Re-calibrating Flow Sensors

Thermo Scientific
Two weeks after the last acknowledged solvent refresh, a solvents refresh due reminder button
is shown on the left menu panel
CAUTION You have to acknowledge a solvent refresh by clicking on the "Solvents
refresh due" or the "Solvents Refreshed" button. Otherwise the solvents refresh
reminder doesn't work properly.
Figure 48.
CAUTION
• Always refresh solvents A and B at the same time. Otherwise the solvent refresh
reminder doesn't work properly.
• If the solvent B composition has been changed during the solvent refresh, please
perform a flow sensor calibration.
Note A re-calibration of the flow sensors is recommended every 6 months and if
either solvent A or B composition has changed.
6 months after the last flow sensor calibration for flow sensors A and B, a "Flow sensor
calibration due" button appears on the left menu panel.
