25502020-03-24 00:00down by 1 mmCLOCKWISE by 100 units2738.67clock-wise also down in numbers; if that doesn't decrease silicon height, opposite move will be performed to match desired shift
25502020-03-25 00:00CLOCKWISE by 150 units from the bottomCLOCKWISE by 150 units from the bottom2551.97units from (2738.65-2550)/(2865.5-2738.67)*100=148, same direction as previuos move
     CLOCKWISE is defined from the bottom of the micrometer screw looking up. CLOCKWISE extends the rod of the micrometer screw which DECREASES the micrometer screw dial units. For the CLOCKWISE move silicon is moving UP.
