Note: Only Z weighting is recorded for spectrums as frequency weighting can be applied in post-

processing.

Post-Processing Options

The available operations for this record mode on post-processing are:

• Limited event masking on the time-history

• Limited redefinition of averaging periods

• Calculating statistics on SPL

8.4.2 Sampling Rate

8.4.2.1 Instantaneous Record Mode

In Instantaneous Record Mode, the data rate can go from 10 ms to 1 s.

Some sampling rates may not be suitable for some measure types. If such a combination occurs, a

warning is displayed but does not prevent the user from proceeding with measurement. For

example, a sampling rate of 1 s is not suitable to correctly reproduce the Fast SPL as it is subject to

vary more rapidly in time.

The FFT rate is set automatically from 256 ms, 512 ms or 1024 ms according to the selected Sampling

Rate.
