excellent accuracy and precision.
The accuracy and precision (repeatability) of liquid vol-
ume depend on the quality of tips used. The values for
accuracy and precision given in the table below were
obtained using A.B.T. tips.

The accuracy and precision are obtained, using a gravi-
metric method, performing at least 10 measurements of
distilled water at a temperature of 20±1°C, according to
EN ISO 8655 standard.
The pipette design enables the user to perform the
recali bration process according to the rules presented in
section 8.

2 - SETTING THE VOLUME
The counter displays three figures to be read from top to
bottom. Additional to the figures on the lower wheel are
printed graduations to enable a volume setting in the
range increment of each pipette model.

The volume of the pipette is set by the knob in the pipet-
ting pushbutton (Fig. 1A2) or by the black adjustment
knob (Fig. 1B). To attain the maximum accuracy, set
volume must be approached from a higher value by
diminishing counter readings.
