ENTER key
The ENTER key confirms the selected parameter. When setting parameters from the menu, to quit
setting without saving a parameter, just press any key except
SELECT, ENTER and the four ar-
rows , or press MENU. Factory setup is loaded into the sound level meter by turning it on while
holding the ENTER key
RIGHT key
The RIGHT key selects the next character in the active line of the menu. It jumps to the next pa-
rameter during the selection of a measuring variable that needs the definition of more than one pa-
rameter (see SELECT). It expands (ZOOM+) the vertical scale of frequency spectra graph.
DOWN key
The DOWN key selects the next line in the menus or decreases the selected parameter. Increases the
vertical scale limits of frequency spectra graphs moving the data downwards.
CURSOR (Keypad)
It activates the cursors in a graph. Press it repeatedly to activate in sequence: the first cursor L1, the
second one L2 or both of them in “tracking” (
Δ L). To disable the cursors, press the key again.
Use the LEFT and RIGHT key of the keypad to move the flashing selected cursor over the graph.
Relevant values are shown at the top of the display.
When the instrument works as spectrum analyzer, the display shows, starting from the left, the se-
lected measuring parameter together with the sound level and the nominal frequency corresponding
to the band selected by the cursor. The cursor can also select the wide band level on the right side of
the display.
