bars), or less than –100 psi (–689.5 kPa or –6.68 bars), contact Waters
Technical Service.

output of the pressure transducer. Once you exit the Calibration menu,
the displayed pressure reading shows 0 (zero) to reflect the setting of the
0 Pressure parameter. If your pump is connected to an external control
device, setting the 0 Pressure parameter does not affect the pressure
reading displayed at the external device.
