Post Calibration
Feature that enables performance of additional
calibration in the end of the measurement session and
add the new calibration factor to some files already saved
in the instrument’s memory.

Elapsed time
Time from the measurement start, that is displayed in the
right upper corner of the display in the format
󰑺󰑻󰑼󰑽mm:ss
in the range from 00:00 to 59:59, or in the format
󰑺󰑻󰑼󰑽hh:mm:ss in the range from 01:00:00 to 99:59:59, or
in format
󰑺󰑻󰑼󰑽xxxh from 100h to 999h, and 󰑺󰑻󰑼󰑽>999h if the
elapsed time exceeds 999 hours. Its maximum value is
equal to the Integration Period and the elapsed time is
zeroed when new measurement cycle starts.
Chapter
5.1
Ovl
Percentage of the overloaded input signal, which
occurred within the elapsed measurement time.
Appendix D
D.1.2
Peak
For sound measurements: Peak Sound Level, the
greatest instantaneous value of a standard frequency
weighted sound pressure level within the elapsed
measurement time.
For vibration measurements: the greatest instantaneous
value of a standard frequency weighted vibration
(acceleration, velocity or displacement) within the
elapsed measurement time.
Appendix D
D.1.2,
D.2.2
Spl
Sound Pressure Level, the maximal value of the
frequency and time-weighted sound pressure level at the
exponential RMS detector output for the last second.
Appendix D
D.1.2
Max
For sound measurements: maximal value of the time-
weighted sound pressure level at the exponential RMS
detector output within the elapsed measurement time.
The Max result for the 1 second period is equal to the Spl
result.
For vibration measurements: maximal value of the time-
weighted vibration (acceleration, velocity or
displacement) level at the exponential RMS detector
output within the elapsed measurement time.
Appendix D
D.1.2,
D.2.2
Min
Minimal value of the time-weighted sound pressure level
at the exponential RMS detector output within the
elapsed measurement time.
