The instrument measures angular displacement from a reference, in this case the angle of the stones with respect to the vertical line that runs from the edge of the knife through the spine.
There are a number of different makes of inclinometers, but all should be able to be set/adjusted to zero. Using one on the stones/paddle gives an indication of balance in the set-up. We might assume the blade is vertical in the jaws, but should really check that first, as it is tightened. I simply use a square with folding knives, and check both sides of the handle when folded at 90 degrees to the blade, against the base. This gives a fairly good indication that the blade is vertical. Additionally the inclinometer can be held against both sides of the blade itself to check for an equal number. Make sure the base reads zero, or is level. Then of course the bevel can still be off it we don’t pay careful attention when stoning to keep the margin relatively equal. The WE does give the OCD a great opportunity to exercise itself.:lol:
