Page 2 Svantek provides this document “as is”, without warranty of any kind, either expressed or implied, including, but not limited to, its particular purpose. Svantek reserves the right to make improvements and/or changes to this manual, or to the products and/or the programs described in this manual, at any time.
Page 3 Note: If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Note: The SV 104A dosimeter contains no user serviceable parts. Opening product case invalidates the warranty. Note: When in normal use, always fit the SA 122A windscreen provided and make sure there is no display shipping protection foil in place.

Page 12 “Never before has a noise dosimeter been so accomplished yet so affordable, making your measurements more accurate and reliable than ever before”. To get started quickly with SV 104A, the first part of the manual describes basic noise dosimetry information followed by a guide to setting up the dosimeter and running measurements.
Page 13 SV 104A User Manual OUND PRESSURE The human ear responds to audible sound pressure levels in the range from 20 μPa (hearing threshold) to 20 Pa (pain threshold), resulting in the enormous scale 1:1 000 000. Since using such a large arithmetic scale is not practical, a logarithmic scale in decibels (dB) was introduced which is also in agreement with physiological and psychological hearing sensations.
Page 14 One of the most desirable SV 104A features is the unique data logging function that stores significant number of noise parameters at regular intervals and superimposed random vibration shock or audio events during...
Page 15 This makes checking for different regulatory bodies’ compliance and ensuring if hearing conservation programs are needed definitely easier than ever before. SV 104A answers all the important questions such as WHEN and HOW did the noise exposure appear? The data logging measurements can be started immediately, or they can be pre-programmed in advance so that measurement run can begin and end automatically at a pre-set start and end time without the need for any onsite supervision.

Page 20 SV 104A User Manual INDSCREEN When in use, it is strongly recommended that the SV 104A is fitted with the supplied SA 122A anti-static windscreen. To calibrate the dosimeter, it is necessary to remove the windscreen to gain access to the microphone.
Page 21 Unless required by local legislation, personal noise dosimeters should always be mounted on the shoulder, approximately 10 cm from the most exposed ear, with the microphone a few cm above the shoulder. The shape of the SV 104A and the height of the microphone ensure correct positioning of the instrument, see figure below.

Page 32 DOCK STATION CHARGING SV 104A can be charged using a dock station for a single unit (1-bay dock station SB 104B-1) or for five units (5-bays dock station SB 104B-5). Both dock stations are equipped with the USB type B connector and can be connected to a PC for data transfer using the SC 16 cable.
Page 33 SV 104A User Manual To charge SV 104A, place it on the dock station charger and ensure that the power cable is connected. SV 104A will automatically switch on the display during charging and show the amount of charge in the instrument.
Page 34 SV 104A User Manual EFORE YOU TURN THE INSTRUMENT ON There are only a few things to remember: • Ensure that the microphone is properly attached to the mounting head before switching on the instrument. • Always use the supplied SA 122A windscreen when measuring.
Page 35 Note: SV 104A will automatically shut down after 5 minutes in stopped mode. Note: If the auto-run (timer) mode is active, SV 104A will automatically stop measuring when the set time has elapsed and then switch off. If the auto-run mode is not used and no specific time has been set, the instrument will continue to measure until the battery is exhausted.
