d To align to the volume displayed, side D (or side B with multi-channel
pipettes) of the wrench is inserted horizontally through the calibration seal
into the alignment opening (Fig. 2-4) in the pipette grip. (When doing so,
hold the pipette vertically.) The wrench is then rotated into a vertical
position. The calibration seal is thereby destroyed and removed.
e
Research, adjustable-volume (variable) and multi-channel
When the setting ring is rotated (either in the + or - direction), the piston
stroke of the pipette is altered (although the volume-setting dial remains
unchanged).
One rotation is equal to the following:
Research, fixed-volume
To reduce the volume, turn the setting ring (Fig. 2-2) clockwise. To increase
the volume, turn the setting ring counterclockwise.
One rotation is equal to the following:
f Remove the wrench and move the setting ring backwards and forwards
until the counter and the stroke system lock together.
g Repeat step c). The readings must be within the tolerances specified in the
technical data.
Is the nominal volume does not correspond with the measuring result, repeat
steps d) and e).
