Changing the microphone and windshield
To change the microphone, take off the windshield first (see chapter 3.3). Now, you need to unfasten
the microphone from the mounting head. Unscrew the microphone in a counter-clockwise direction.
To attach a new microphone, screw the microphone on clockwise until it fits tightly. It is critical to make
sure the sensor is tightly fitted. Be gently and be aware not to break or strip the thread.
Notice:
Note, When the microphone is changed, the new
microphone serial number
should be programmed into the
SV 104
internal memory. It can be easily programmed thru the freely
provided
SUPERVISOR
software.
In case the windshield is destroyed/lost by any accident, or it gets too dirty to afford the microphone
the best protection then
SVANTEK
offers
SA 122_3
three pcs per pack (windscreens for
SV 104
dosimeter).

SV 104
instrument
is turned off when it is stored.
Do not store the instrument permanently connected to the USB port. It shortens battery
