Filter
Undesirable signal fluctuations can be suppressed through the adjustable filter in the
parameter td “Filter time constant” (see Fig. 6.1, Table 7.1).
The filter time constant can be set within the range 0…10 seconds. The higher the value, the
slower the display reaction to changes of the input signal and the lower the susceptibility to
interference. The filter is deactivated if td = 0.
