Digital Filtering
The digital panel meters are extremely fast to follow the trend of input signals and
to display the relevant values. Unlike in analog panel meters, which tend to filter
the input and present a more stable indication, the fluctuations in digital panel
meters can be quite fast and prevent the user from clearly reading the displayed
value. Fluctuations can also be introduced when the resolution of the displayed
value is higher than the input resolution. The use of a digital filter results in
higher stability of the displayed value.
There are two types of filter parameters.
The first is and it defines the operating range of the filter. Generally,
Fil.S represents the resolution (in digits) wanted to assign to the display. It is
suggested to set this parameter to evaluate the amplitude of the fluctuation on
the display and use this value as Fil.S. If, for example, a display value fluctuates
between 2.5 and 3.4, it means that the fluctuation is 9 digits and the Fil.S must
be set as “9”.
When is displayed, you may elect to program filter values by pressing the
key. This results in being displayed. Using the key, toggle to
the desired position and select the value to enter by using the keys. Press
to confirm and advance to the next step in the sequence.
