Introduction
Anaheim Scientic’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. Designed
specically for measuring environmental, occupational and product
noise.
Model S660 meets the current International standard for sound level
meter performance IEC 61672-1:2002 Class 1. This standard directs the
inclusion of an A-frequency-weighting lter and frequency weightings of
C and Z (zero) frequency weightings.
Safety Precautions
Avoid taking measurements in hot, humid or wet places. Be sure the
temperature and humidity is within the limits indicated in the Technical
Specication section of this manual.
Avoid making measurements in the presence of explosive gas,
combustible gas, steam or excessive dust.
The following symbols are used in this manual:
Caution: refer to the instruction manual; improper usage
may damage the analyzer or its components
Meter is in compliance to the CE mark standards
Note: Read the recommendation which follows this symbol and the
instructions in this manual:
CAUTION
If the user does not observe this warning and/or operation instruction, it is
possible to either damage the instrument components or the user.
Do not operate the instrument in a hot temperature or humid
environment outside its specications. Refer to Technical Specication
page.

Windscreen
Wind blowing across the microphone can potentially add extraneous
noise to a measurement. Position the provided windscreen on the
microphone to prevent undesirable signals.
Keep the microphone dry and avoid severe vibration.

Input Interface
Microphone
The input uses an X9-6Z signal input receptacle. The receptacle pins
are arranged as shown below. The pins have the following functions:
Pin 1 Power supply
Pin 2 Null
Pin 3 Signal input
Pin 4 Null
Pin 5 Signal ground
Pin 6 Null
On the input receptacle, pin 1 is the power supply pin that the analyzer
uses to transmit power to the sensor (36 V, 2 mA max.). Inside this
power supply, a 2 kΩ current limiting resistor is connected in series.
The signal input pin receives the input electrical signal, in which a DC
isolated capacitor is connected (Maximum input voltage: 10 V (RMS),
input impedance: 150 kΩ, input capacitor: ≤100 pF). Two optional
extension cables are available to place the microphone away from the
unit: up to 5m (15 ft) Model MC15 or up to 20m (60 ft) Model MC60.
Microphone Extension Cables
Two optional microphone extension cables are available. Use these
to place the microphone strategically to avoid measurement deviation
caused by possible reection effects. The cable extends the microphone
for exact placement for correct measurements.
1. Turn the power off to the Model S660.
2. Turn the preamplier and microphone counterclockwise to be
separated from the main body.
3. Connect the extension cable to the microphone and main body.

C: The C weighting is essentially smooth used for measuring sound
level of acoustic material control in various environeme4nts. C weighting
is usually used for peak frequency measurements.
Z: The Z weighting is a at frequency response. A at measurement
with equal emphasis of all frequencies. It is a linear signal not processed
through a lter.
