6.4.5Optimizing the systemAfter defining the sensor-specific parameters, additional parameters can be set according to use.The following shows how to set Pulse Output A and Qmax.For other parameters, refer to "Parameter lists (Page 69).Setting Pulse Output and Maximum Flow (Qmax)1. Navigate to menu "Device" → "Pulse guide"The "guide" calculates the pulse-frequency at the max flow condition and tells you how close you are on over-speeding the pulse-output. The volume per pulse is freely scalable from 0.000001 to 10000 units per pulse. It also calculates the minimum volume per pulse you can choose to avoid pulse over-speeding. The maximum output frequency depends on the pulse selected; e.g. maximum output frequency at 5 ms is 100 Hz. Increasing the pulse width lowers the maximum output frequency.2. Select maximum flow rate (never to be exceeded).3. Select an appropriate pulse width, e.g. 5 ms.
