EU – Engineering Units Meter
The Engineering Units Meter (EU) is described briefly here only in the context of RMA 3000 application
and installation. For detailed information such as digital display features, installation, set up and operation,
refer to
34-ST-25-18 Engineering Unit Meter User's Guide.
Function - The Engineering Unit Meter is an LCD indicator that provides a digital display of a
transmitter's output PV when connected in a 4 to 20 mA analog loop. The meter is compatible with
Honeywell SmartLine transmitters operating in analog mode and with other non-Honeywell transmitters
operating in a 4 to 20 mA current loop.
Description - The EU meter is designed to provide a simple indication of a transmitter's output value. A
multi-segmented LCD display is encased in a circular black plastic frame for local installation to the
transmitter. A printed circuit assembly (PWA) is mounted behind the display and contains the electronics
and wire connections for the meter. The EU meter is powered from the transmitter loop current. A
momentary contact toggle switch is mounted on the PWA and is used for setting up and verifying the
display indication.
