Draft Shield; Data And Power Supply Connection - sauter KERN SW 1000 Instruction Manual

SW-A01:
Pre-polarized measuring microphone 1/2", class 1. sensitivity: 50 mV/Pa. Frequency
range: 10 Hz to 20 kHz. Common housing with ICCP preamplifier, power supply 4
mA/24 V.
SW-A02:
Pre-polarized measuring microphone 1/2", class 2. sensitivity: 40 mV/Pa. Frequency
range: 10 Hz to 12.5 kHz. Common housing with ICCP preamplifier, power supply 4
mA/24 V.
Microphone and preamplifier are screwed together by a thread. Do not separate the
parts except in special cases. The microphone is a precision measuring sensor,
prolonged contact with high humidity or dusty environments can damage the
microphone. When the microphone is not in use, store it in the box provided.
The microphone has an ICCP power supply. The current technical data for the power
supply are 4 mA, 24 V. If the voltage exceeds 30 V, the microphone will be damaged.
The SW 1000/ SW 2000 sound level meter has an internal ICCD power supply to which
the microphone can be connected directly.
Connect the microphone to the TNC connector. Then turn the thread until the parts are
firmly connected.

2.3 Draft shield

The sound pressure meter is equipped with a WS002-9 draft shield for use in windy
outdoor areas. The wind shield need not be used if no wind is expected in the
surrounding area (for example, when measuring indoors).
Press the windscreen firmly onto the microphone as shown in the figure above until it
stops. See Appendix 4 for more details on how to adjust the windshield outdoors.

2.4 Data and power supply connection

There are 7 interfaces on the bottom of the sound pressure meter. Open the rubber
cover to see these interfaces.
