Measurement device

A measurement device for measuring whether a distance between a center of a through hole defined in a panel and a side of the panel extending from an end of the panel meets a determined specification, the device comprising:

• a support member;
• a positioning member set on a first end of the support member, and comprising an inside surface to resist the side of the panel;
• and
• a measurement member set on a second end opposite to the first end of the support member, wherein a distance between the inside surface of the positioning member and a center of the measurement member is substantially equal to a normal distance between the center of the through hole and the side, wherein the measurement member is operable to enter into the through hole in response to an actual distance between the center of the through hole and the side about equal to the normal distance, the measurement member cannot enter into the through hole in response to the actual distance between the center of the through hole and the side unequal to the normal distance.
