5.2 MotorPositioningGuidelines
When settingup theSampleTray and Injection Inlet positions the arrowkeys act as adirectional
input for axismovement (Left /Right arrowkeys forLeft /Rightmovement and theUp /Down
arrowkeys for Front / Rearmovement). Thismovement is achievedwhen the operator
"taps"
or
pushes adirectional arrowkeymomentarily. If themovement is not "fine" enough, the step ratemay
be changed from "Continuous" to "Jog", and thenumber of steps permovementmaybe changed.
To access thismenu, from the "Target CoordinateSetup"menu,move the head to a target and then
press the "Mode" key. The "Select:"menu comes up, fromhere, the type ofmovement, either Jogor
Continuousmaybe set, also thenumber of steps permovement. Changes aremadebypressing the
"Mode" key or the arrow keys. The default step rate is factory set at 10. To exit themenu press the
Stop key.

the "Vertical"menu line andwith theRight arrowkey, lower the syringe arm to just above thevial
cap. Install the syringe andmake the final adjustments to theneedleposition.
Theneedlemust be
positioneddown into the vial tonot hit the bottom!.
After the setup is completewrite down the
number coordinates for future use.
Press theEnter key and the armwillmove tohome, toggle to thenextmenu line "Waste", press
Enter. The sameX-Y-Z coordinatesmust nowbe established for theWaste (1&2) and forRinse (1
&2) and for the injection InletsA&B. Theprocedure for these settings is the same as for Sample
#1. Theonlydifference is the inletswill requirea finer adjustment than thevials. Onceall thecoordi-
nateshavebeenestablished install the syringeand recheck the target locations.
