Device functions

The sound level meter has various extra functions that make it easier to carry out
measurements using the device and also extend its range of application.
These extra functions are:
Auto power OFF function (clock symbol 2E)
In order to avoid that the operating life of the battery is shortened unnecessarily, an
automatic switch-off function has been implemented. The device is automatically
switched off if no button has been pressed over a period of about 15 minutes. You
can switch the device back on with the „Power" button.
This function can be turned on and off in measuring operation by pressing the
„SETUP" button.
HOLD function
The measured value currently being displayed is held in the display. The active func-
tion is shown in the display by „HOLD".
Press the "HOLD" button to activate this function. Press again to switch back to the
continuous measuring mode
MAX./MIN. function
With continuous measuring, the display only shows the maximum or minimum value.
This measurement function makes it easier for you to determine the peak level. The
active function is shown in the display by „MAX" or „MIN".
Press the button „MAX/MIN" to activate this function. Each additional press of the
button switches to the next display mode. MAX, MIN, normal measuring mode, MAX,
MIN...
Frequency weighting A/C line
The frequency of the measuring signal is weighted with the help of two benchmark
curves.
Line A represents the characteristic hearing line of the human ear. Humans perceive
deep sounds as quieter than mid or treble sounds.
