ENGLISH
Low Threshold
Low Threshold determines where the shift between green and blue happens in the
outer ring. It indicates to the engineer that level is now at risk of being below the
noise floor.
True Peak Indicator
Sets the level at which the Peak indicator lights up.
OBS Indicator sets the conditions for the OBS indicator to light up. Turn it off, if you
don’t want warnings.
ALERT indicator
This is where you set the conditions for the ALERT indicator to light up. Turn it off, if
you don’t want warnings.
Time Reference
Time Reference can take two values: “Actual Computer Time” or “Program Time”. The
first is synchronized to the realtime clock of the computer, the latter to when a new
measure was started, i.e. when the “run” key was pressed. Note: The meter history
resets when you switch between Time Reference settings.
Radar Speed
controls how long time each radar revolution takes. Select from 1 minute to 24 hours.
You may “zoom” between the settings, as long as the history isn’t reset. Pressing the
“X” key, or changing the Time Reference, resets the meter and the Leq(M) readout
beleow the radar.
Radar Resolution
sets the difference in loudness between each concentric circle in the Radar between
3 and 12 dB. Choose low numbers when targeting a platform with a low dynamic
range tolerance. You may “zoom” between the settings, as long as the history isn’t
reset. Pressing the “X” key, or changing the Time Reference, resets the meter and the
Leq(M) readout beleow the radar.
