3.2 Start-up
In order to use the device, take it out of the carrying case and hold it with both hands. Place the
device on a table to make sure you do not drop it. You can then switch on the device with the
On / off key. When switched on, the device will open the menu.
3.3 Measuring surface
To start a measurement now, press “Start Sound Viewer” in the middle of the display. You will
then enter measurement mode. Where you have several options.
3.3.1 Intensity
In the upper left corner, you will find the intensity evaluation which depends on the sensitivity of
the sensors. Over time, the sensitivity automatically adapts to the current background noise. If
the cursor is in the blue or red area, it is not recommended to make a measurement as in this
case, the measurement values may be outside the common tolerances.
3.3.2 Data record
Under “Record” on the left side of the display, you can select the memory format, e. g. image,
video or Data to export You can find some more detailed information in chapter 3.3.7 data
records.
3.3.3 Sonometer
The sonometer function which you can find below the data record on the left-hand side of the
display, has 3 different modes:
- “Off” if you want to ignore this function
- “On – A filter” if you want to carry out a general sound level measurement using the A
filter which is adapted to the human auditory system
- “On – linear filter” if you want to measure the sound level without any filter in order to
get absolute values
3.3.4 Distance
The distance setting can be found in the lower left corner of the display. You can select between
two modes.
- The standard setting is “Auto”. This mode allows the device to determine the distance
within a range of 25 cm and 5 m.
- In “Manual” mode, you can set the distance manually to up to 50 m by 2-finger zoom.
3.3.5 Scan mode
You can find the scan mode option in the lower right corner of the display. If this option is
activated, four images are taken during the period of use. These show the highest measurement
values of the period of use. You can interrupt this process by using the “Play / pause” button.
This means that no measurement value and no image is taken until the option is reactivated.
3.3.6 Sampling rate
The possible settings for the sampling rate are “High Speed” or “Stable”. If you expect huge
differences or irregularities, the “High Speed” setting is recommended. If you expect the noises
to be stable, select the “Stable” setting. This will help you to get more accurate readings.
