TABLE 3-1. LOI Data Entry Keys and Functions
Data Entry Keys Function Performed
Shift • Moves the blinking cursor on the display one character to the right.
• Scrolls through available values
Increment • Increments the character over the cursor by one
• Steps through all the digits, letters, and symbols that are applicable to the present operation
• Scrolls through available values
Enter Stores the displayed value previously selected with the SHIFT and INCR. keys
Display Control Keys Function Performed
Flow Rate Displays the user-selected parameters for flow indication
Totalize Displays the present totalized output of the transmitter, and activates the Totalizer group of keys
The choices, Forward and Reverse totals or Net and Gross totals, are selected in Auxiliary Functions
Totalizer Keys Function Performed
Start/Stop Starts the totalizing display if it is stopped, and stops the display if it is running
Read/Reset Resets the net totalizing display to zero if it is stopped, and halts the display if the display is running
Transmitter Parameters

Function Performed
Tube Calibration Number Identifies the calibration number when using Rosemount flowtubes, or other manufacturers’ flowtubes calibrated at the
Rosemount factory
Tube Size Specifies the flowtube size and identifies the corresponding maximum flow (0.15- through 60-inch line sizes)
Units Specifies the desired units:
Gal/Min Liters/Min

Transmitter Calibration
Analog Output Range Sets the desired 20 mA point – must set the tube size first
Pulse Output Scaling Sets one pulse to a selectable number of volume units – must set the tube size first
Damping Sets response time (single pole time constant), in seconds, to a step change in flow rate
