Abstract
Since a dial face (3) and an area indicator (4) are formed separately to be independently turnable, the area indicator (4) is not rotated even when the dial face (3) is rotated. With this arrangement, the area indicator (4) can indicate a correct area regardless of the rotated position of the dial face (3), thereby preventing measurement errors. Further, since the area indicator (4) is not included in the dial face (3), the dial face (3) can be shared as a standard dial face.
