To verify the plumbing path
1. With both the Point-to-Plumb window and the front of the instrument in view,
click a segment of the gray path in the Point-to-Plumb window.
The segment you selected turns green to indicate the correct plumbing path.
At the same time, green LED lights flash on the front of the instrument,
indicating the ports to be connected to each other.
2. Check the instrument plumbing and the Point-to-Plumb display to verify that
the selected segment of the plumbing is correct. If it is not correct, replumb it.
3. Continue selecting segments of the plumbing path and verifying that they are
correct.
4. When you have finished verifying the plumbing path, click Exit Point-to-Plumb.
The LEDs on the instrument turn on. Depending on the module, LEDs indicate
 Flow from the system pumps (green LEDs)
 Flow from the sample pump (blue LEDs)
