Remedial Action
(where x specifies if left or right flow sensor)
Wait until the module is equilibrated and repeat the autozero.
(where x is the exact deviation from the zero position.)
Turn the module off and on again by pressing the power switch on
the rear of the module. If the message appears more often, contact
Service.
During solvent calibration with the ProFlow flow meter, air bubbles
were detected in the flow path. Purge the pump (→ page 72).
You tried to move the pistons of the loading pump into the position
for piston or piston seal replacement although the flow rate was not
yet down to zero.
Set the pump flow rate to 0. Wait until the system pressure is down to
zero.
