1.2 Applications

 Simple noise measurements
 Determination of environmental noise
 Product quality control
 Assessment of technical activities for noise reduction

1.3 Functions

 Class 1 (SW 1000) and Class 2 (SW 2000)
Sound Level Meter
 Meets the requirements of IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-
1997
 The 1/1-octave analyser is in accordance with IEC 61260-1:2014 and ANSI S1.11-
2004
 Linearity range: 20 dBA to 134 dBA (SW 1000), 25 dBA to 136 dBA (SW 2000)
 Dynamic range: above 123 dB for SW 1000 and above 122 dB for SW 2000
 Frequency weighting: A/B/C/Z; time constant: fast/slow/pulse
 3 profiles and 14 measurements defined by the user and calculated simultaneously
with different frequency weightings / time constants
 Calculation of SPL, LEQ, Max, Min, Peak, SD, SEL and E values
 LN statistics and display of the time curve
 User-defined integral interval measurement up to a maximum of 24 hours
 Extremely fast ARM processor with a floating-point coprocessor, ensuring a wide
frequency response, high dynamic range and low own noise
 MicroSD (TF) card with 4 GB capacity as a bulk storage carrier
 RS-232 remote control interface
 Thermal mini-printer for printing of measurement data
 Internal GPS module (option), GPS time support
