Measured with the Optical Level the vertical distance from the TestStand Stage0 Supports to the top of the Optical Table.  This gives us an idea of how tall the assembly is wrt design.

Using the Wilde Optical Level we averaged the four ends of the HAM Adapter Bars Height.  These sit between the Stage0 bottom and the Test Stand.  This gave us an average height of the bottom of the Stage0 mount.  We then shot the top of the Optical Table at four corners and the middle.

The average height difference was 780.8mm; the design height given by DCoyne PerComm is 780mm.

So not bad.  Attached is the field note.
