Adjusting Illumina struts.

On the Illumina struts, the adjustment dial that comes with them has a line through the center, and 2 dots to sides at one end of the line. My question is, what end of the line am I lining up to the numbers? One end points to numbers, and the other in between. The instructions don't show or mention anything about it, and I don't want to screw them up by running them in between settings. Thanks for any help.

the line should be lined up with the number and the dots should be on either side of the number.

Thx. That's where I have them, but was just going by feel and wanted to make sure.Again, thx.
