Digital multimeter having hinged shield arrangement
First Claim
1. A multimeter comprising:
- a case having a user interface and a display, said case defining an interior cavity;
a circuit board located in said interior cavity of said case, said circuit board having a top side and a bottom side;
a shield arrangement located in said interior cavity of said case, said shield arrangement configured to cover at least a portion of said top side and said bottom side of said circuit board so as to reduce effects of interference on operation of said multimeter;
said shield arrangement including a top shield part adjacent to said top side of said circuit board and a bottom shield part adjacent to said bottom side of said circuit board; and
said shield arrangement further including a connecting structure by which said top shield part is interconnected with said bottom shield part;
wherein said connecting structure forms at least one hinge configured such that said top shield part and said bottom shield part can be moved between open and closed configurations.

Abstract
A multimeter comprises a case having a circuit board located therein. The circuit board has a top side and a bottom side. A shield arrangement is configured to cover at least a portion of the top side and the bottom side of the circuit board. The shield arrangement includes a top shield part adjacent to the top side of the circuit board and a bottom shield part adjacent to the bottom side of the circuit board. The shield arrangement also includes a connecting structure by which the top shield part is interconnected with the bottom shield part. The connecting structure preferably forms at least one hinge configured such that the top shield part and the bottom shield part can be moved between open and closed configurations. Often, a plurality of hinges will be provided.
