Calibration Factor
Difference between the reference signal level and the
measured level. The calibration factor is always added to
the results and measurement range limits.
Chapter
3.3
Last Calibration
Records of previously performed calibrations of the
instrument. Each record contains information about
calibration date and time, calibration type, calibration
factor etc.
Chapter
3.3.6
Clear Calibration
History
Operation that clears all calibration records.
Chapter
3.3.7
Auto Calibration
Feature that enables automatic calibration when the
reference sound or vibration signal is detected by the
instrument.

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.
