SV 104 USER'S MANUAL_DRAFT_______________________________________________

2 KIT COMPONENTS

2.1 SV 104 dosimeter short form specification

 Acoustic Dosimeter conforming to international standards IEC 61252; ANSI S1.25;

 Class 2 Microphone, MEMS type: SV27, 1/2" housing

 OLED colour display with super brightness and contrast

 Large 8GB memory

 USB 2.0 high speed interface

 Parallel Slow, Fast, Impulse detectors for the measurements with A, C, Z filters

 Frequency Range 30 Hz ÷ 8 kHz

 Measurement range 55 dBA RMS ÷ 140.1 dBA Peak

 Dynamic Range 80 dB

 Exchange rates 2, 3, 4, 5, 6

 Measurement results: Run Time, Lpeak, Lmax, Lmin, Lp, DOSE (%), D_8h, PrDOSE, Lav, Leq,

LAV, LE, SEL8, E, E_8h, LEPd, PSEL, Ltm3, Ltm5, Lstat, PTC, PTP, ULT, TWA, PrTWA, Lc-a

 3 independent user configurable acoustic measurement profiles

 Easy in use predefined setups

 Time-history data logging of Leq/Lav/Lmax/Lmin/Lpeak with variable 0.1 s to 1 hr logger step and

separate summary results intervals with statistical levels

 1/1 Octave real time analysis - 9 filters with centre frequencies 31 Hz ÷ 8 kHz, Type 2 – IEC 1260;

presented as a bar graph with Leq and Lmax band levels plus overall A, C and Z broadband

weightings (as option called SF 104-OCT)

 Audio events recording, triggered and continuous mode, 12/24 kHz sampling rate, wav format (as

option called SF 104-WAV)

 Voice Comments records audio on demand, created before or after measurement, added to

measurement file

 Vibration shock detector with user selectable variable threshold: 1g-15g

 Automatic acoustic field calibration with one touch activation before and after measurement

 Operational time > 40 hours (display off, octave analysis off)

 Extremely compact, light weight and robust case with IP65 ingress protection
