ABSTRACT:
A case for encasing a meter movement and its associated pointer comprised of an assembly at least a portion of which is transparent which completely encases the meter movement and pointer, connecting means for providing input signals to the meter movement through the assembly, a rear cover having openings for receiving the connecting means and proportioned to abut the rear of the assembly with the connecting means disposed within those openings, a scale of generally flat dimensions for displaying the parameter to be measured by the meter movement and indicated by the pointer which scale is held fixedly between the rear cover and the assembly in a position allowing a sweeping of the pointer across the face of the scale to indicate the level of the parameter sensed by the meter movement thereby allowing an exchange of the scale for some second scale without any possibility of physically engaging the pointer or the meter movement and causing damage thereto.
