Section 4.0 Display and Operation

4.1User Interface

The T56 has a large display which shows two live measurement readouts in large digits and up to six additional process variables or diag- nostic parameters concurrently. The display is back-lit and the format can be customized to meet user requirements. The ENTER/MENU key allows access to Calibration, Hold (of current outputs), Programming, Display, Data and HART functions. In addition, a dedicated INFO key is available to provide access to useful diagnostic and instrument information regarding installed sensor(s) and any problem- atic conditions. The display flashes a red banner to indicate a Fault condition and a yellow banner for a Warning condition. Help screens are displayed for fault and warning

conditions to guide the user in troubleshooting. During calibration and programming, key presses guide the user step-by-step through procedures. An alpha-numeric keypad similar to a cell phone keypad is available to allow the user to enter data during programming and calibration or lengthy tags to describe process points, sensors, or instrumentation.

4.2Instrument Keypad

There are three Function keys, four Navigation keys and an alpha-numeric keypad on the instrument keypad.
