range: Leq linearity range, Leq dynamic
range and Peak range for 1 kHz.

measurement ranges parameters is given in
Appendix C.

The values of ranges in sound modes
depend
on the settings in the
Compensation Filer screen ( path: <Menu>
/ Measurement / Compensation Filter ) and
the calibration factor.
For example, if the calibration factor is equal
to 0.5 dB, the
High range will be changed as
shown on the attached screen.

The right-hand screens present the Range
for the Vibration mode and zero calibration
factor.
Nonzero calibration factor always shifts the
lower and upper limits of the ranges for
vibration modes.
