)
WARNING! The extents of measurement range for peak level at A and Z
frequency weightings are determined for continuous 1000Hz sine signal;
measurement error extended by expanded measurement uncertainty is less than 1.1
dB.
Self-generated noise
- measured with electrical input facility installed:
° at A frequency weighting
13dB
° at C frequency weighting 19dB
° at Z frequency weighting 25dB
- measured with WK-21 microphone installed:
° at A frequency weighting
19dB
° at C frequency weighting
24dB
° at Z frequency weighting
27dB
