214
SETUP ACCORDING TO STANDARD
Setups in violation of the standard are indicated as
such on the display. You can then accept to apply the
default setup. Tone assessment will be made if
possible, in spite of standard violations. For tone
assessment according to ISO 1996-2, Annex D, you
can set the division between the Low and Middle
frequency range, the division between the Middle and
High frequency range, and the limits for the level
differences between adjacent bands.
For tone assessment according to DM 16-03-1998, the
tones are tested against loudness contours. Select
between ISO 226: 1987 Free-field, 1987 Diffuse-field
and 2003 Free-field
RESULTS
Tones are indicated above the spectrum when Tone is
selected as spectrum parameter. The resulting
adjustment can be viewed on the Value panel. It is not
saved with the measurement
QUALITY INDICATORS
On the display, a quality indicator (smiley) will indicate
that a hint is available for tone assessment quality.

Software Specifications – Low Frequency Option BZ-7234
Low Frequency Option BZ-7234 is enabled with a
separate license. It adds G-weighting and Building
Vibration parameters to Sound Level Meter, Frequency
Analysis, Logging and Enhanced Logging Software
and adds low frequency 1/1- and 1/3-octave analysis
to Frequency Analysis, Logging and Enhanced
Logging Software.
G-weighting
Specifications for G-weighing apply to Type 2250/2270
fitted with one of the microphone Types 4193 or 4964
(both with or without the Low Frequency Adaptor
UC-0211) and Microphone Preamplifier ZC-0032
Standards
