3 FUNCTIONS OF THE INSTRUMENT – Function
In the Function section, you can select a
measurement mode (Mode) which relates to
the transducer type, a measurement
function (Measurement Function) and
perform the instrument check or calibration
(Calibration).
3.1 SELECTING THE INSTRUMENT MODE – MODE
The instrument can work in four modes – two
sound modes: Sound Meter and
Direct Sound; and two vibration modes:
Vibration Meter and Direct Vibration.
The Mode relates to the type of transducer connected to the instrument: microphone with preamplifier or
accelerometer. Sound Meter and Vibration Meter modes relates to the Svantek standard accessories, while
Direct Sound and Direct Vibration modes enable using of other manufactures’ transducers.
Input modes are connected with IEPE current settings (see Chapter 7.7).
Note: The instrument doesn’t recognize the type of transducer, connected to its input socket.
Remember to switch the Mode all the time you change the transducer.
Note: In the manual text the Sound mode (or Sound measurements) refers to the Sound Meter
modes and the appropriate functions dedicated to the measurement and analysis of the acoustic
signal: Level Meter, 1/1 Octave, 1/3 Octave, FFT etc.; the Vibration mode (or Vibration
measurements) refers to the Vibration Meter modes and the appropriate functions dedicated for
the measurement and analysis of the vibration signal: Level Meter, 1/1 Octave, 1/3 Octave, etc.
3.2 MEASUREMENT FUNCTIONS OF THE INSTRUMENT – MEASUREMENT FUNCTION
The main function of the instrument is the measurement of Sound pressure or Vibration broad band levels
(Level Meter). The Sound Level Meter (SLM) meets the standard IEC 61672-1:2013 for Class 1 accuracy and
the Vibration Level Meter (VLM) meets the standard ISO 8041-1:2017. The instrument can also be used for
medium to the long-term monitoring using the huge capacity data logger in which all measurement results can
be stored.
You may also use 1/1, 1/3, 1/6 and 1/12 real time octave band or FFT frequency analysis functions. These
functions extend the main broad band Level Meter functions of the instrument, because the analysis is
performed along with all calculations of the broadband Level Meter results.
The instrument offers also specialized functions dedicated for the reverberation time (RT60), loudness
(Loudness) and speech transmission index (STIPA) assessments.
To activate a function, open the
Measurement Function list, select the
required function and press <ENTER> to
confirm selection.
Note: It is not possible to change the measurement function during a measurement run. In this case,
the instrument displays for about 3 seconds the message: “Measurement in Progress”. To change
the function of the instrument the current measurement must be stopped!
