ADJUSTMENT

Adjustment is done only for one volume. The recommended
adjustment volume is the minimum volume or 10% of the maximum
volume. Multichannel pipettes adjustment check prior calibration
is done using one of the middle channels.
1. Place the service tool into the openings of the calibration nut at
the top of the handle.
2. Turn the service tool clockwise to increase, or counterclockwise
to decrease the volume.
3. After adjustment check the calibration according to the
instructions above.
