optimus sound level meter user manual
Page 18
An AC output is available on the optimus via the 3.5mm jack socket. The output is un-
weighted and the output level can be adjusted using the options in the AC Out menu.
This output can be used with external instrumentation. See page 37 for details of the
electrical outputs.
Screen saver
If no keys are pressed for 6 minutes the display will dim to preserve battery and
screen life, and reduce power consumption. After 30 minutes with no key presses the
display will switch off completely and keypad flashes every two seconds to show that
the instrument is powered. The screen dim and screen saver functions will occur
during measurements as well as when not measuring. Press any key to restore the
display.
The time intervals for the screen dim and screen saver are configurable in NoiseTools.
Display
The optimus uses a high resolution colour OLED screen to show a clear and easy to
read display of all the information you need.
