TouchMonitor Help | Display Mode - Loudness Numeric Instrument

In display mode, the TouchMonitor shows the instruments and their layout defined in the currently loaded preset.

Touching the screen area of an instrument will put this instrument into focus. This is recognized by a colored frame instead of a grey one. The frame color conforms to the identifier set for the group the focused instrument belongs to.

The Control Bar positioned at the lower screen edge contains several keys. It is displayed permanently if the "Control Bar" option in the "General" section of the "System" menu is set to "permanent". Otherwise, it will be displayed temporarily after touching the screen.

The Control Bar has two sections. The left (upper) section shows the specific keys defined for the focused instrument. This makes it very fast to access a specific function of one of the instruments on screen – just touch the instrument and select the desired function.
The right (lower) section shows general keys.

The specific keys that are displayed in the left (upper) Control Bar section can be defined individually for each instrument. To do this, touch the "Edit Instrument" key and select the "Configure Keys" option in the menu. The default value for each key can be set in the menu as well.

The Loudness Numeric instrument (Loud. Num.) is only available after one of the loudness modes or custom was selected for the audio group the instrument is in. According to selected standard or to the customer specific settings it displays the numerical readout of the running loudness measurements and maximum values.

•	M (Momentary):	Summed momentary loudness measurements of the individual channels using an integration time of 400 ms.
•	S (Shortterm):	Summed loudness measurement using an integration time of 3 s and a sliding window.
•	I (Integrated):	Overall program loudness between start and end points that are entered manually. Use the Start, Stop and Reset buttons to execute this measurement.
•	LRA:	Loudness Range
•	TPmax:	The highest measured True Peak value in dBFS
•	Mmax:	The highest measured Momentary value
•	Smax:	The highest measured Shortterm value
•	Itime:	Duration of the Integrated measurement

If needed, the numerical readouts of these individual loudness measurements can be activated or disabled individually. The values of current running measurements for I, LRA, TPmax, Mmax, Smax, and Itime values will be colored green, those of stopped measurements yellow. If values are exceeding the upper limits, they will be colored red.

With the Loudness Numeric instrument in focus, the left (upper) section of the Control Bar may contain any or all of the keys described below.
