The 375 Field Communicator provides universal HART support in a single intrinsically safe handheld communicator. Functions performed by the 375 Field Communicator include configuration of all FOUNDATION fieldbus devices, diagnosis for effective start-up and troubleshooting of FOUNDATION fieldbus segments, creating a quality segment by diagnosing network DC voltage and average noise, detecting power supply problems by monitoring low frequency noise on a segment and locating incorrect terminations and faulty devices by diagnosing the communications signal level. With many different HART and FOUNDATION fieldbus devices available from more than 100 different vendors, having a single field communicator with universal compatibility is an ideal situation.

The large display employs transflective technology, making it easy to read in bright sunlight and normal lighting as well as a multi-level backlight for dim conditions. The touch sensitive screen and large physical navigation buttons provide for efficient use both on the bench and in the field. Weight is distributed for comfortable one-handed operation in the field.
