BRUEL & KJAER 2203 Instructions And Applications

is greater than 50 dB (except in the four most sensitive ranges) and the
output voltage corresponding to full scale deflection is 3,16 V RMS .
Consult the Instruction Manual of the appropriate Level Recorder
(Type
2305 cr 2307) for detailed operating procedures.
For use
of the 2203 and Level Recorder with the Statistical Distribu-
tion Analyzer 4420 see the 4420 Instruction Manual.
7.3. NOISE DOSE METER
The Noise Dose Meter 4423 determines a noise dose based on both
the time and amplitude of exposure to noise as specified by various DIN,
ISO,
and English standards . It is designed to operate with a Sound Level
Meter such as the 2203. Since noise dose measurements are com-
monly made over periods of several hours, provision is made to power
the 2203 from the Noise Dose Meter.
See the 4423 Instruction Manual for details .
7.4. TAPE AND DIGITAL RECORDING
When tape recording is required for remote recording and data stor-
age, frequency transformation, and later analysis, the 2203 serves as a
high quality input to a portable, battery operated recorder such as the
B & K 7003 or 7004.
Always adjust the tape recorder gain for best dynamic range without
overload, and record a reference level to which all attenuator range
changes of the 2203 can be referred.
For
the recording of impulsive or single event sounds the Tape Loop
Cassette UD
0035 may be used with the 7003/04. However , the ideal
and most flexible approach to impulse recording is the Digital Event Re-
corder
7502 which provides an extremely wide range of frequency
transformation and also permits recording of information before the trig-
ger .
