In situ calibration
It is advised to perform an acoustic calibration of the instrument each time before and after
the measurement run. A single calibration at the start of each day of use is usually sufficient for most
regulations. See chapter 4.7 for calibration details, please.
Notice:
With use of a
SV 34
calibrator the calibration can be performed only in safe area.
6.4
Periodic testing
The manufacturer’s recommended factory calibration interval is every
12 months
for
SV 104IS
to be confident in its continuing accuracy and compliance with the international specifications.
Notice:
Please contact your local SVANTEK distributor for further details on traceable
recalibrations that are recommended by most regulatory authorities.

Changing the microphone and windshield
To change the microphone, unscrew the windshield first (see chapter 3.3). Now, you need to unscrew
the microphone from the mounting head in a counter-clockwise direction with use of a technological wrench
NM104I1Z
.
To attach a new microphone, screw the microphone on clockwise until it fits tightly with use of
mentioned above technological wrench. It is critical to make sure the sensor is tightly fitted. Be gently and be
aware not to break or strip the thread. Then proceed to mount the windshield in a counter-clockwise direction
until it stops firmly.
Notice:
Changing the microphone and/or windshield is only allowed in safe area.
Notice:
Note, when the microphone is changed, the new
microphone serial number
is automatically programmed into the
SV 104IS
internal memory.
In case the windshield is destroyed/lost by any accident, or it gets too dirty to afford the microphone
the best protection then
SVANTEK
