Trace | Multi Trace Operating Instructions
Operation
8.3.9 Menu “Controller”
The integrated controllers (PID Controller and
Minimum-Maximum Controller) can be
configured and operated in the menu
“Controller”. The controllers can directly drive
external pumps (via the serial interface or analog
output 3 on the back of the device) as feeding
pumps.
For BioPAT
®
Multi Trace the controller is also
available, but only in single-channel operation.
Ifseveral test ports are measured, the controller
may not be used, since the respective last signal
(no matter what test port) is used for the
controller as an input variable, thus resulting
faulty feedings.
On the display a box with the indication of the
current feed rate (0–100%) of the feeding pump
appears when the pump is active.
A green background indicates an active
controller.
The background turns red when the controller
isinactive.
The respective feed rates are recorded in the
bpd-file (see Chapter 8.2.1).
