PUMP CALIBRATION

Pump calibration will increase the accuracy of
the various displayed flow rates and volumes. In
Single-Point Calibration (see first diagram below),
the pump is calibrated to a specific stroke length
and flow rate (P1), changing the slope of the flow
line as indicated in the diagram. The "Calibration
Region" extends to +/- 10% of the calibrated stroke
length. As a result, the Single-Point Calibration
should only be used if the stroke-length is to be
maintained within 10% of the calibration setting.
In Two-Point Calibration (see second diagram
below), the pump is calibrated to two specific
stroke length and flow rate combinations (Pa and
Pb), changing the slope and the offset of the flow
line as indicated in the diagram. Pa and Pb stroke
lengths must differ by at least 10%. The "Calibration
Region" extends from -10% of Pa to +10% of Pb
stroke lengths. The Two-Point Calibration will
always result in a larger "Calibration Region" than
the Single-Point Calibration.
When a pump has been calibrated, the
is displayed in the Icon/Alarm area of the display
(see Sec. 4.5). If the stroke length is adjusted
outside the calibration region, the
be displayed in the Icon/Alarm area of the display.

Use the UP or
desired calibration mode. Use the
button to select the mode (see Sec. 6.6.1 for
single-point calibration procedure or Sec. 6.6.2 for
two-point calibration procedure). Use the
