The pressure setpoints. The red line shows the current maximum pressure limit; the gray area shows the current pressure (also shown as text).

The current solvent flow rate (in mL/min) is displayed above the pressure display.

Instrument Signals

The instrument signals are displayed when clicking the icon in the upper right corner of the module dashboard. The following pump signals are displayed:

Flow	The current solvent flow rate (in mL/min).
Pressure	The current pump pressure (in bar, psi or MPa, see Instrument Configuration).
Tuning	Indicates the tuning efforts of the pump. For pumps operating as expected, the signal should stay in a range of –1 to +1 within the full-scale of –2 to +2.
Pressure Limit	The current maximum pressure limit.
Composition A:B	The contributions of channels A and B to the current solvent composition.
Composition C:D	The contributions of channels C and D to the current solvent composition.
