Checking Position Alignment

The 215 Setup Utility (Adjust XY tab), described in Section 3, allows you to test whether the liquid handler is properly aligned and to make minor adjustments to the X-axis and Y-axis offsets if needed. You may need to use the options under this tab if the probe is not accessing the injection port of the injection module installed or the vessels in the installed racks. This tab is described below.

The X offset and Y offset text boxes display the current offsets stored in the instrument’s memory.

To determine if the probe(s) need(s) to be adjusted in the X- or Y-direction select the model of the injection module that is on your Quad-Z (probably an 849) or select other for a user-defined test point. The default XY coordinates are shown next to the model number below.

model 819: X-coordinate: 544.0 mm Y-coordinate: 3.8 mm

If the model 819 is not installed next to the right support use the following coordinates: X-coordinate: 351.1 mm

Y-coordinate: 1.3 mm

model 841: X-coordinate: 475.3 mm Y-coordinate: 3.8 mm

model 889: X-coordinate: 336.1 mm Y-coordinate: 3.8 mm

model 849: X-coordinate: 336.1 mm Y-coordinate: 3.8 mm
