d with the result of the measurement, repeat points 2 5.
  • After adjustment, check the accuracy of the measured values of the nominal volume and of 50% of the nominal volume.
  • 8.2 Adjusting pipettes (fixed-volume)

    Fixed-volume pipettes are adjusted in the same way as adjustable-volume pipettes (with fixed-volume pipettes,
    10 measured values of the nominal volume are checked).

    Adjusting the Series 2000 (Reference),
    fixed-volume:
    To facilitate relocation of the initial setting, attach the label provided (calibration aid) to the control button, as described in the instruction manual.
    Using side B of the universal tool provided, loosen the inner screw until the control button can be rotated (see Fig. 1). Adjust the control button to the volume which has been obtained under point 4 (see instruction manual). One revolution of the control button is equivalent to the following (figures based on water):
