Pulsar Nova® sound level meter user manual

Keypad and Controls
The Nova® is controlled via the four arrow keys (up, down, left and right), the center
select button and two soft keys, which change in function depending upon the mode that
the instrument is in. The soft key function is shown above the button on the display.
The left and right keys move between the Views and the up and down keys move
between the pages of each View.
The ambient light sensor on the front of the instrument will illuminate the elastomer
keypad and adjust the brightness of the display automatically when the light level falls.
If the instrument has the pause function and it has been activated (described on page
33), the right soft key toggles between pause and stop. Press once to pause/back erase
(if enabled – see page 37) and twice to stop, or alternatively press and hold for three
seconds to stop.
Switch on
The instrument is switched on by pressing and releasing the power button on the top
of the keypad. After the boot screen, your Nova® will display the last View that was
used.
If the start-up screen flashes quickly when you press the power button, the batteries
have insufficient power to start and they must be changed.
