Abstract
An electronic measuring device includes a main printed circuit assembly and one or more channel modules. At least one channel module includes a channel printed circuit board and a first insulating housing that defines a cavity covering at least part of electrical elements mounted on the channel printed circuit board. A first conductive shielding frame is placed on the first insulating housing and is separated from the channel printed circuit board by the first insulating housing. The first conductive shielding frame covers the electrical elements mounted on the channel printed circuit board. A second insulating housing sandwiches the first conductive shielding frame between the second insulating housing and the first insulating housing which lengthens an electrical path from the first conductive shielding frame to the channel printed circuit board.
