"Parameter set" "Small"/"Large"/
"Custom"/"Flow"
Setting the control response
– "Flow": Designed for flow rate applications.
Quieter control response thanks to greater hys-
teresis. Can also be used for closed volumes.
– "Small": Standard set for all applications.
Optimised for closed volumes of
100mltoapprox.750ml. For larger volumes,
"Small" results in a gentler control response
than "Large". For applications with flow rate,
"Small" is only suitable to a limited extent (<
100l/min)
– "Large": Optimised for closed volumes
(³750ml on 1m tubing, Æ8mm). Faster
adjustment of pressure jumps.
– "Custom": Individual adaptation to larger
volumes or applications with longer/thinner
tubing or constrictions within the application.
"Reference run" "Start" Appears only if "Parameter set" = "Custom".
"Tune pres incr" E.g.5200 "Tuning pressure increase" appears only if "Para-
meter set" = "Custom".
Setting of the tuning parameter for pressure jumps
upwards.
