Deviation Value Mark
The installation surface of the anode/heading adjusting
piece of the Lower casing unit is engraved with deviation
value marks, namely F, R and P respectively; Represents the
difference between the actual size and the theoretical size on the
casing of the Lower casing unit.
For example, the mark P is followed by +3, representing the
actual size which is 0.03 mm more than the theoretical size;
If there is no number after that deviation value, the value of P
is considered to be 0.
