Standards on page 8
Note: The International IEC Standards are adopted as European
standards by CENELEC. When this happens, the letters IEC are
replaced with EN and the number is retained. Type 2250/2270 also
conforms to these EN Standards
CHANNELS (TYPE 2270 ONLY)
All measurements are made from either Ch.1 or Ch.2 or both
simultaneously
TRANSDUCERS
Transducers are described in a transducer database with information on
Serial Number, Nominal Sensitivity, Polarization Voltage, Free-field Type,
CCLD required, Capacitance and additional information.
The analogue hardware is set up automatically in accordance with the
selected transducer
CORRECTION FILTERS
For microphone Types 4189, 4190, 4191, 4193, 4950 and 4952,
BZ-7228 is able to correct the frequency response to compensate for
sound field and accessories
Broadband Analysis
DETECTORS
A- and C-weighted: Broadband detectors with Fast exponential time
weighting
Overload Detector: Monitors the overload outputs of all the frequency
weighted channels
Under Range Detector: Monitors the under range of all the frequency
weighted detectors when set to High Range. Under range is set if level is
below lower limit of Linear Operating Range
Type 2270: Detectors available for both Ch. 1 and Ch. 2
