# ACTA pulse strategy

To calculate the tool frequency, the ACTA Pulse Tool strategy uses a set of timers and recalculates the Cycle Start dynamically each time a peak is measured (the Cycle Start is set to the last peak value divided by 1.5).

The parameters that characterize the ACTA pulse strategy are:

- Measure delay time: when the torque goes over the cycle start value, the torque is ignored during this Measure delay time. This can be helpful to exclude noise and “false pulses” at the low torque values. The timeout can be set from 0 s up to 5 s. The default value is 0 s (no delay applied).

  Torque vs time

  A | Cycle start | B | Transducer full scale
  C | Measure delay time |  |

- Reset time: after each peak, the reset time defines a time during which the STa 6000 / STa 6000 Plus does not consider the torque trace. This can be helpful in order to avoid considering as two real peaks the real peak and the bounces possibly produced by the peak itself.

  Torque vs time

  A | Peak | B | Bounce
  C | Reset time |  |

  The value of this parameter depends on the frequency of the pulse tool and on the bounces possibly present in the trace. The timeout can be set from 0 s up to 5 s. The default value is 0 s (no reset time applied).

- End cycle time: when the torque goes and remains below the Cycle complete for the end cycle time, the test ends.
