BACK LIGHT - This key turns on the LCD back light for easier viewing of the display in a dimly lighted area. The back light is activated by pressing the key and is deactivated by again pressing the key.

NOTE

The back light consumes significant power. To extend battery life, use the back light only when needed.

TRANS. VAR'S. - The Transmitter Variables key is a quick access key that is pressed to display a screen showing the transmitter's on-line parameters: measured variable (MV), current output (I), process variable (PV) and their respective units. Exit this screen by again pressing the TRANS. VAR'S. key or by pressing the F4 key, for END. If the transmitter is configured as a transmitter-controller you will be prompted to choose either transmitter variables or controller variables. Controller variables include process variable, setpoint and valve.

TREND - The TREND key is another quick access key that is pressed to trend a variable and show up to thirteen samples. Any one of the following variables can be trended: the measured variable (MV), the current output (I), or the process variable (PV). The trend sampling rate can be set to 1-300 seconds between samples. Exit this screen by again pressing the TREND key or by pressing the F4 key, for END.

ZOOM - The ZOOM key is a quick access key that allows a closer examination of a variable chosen in the Trend screen. This key functions only when a Trend screen is displayed.

ZOOM magnifies a range of values equal to 10% of the span. The midscale value is user selected. For example, when viewing a range of 0-100% in the Trend screen, the value of 50% is chosen to zoom on. The Trend screen now shows a range of 45-55%. Exiting the Zoom screen again displays the Trend screen. Exit the Trend screen to return to the Main Menu.

STATUS - The STATUS key is a quick access key that is pressed to display the Status screen. This screen will show the instrument tag name, model number, software revision number, serial number, and functional statuses such as fixed current mode and error conditions. Exit the Status Screen by again pressing the Status key or by pressing the F4 key.

CHANGE SP, CHANGE VALVE, A/M, and TUNE Keys - These are dedicated keys that are reserved for use with XTC Model 340 and 344 Transmitter-Controllers. These keys are inactive when communicating with an instrument that does not have a controller function block.

CHANGE SETPOINT - Press the CHANGE SP key to view and change the value of the online- setpoint of the controller in either automatic or manual mode. If the controller is in MANUAL with tracking setpoint, then the setpoint cannot be changed. The SP is displayed in the same units as the transmitter display configured in the operator’s display function block. Press the “CHANGE SP” key again, or F3, to exit this mode.

CHANGE VALVE - This key allows you to view and change the position of the valve. If the controller is in AUTO, the valve cannot be changed. Press the “CHANGE VALVE” key again, or F3, to exit this mode.
