• Running a measurement
• USB communications
Pressing the 0 (ON / OFF) key will return the instrument and the
display to the state it was in when the Auto-Off time expired.
In the power save mode, battery power will significantly reduce by
shutting down the analog circuitry and the signal processing
activities.This feature is designed to shut down all data collecting
processing to save on battery.
The analog power-save time is the duration of time the instrument will
stay fully powered after a measurement has stopped. The analog
circuitry, including power to the preamplifier will shut down when the
instrument has been stopped for the time set. Starting a measurement
or performing a reset will restore power to the analog circuitry and the
instrument can run the measurement after a ten second delay.
Performing a calibration will also restart the analog power-save time.
Backlights-On is the duration the SoundAdvisor display will be back lit
after the last key press. Selecting Always on will increase power
consumption.
