For other level measurement options, see Chapter 5.21, "Level Measurements" ,
on page 359, and Chapter 5.36, "Level Monitor" , on page 456.
Input Monitor
Used to activate the input level meter and to select the measurement method.
"Off" The "Input Monitor " is switched off.
"Peak" The peak input value is measured. The numerically highest input
sample is determined within a preset interval.
Note: In contrast to peak measurement, which – like all measuring
functions – takes place downstream of the filters, no interpolation fil-
ter (oversampling filter) is used.
Remote command:

5.36 Level Monitor
The level monitor is a level meter which is used to determine the level downstream of
the prefilter but upstream of the function-specific digital filters.
For other level measurement options, see Chapter 5.21, "Level Measurements" ,
on page 359 and Chapter 5.35, "Input Monitor" , on page 455.
The level monitor works with period detection and measures the input signal – starting
at the zero crossing – across a complete period, but at least with 100
samples. With
function measurements with extremely short measuring times (e.g. peak measurement
with 1
ms interval time), the level monitor should therefore be switched off.
Level Monitor
Used to activate the level monitor and to select the measurement method.
"Off" The level monitor is deactivated.
