The calibration system Nor1504A is capable of calibrating
virtually any type of sound measuring instruments, sound
calibrators and microphones in accordance with applicable
national and international standards.
The test system is operated by a MS-Windows bases PC
controlling the signal generator, voltmeter, test unit and the
device under test (DUT).
The computer also reads the barometer, the hygrometer
and the thermometer which all are included with the system
in order to provide the required environmental data in a fast
and accurate manner for the calibration reports.
A calibration of a sound level meter is normally divided
into two main parts: electrical calibration of the sound
measuring instrument and calibration of the microphone.
Eventually, an accompanying sound calibrator may be
calibrated and used for an overall system check.
The measured results are automatically logged and
used for an automatic generation of a calibration certificate
in MS-word format. If needed, the certificate may be edited
by the operator. Automatic generation of reported values
minimize the risk for errors generated by the operator.
