Product Data PD 1504A Ed3Rev0 Eng 0710 Nor1504A Calibration System - 1

Product Data for sound level meters, microphones and sound calibrators • Frequency response calibration of microphones using electrostatic or acoustical method • Sensitivity calibration of microphones using the insert voltage method ensures a high degree of accuracy • Fast and accurate calibration of sound calibrators, pistonphones and associated barometers in accordance with IEC60942 • Sound level meter calibration in accordance with IEC61672, IEC60651, IEC60804, DIN45657, ANSIS1.4, ANSIS1.43 and BS7580 • Fast and accurate calibration of sound measuring instruments using three different interface modes; manual; semi-automated and fully automated • Test of fractional octave filters in accordance with IEC61260 and IEC225 • Full test report generated • Built-in self test features • Turnkey system including all accessories needed. 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.
