ABSTRACT:
A panel meter having a unique casing with an adapter on the casing. The meter movement is in a compartment of the casing and the adapter is secured to the casing and cooperates with the casing to define a compartment separate from the meter compartment. Components such as calibrating resistors and rectifiers can be installed, if required, in the separate compartment after the meter movement is installed in the casing. In the preferred embodiment, the casing has a configuration generally in the form of a segment of a cylinder, and the adapter has a segment configuration so that the casing and adapter present a generally cylindrical profile when joined. This arrangement permits using the same basic meter movement and casing to produce meters of different operating characteristics. The meter either with or without the adapter can be inserted through the usual circular opening of a mounting panel. The casing has toothed sides to retain a quick connect panel nut used to secure the meter to the panel.
