4.3.8 Position Adjustment Procedure of Pipette (“[11]p_tube 1)
Adjustment Parameter: Pipette Position XYZ
Summary: Use the sample tube with 50 µL of distilled water inside for the position adjustment of
the reaction tube rack.
Adjust 3 positions for each two separated reaction tube rack.
Standard:
XY direction: The center of each sample tube set into the adjustment position of the reaction tube
rack.
Z direction: The lowest point of the pipette descended to the sample tube, with 50 µL of the
distilled water inside, of each adjustment position of the reaction tube rack.
(1) XY Adjustment
1) Place 50 µL of distilled water into the reaction tube and set it into the tube No. 1 of the reaction tube
rack.

2) Verify that the “[11]p_tube 1” is shown on the left center of the screen. If not, change to “[11]p_tube
1” by using [Pos. -] and [Pos. +] keys.
3) Move the pipette to the setting position by using [XY TEST] key.
4) Use [n], [p], [m], and [Æ] keys to adjust the pipette tip to become the center of the reaction tube.

CAUTION: 1) Do not execute Z operation when XY adjustment is insufficient.
2) Be sure that the pipette tip is at the center of the reaction tube.
If not, it may cause the pipette to touch the reaction tube when descended.
