Aligning
Input Stack 1
(Zymark Position 4)
The alignment of input stack 1 (position 4 in the Zymark Twister Software) is the first
step in the alignment procedure. This alignment provides the basis for aligning all
subsequent stacks on the plate handler.
To align the input stack 1 (Zymark position 4):
Step Action
1 Place an empty plate into input stack 1(Zymark position 4).
2 From the Zymark Twister Software, click position 4.
Click
The plate handler arm moves over the input stack.
3 Using the Vertical Positioning commands, lower the plate handler arm until it is just
above the stack.
The Vertical Positioning box offers four ways to move the plate handler arm:
♦ Move the slider for large increments.
♦ Click inside the slider bar to move the arm in 250 step increments.
♦ Click the lower arrow on the bar to move the arm in 50 step increments.
♦ Click the up or down arrows in the Vertical Adjustment text box to move the arm
in 1 step increments.
♦ Click the Vertical Adjustment text box, type a value, and press Enter to move the
arm into a specific location.
Slider
Slider bar (250 steps per click)

♦ is centered over the stack
♦ will not contact the sides of the stack when lowered
