 ''Hidden/fixed: ''Hidden if Mode is Trigger.
-* '''Missing teeth:''' This setting indicates the number of possible consecutive missing teeth (no pulses). In such case depending on the active mode:
+* '''Missing teeth:'''  ''Torsional:'' : [[NVGate_Torsional|read Torsion page]]
-* ''Torsional:'' the system interpolates the missing pulses intervals in order to maintain the instantaneous speed at a continuous level during the missing pulses.
-OROS torsional function is able to manage fractional pulses. It offers to achieve torsional measurement on the field in a simple and easy way.

-The empty area (missing teeth) length at the piano tape junction must be included between 1 and 3 teeth. The number of missing teeth must be set to the exact number of missing teeth: In this example: 2.
-Note: the total number of teeth includes the missing teeth.

-'''Attention''': The time lap of the first missing pulse must be longer than twice the time lap of the previous pulse interval
-'''It is recommended to set the instrumentation in order to limit the number of missing pulse below 3s''': Indeed long interval without pulses will lead to a strong order 1 artefact in the instantaneous speed signal due to interpolation of sample. Remaining below 3 missing pulse provide correct measurements
 * ''Tach:'' the system uses the missing teeth occurrence as the phase reference.
