6. Use the
arrow down and arrow up keys to
navigate to the current value of the cut-off
frequency for the rate of turn (RoT) low-pass filter. The same applies to the cut-off
frequency for the low-pass filters for the roll and pitch rates.
A small value of the cut-off frequency denotes high damping while a large value
means low damping.
Often, the term damping time constant is used instead of cut-off frequency: The time
constant is the reciprocal value of the product of 2ꞏπ and the cut-off frequency.
‐
The selected value will be highlighted yellow.
If Standard 30 MF is used in combination with Standard 22, then, the
cut-off frequency value for the rate of turn (RoT) low-pass filter needs
to be set to 0.2 Hz in order to harmonize the RoT damping of both
compass types at the analog output of the Distribution Unit, type 138-
118.NG002 or 138-118.NG003.
7. Press the
Set
key to confirm the selected value.
‐
The font color of the chosen damp value setting changes to orange.
The lower the adjusted frequency value the smoother the output
behavior.
8.
Use the
arrow down and arrow up keys to set the desired value.
‐
The displayed value is incremented or decremented by 0.05 Hz with each press of
the key.
9. Press the
Set
key to confirm the entered value.
