SV 977D User Manual
Calibration by
Sensitivity
Type of calibration with the use of microphone’s
published sensitivity information. This calibration doesn’t
perform any calibration measurement and doesn’t
require any calibrator.
Chapter
3.3.2, 3.3.3
Sensitivity
Transducer’s sensitivity, given by the producer, which
should be set during the Calibration by Sensitivity. For
microphones the sensitivity is usually given in mV/Pa and
for accelerometers – in mV/ms
-2
.
Chapter
3.3.2, 3.3.3
Calibration Factor
A value which the sensor reading has to be multiplied
with to get the correct reading. In the instrument, the
calibration factor is presented in dB, therefore it is always
added to the results.
Chapter
3.3.2, 3.3.3
Calibration by
Measurement
Type of calibration based on the reference signal
measurement with the use of a microphone or
accelerometer calibrator.
Chapter
3.3.4, 3.3.5
Calibration Level
Level of the reference signal generated by used
calibrator.
Chapter
3.3.4, 3.3.5
Calibration Result
Measured by the instrument reference signal level
without calibration factor correction.
Chapter
3.3.4, 3.3.5
Calibration
History
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.
