Hinged, Dual Compartments The LCD module compartment houses the user interface and the lower compartment houses the wiring terminals. A screw release allows the LCD compartment to swing completely clear of the wiring module. Plug-In Display Module The module offers easy set-up and config- uration of all process parameters via four push buttons. The custom graphics LCD displays six-characters and a bar graph of signal strength or tank level. The module can be removed to configure other 335 units. 335 Electronics Advanced digital signal processing provides optimum performance in a variety of process conditions.
