|
30 - 130 dB |
|
Resolution |
0.1 dB. |
|
Accuracy (23 +-5 C)
|
Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB ( 31.5 Hz to 8 KHz), then the accuracy of frequency weighting is specified as following: 31.5 Hz: +- 3 dB, 63 Hz: +- 2.5 dB, 125 Hz: +- 2.0 dB
250 Hz: +- 1.9 dB, 500 Hz: +- 1.9 dB, 1 kHz: +- 1.4 dB
2 kHz: +- 2.6 dB, 4 kHz: +- 3.6 dB, 8 kHz: +- 5.6 dB

|
Frequency Weighting Network
|
A weighting: The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level measurement, always select to A weighting. C weighting: The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment.
