Contact memory
determines what the pump will do when pulses are received while a
dose is in progress. If set to “ignore” the pulses will be forgotten by the pump. If set to
“add” any pulses received while dosing will be queued up in memory and will be
dispensed when the current dose has finished.
If pulses are buffered in the memory then the pump will not stop between doses.
