4.4 Calibration Using the LCD Setup Menu

The LCD Display option offers a menu driven setup that uses the UP, DOWN and SELECT pushbuttons. Refer to
the menu flow chart for navigation and selection instructions.

Setting the 4mA point:
-Under the CAL menu, scroll DOWN to the LRV (Lower Range Value) menu option. Press SELECT to
change the value (in Engineering Units) for which the 4mA point is to be set.

Setting the 20mA point:
-Under the CAL menu, scroll DOWN to the URV (Upper Range Value) menu option. Press SELECT to
change the value (in Engineering Units) for which the 20mA point is to be set.
Note: The above steps can be repeated as many times as required.
calibration for the selected Primary Variable.

4.5 Selecting a Primary Variable (PV)

This section applies to dual-float transmitters only.
For a dual-float transmitter, the primary variable (LL1 or LL2) defines the float used to calculate current (mA) output.
If the primary variable is set to LL1, current output will be determined by the position of the float nearest the
transmitter housing. Alternately, if PV is set to LL2, current will correlate to the float farthest from the transmitter.

Selecting the Primary Variable
-Under the SET menu, access the CFG menu, then go to the PV= menu option.
-Press SELECT, then press UP or DOWN to cycle between LL1 and LL2 (the LCD will be blinking with your
selection).
-When the LCD is displaying the intended selection, press SELECT once more to set PV (the display should
stop blinking).
Note: If the Primary Variable is changed, it may be necessary to reset the 4 and 20 mA calibration points.
