(3) Pipette Lower Limit Adjustment
When [FIX] key is pressed to complete adjustment, 25 pulses are added to Z pulse setting value and the value

Large value should be set as the pipette lower limit when executing Z adjustment so that the probe can seek a
liquid surface at the lowest point. Be sure to set water inside the tube when setting large value manually as Z
pulse. If not, it may cause the pipette to crash at the bottom of the tube or the motor to be mis-adjusted by the
pulse beyond the limit.

displayed and manual change is available.
