SV 258 PRO Building Vibration & Noise
Monitoring Station
What's inside?
The SV 258 PRO kit consists of two carrying
cases. The main unit is a waterproof carrying
case with internal 17 Ah battery and internal
charging unit supporting powering from exter-
nal DC or solar panel.
The SVAN 958A Class 1 sound and vibration
level meter is installed inside.
The outdoor charger and vibration accelerom-
eter kit are packed inside the second transpor-
tation case.
The kit includes license for SvanPC++ software
and a basic SvanNET account. Each kit has its
factory calibration certificate and 36 months
warranty card.
Dedicated Firmware
From September 2018 the SV 258 PRO can be
used with a new firmware for building vibra-
tion.
The new firmware simplifies setting up the sta-
tion in accordance to international and local
standards such as DIN 4150-3 or BS 7385-2.
The biggest advantage of the new firmware
is the real-time vibration events analysis in the
unit either with FFT or 1/3 octave and direct
comparison to criterion curves on-site.
In practise this means that station can gener-
ate alarms within a couple of seconds.

Building Vibration Events
When the curve selected for a given type of building is used as the event trigger,
the Peak Particle Velocity (PPV) and Dominant Frequency (DF) is compared against
the curve. If the PPV value exceeds the curve limit, the event starts and lasts in
accordance with the Event Duration setting. The Event Duration parameter should
be set accordingly to observed vibration type.
At the Event Start the Alarm Lamp, E-mail Alarm and SMS Alarm are activated. It
is necessary to activate at least one action: Lamp, SMS or E-mail in order to Start
an Event. The option Alarm Interval allows to set up a break-time before next SMS
or E-mail will be sent. The reduction factor works as the curve multiplying factor
and allows the curve to be moved up or down, so the alarm can be started earlier
or be postponed.
Example Event Settings
Trigger is set to DIN 4150-2, the build-
ing type, marked as Line 2 (L2).
Reduction Factor is set to multiplying
factor of 0.5 to shift down the L2 curve.
When the trigger condition is met, the
Alarm Lamp will turn on and stay on
for 1 second according to the setting
Hold Time.
When the trigger condition is met, one
SMS and one E-mail will be sent to Re-
cipient: Adam at the time of alarm.
Alarm Interval is set to 1 minute, so
the next SMS or E-mail would be sent
after 1 minute.
Event Duration is set to 4 seconds,
which means that the event will last 4
seconds starting from the trigger.
