c. Place the caps on the sample containers. After checking that the
white side of the septum faces up, tighten each cap loosely.
Overtightening the caps may twist the septa, making them
unusable.
3. Load the sample containers into the sample rack and/or standards
rack in the order required for the application.
3.2.2 Turning On the Power
1. Turn on the AS-HV main power switch.
At power-up, the AS-HV automatically begins an initialization
sequence in which the sampling needle moves through the extent of
the autosampler’s working envelope. Upon completing the
initialization sequence, the needle returns to the home position above
the fixed rinse reservoir. During initialization (see
Figure 3-1 ):
•
The needle raises to the full extremes of the Z-axis.
•
The needle travels to the full extremes of the X-axis.
•
The needle travels to the full extremes of the Theta-axis.
If the sampling needle fails to initialize successfully, refer to
Section 4.3 for troubleshooting assistance.
