Note:
We recommend to run and stabilize the unit before starting analyzes or
after a longer shutdown of the device at 1 ml/min, pressure 15-20 MPa for
approximately 30 min.
Note:
Run the gradient pump with a 25 % concentration setting for each valve
approximately 10 min.

Abbreviation of actual pump mode.
Actual piston position is displayed after first finished pump rotation.
During flowrate higher than ~3 ml/min actual position cannot be displayed

Pulsation compensation status:
OFF
– turned off.
FIXED
– according to predefined values.
LEARNING
– learning in progress.
LEARNED
– according to learned values.
LEARNED OFF
– compensation is turned off.
LEARNED 0
– according to learned values (from FW 5.x).
LEARNED 0
– compensation is turned off or not learned (from FW 5.x).

Gradient valve status (A, B, C, D). Only in gradient mode. During very fast
valve switching (low percentage of component and higher flowrate) it may
not manage to display valve switching.
Mark X
– all valves are closed.
