The values that it can monitor are the input source input level, the loudness level at a set loudness numeric value, target level, measured short time (average value of level integrated for 3-10 seconds)/medium time (average value of level for 30 seconds)/long time (average level for an entire program, commercial, or other content) 3-pattern color bar graph, and maximum loudness level, which can be displayed simultaneously. Furthermore, a histogram of the measured levels for 27 minutes to a maximum of 14 hours can be displayed.
Takashi Harada, a sales engineer for the SCA Sound Solution Company explains "This product also envisions use together with a VU meter and peak meter for master monitoring".
