S660 Users Manual Introduction Anaheim Scientific’s Model S660 is a Class 1 Integrating Sound Level Meter. This superior Class 1 Sound Meter offers a wider frequency range and a tighter tolerance over a Class 2 unit. This integrating meter sums the frequency-weighted noise to give sound exposure levels.
Confirm the instrument is undamaged. If damage is suspected, submit a claim to the dealer immediately. Check the packaged contents according to this list: Model S660 Sound Level Meter Figure 2 User’s manual Switching AC/DC power supply:...

S660 Users Manual SERVICE Storage It is possible the S660 may be stored in extreme environmental conditions exceeding the limits mentioned in Technical Specifications. It is recommended to allow the instrument to return to normal measuring conditions before using it for accurate results.
Anaheim Scientific will, without charge, repair or replace, at its option, defective product or component parts. Returned product must be accompanied by proof of the purchase date in the form of a sales receipt.
Line is the microhphone serial number that is set by the factory. LIne 2 is the microphone’s free field correction, which is set according to the type of microphone. Model S660 uses 1/2” free field microphone. Its correction between sound pressure field and free field is 0.15 dB at the frequency of 1 kHz.
Acoustical Calibration with CAL610 For the first acoustical calibration, set the calibrator sound pressure level according to the verification certificate of Anaheim Scientific’s Model CAL610 Sound Level Calibrator. In general, the sound level calibrator’s sound pressure level is 94.0 dB. When the measured sound pressure level is not 94.0 dB, calibrate by the actual result.
