OVL, No Motion Time

• 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 104A-OCT)

• 1/3 Octave real time analysis - 28 filters with centre frequencies 20 Hz ÷ 10 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 104A-3OCT)

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

(as option called SF 104A-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 > 48 hours (display off, Bluetooth

off, octave analysis off)

• Extremely compact, lightweight and robust case with IP65 ingress protection
