Spartan 730/730IS Dosimeter Manual A-17
Table A-1 IEC 61252 Compliance
14.a
Recommended mounting is described in
4.3
Deploying the Dosimeter.
14.b
Each quantity measured has a descriptive
annotation preceding it. See
Measurement
Metrics (Overall) on page A-7
and
Measurement Metrics (DOSE) on page A-9
. See
also
Appendix B Glossary
for formulas for
quantities displayed.
14.c
See
SLM Performance on page A-8
for the
sound exposure range and sound level range.
14.d
The frequency response and tolerance is shown
in
A.1 Instrument Specifications
.
14.e
Extended frequency response and tolerance is
indicated in
A.1.1 Physical Specifications
and
graphed in
A.1 Instrument Specifications
.
14.f
The reference direction is perpendicular to the
plane of the microphone diaphragm.
14.g
The reference frequency is 1000Hz
14.h
The Calibration reference level is 114 dB SPL.
Calibration is done by level only, reference
integration time and reference sound exposure
are not applicable.
14.i
See 2.6 Calibration .
14.j
Acoustic testing is performed on a complete
Spartan 730 dosimeter. Using a comparison
coupler is recommended.
14.k
The means to insert electrical signals is
provided by using the ADP106 (Adapter input
BNC to 1/4-inch Mic 12 pF)
14.l
The electrical impedance of the source
connected to the ADP106 shall be 600
Ω
or less.
14.m
Free-field relative frequency response available
on request
14.n
Typical deviation between positive and negative
pulses is 2%
14.o
For information on the effects of temperature
and humidity variations, see Environmental
Conditions on page A-5 .
14.p
For information on Storage conditions, see
Environmental Conditions on page A-5 .
14.q
With the unit in the normal mode of operation,
the sound exposure level of the unit was not
affected when exposed to a magnetic field of 80
A/m for 1 hour.
14.r
Operating the Spartan 730 in proximity to a
source of electromagnetic radiation may cause
up to 1.5 dB variation in the sound exposure
reading. This meets all of the standards in
section 15 of IEC 61252 (2017) at a sound level of
85 dB.
14.s
See
Battery
for battery information
14.t
Verification that there is sufficient energy to
complete a measurement is in section
14.u
The recommended interval for periodic testing
of this dosimeter to verify it’s acoustical and
electrical performance characteristics is 1 year.
14.w
The immunity to power- and radio-frequency
fields and to electrostatic discharge is less than
85 dB.
14.x
No cables or accessories are essential to take a
measurement.
14.y
The normal mode of operation is the Spartan
730 running a measurement while set up in the
reference orientation with Time History
enabled.
14.z
Operating the Spartan 730 in proximity to a
source of electrostatic discharge causes no
discernible variation or difference in the
functionality of the dosimeter.
14.aa
The reference orientation is angling the unit at
45 degrees so that the microphone is pointing
up. The unit is facing toward the radio frequency
electromagnetic field emitter or receiver.
14.bb
The mode of operation of the Spartan 730 that
produces the greatest radio frequency emission
levels is with the unit set to run with the LCD
light on, while being charged by an external
wireless charger.
14.cc
The mode of operation of the Spartan 730 that
produces the least immunity to the effects of
radio frequency fields is with the unit running in
normal mode of operation, except that the
microphone is facing 90° from the
electromagnetic field emitter.
