LM5 & LM5D -TDM / 9 E E N N G G L L I I S S H H not to measure programs of a shorter duration than approximately 10 seconds, while the maximum duration may be 24 hours or longer . Before a new measurement, press the “X” (Reset) key . This resets the descriptors, the radar and the true-peak meters.
PPM P AGE Press the “PPM” key to bring up the PPM display , Fig 6. The PPM page is used to inspect balance between channels, headroom, overload of channels etc. Fig 6, PPM T rue-peak meter features. Bargraph PPM meters are shown next to the round Current Loudness display , which is identical to the Outer Ring of the Radar page.
PREFERENCES P AGE Fig 8, LM5 Prefs page. Preferences may be stored as Presets, thereby having suitable settings for different conditions easily at hand. Loudness Scale can be set to either “Loudness Units, LU” or “Loudness Full Scale, LFS”. Because LM5 uses the BS.
