Tecan Fluent PULSE

Can someone tell me what is the Tecan Fluent Control (version 3.4) PULSE volume? Searching “Pulse” on the Tecan help documents leads to PWM (pulse width modulation).

PWM I understand
Pulse volume and how it relates to pipetting accuracy & precision… I do not.

The pulse volume simulates how the liquid in AirFCA moves.

This is critical for multi-dispenses <25uL

I have some more detailed information, but would have to retrieve it from my notes.
