You can set the properties of the peak program meters of the TFT displays with the aid of the Toolbox4 / Toolbox5 configuration software. Choose the according device in the project tree of the Toolbox, open the sub-branches of the "Logic System" entry and select "Level Detection".
Please enter the following values to emulate an analog peak program meter with an integration time of 10 ms, according to the standards DIN 45406 and IEC 268-10 (PPM, Type I), respectively:
Attack = 2 ms
Release = 0.7 s
Please use the following values to emulate a digital peak program meter:
Attack = 0 ms (or 1 ms if integration time is required)
