication of the sound levels about to be measured. This can be useful for some
measurements. The instrument behaves as a simple general purpose sound pressure level meter in this view
mode.
