The microphone is equipped with an ICCP power supply. Current technical data of
the power supply: 4 mA, 24 V. Voltage over 30 V may cause damage to the micro-
phone. The SW 1000/SW 2000 sound level meter is equipped with an internal ICCD
power supply which allows a direct connection of a microphone.
Connect the microphone to the TNC connector. Then turn it on the thread, firmly
connecting both elements.
2.3 Wind shield
The sound level meter is supplied with a WS002-9 wind shield used outdoors in
windy environments. Do not use the wind shield if the environment is not exposed to
wind (e.g. when performing measurements indoors).
Firmly press the wind shield onto the microphone all the way, as shown in the figure
above. Further details concerning the wind shield correction outdoors are specified in
Appendix 4.
2.4 Data socket and power socket
The bottom part of the sound level meter includes 7 sockets. Open the rubber cover
to see them.
PWR:
Standard DC power socket (diameter: 2.1 mm) allows you to connect an external
