Analysis
DETECTORS
Parallel detectors on every measurement:
A- or B-weighted (switchable): Broadband detector
channel with three exponential time weightings (Fast,
Slow, Impulse), one linearly averaging detector and
one peak detector
C- or Z-weighted (switchable): As for A- or B-
weighted
Overload Detector: Monitors the overload outputs of
all the frequency weighted channels
MEASUREMENTS FOR SOUND INPUT
X = frequency weightings A or B
Y = frequency weightings C or Z
V = frequency weightings A, B, C or Z
U = time weightings F or S
Q = exchange rate 4, 5 or 6 dB
N = number between 0.1 and 99.9
For Storage Full statistics
For Display and Storage:

station):
Only for Display as Numbers or Quasi-analog

IEC 60651: A-weighted: 23.5 dB to 122.3 dB
Linearity Range: In accordance with IEC 60804:
A-weighted: 21.4 dB to 140.8 dB
Linear Operating Range: In accordance with
IEC 61672:
• A-weighted: 1 kHz: 24.8 dB to 139.7 dB
• C-weighted: 25.5 dB to 139.7 dB
• Z-weighted: 30.6 dB to 139.7 dB
Peak C Range: In accordance with IEC 61672: 1 kHz:
42.3 dB to 142.7 dB
