Page 21: Operating The Instrument
All digital settings of the 12400 instrument are made by means of three pushbuttons and a liquid crystal display on the front  of the instrument, or using HART communication handheld terminals or GE’s Masoneilan software: ValVue , ValVue AMS Snap-on and ValVue PRM .
Page 22: Pushbuttons Menus Description
6.1.4.4. FILTERING Menu (Appendix D) This menu allows the setting of the two filterings available in the instrument: ♦ Damping adjustment (analog filtering). ♦ Smart filtering parameters tuning. 20 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 23 6.1.4.5. 4-20mA GENERATOR Menu (Appendix E) This menu enables generation of a loop current to a defined value independently of true level measurement. This function is of help to set another instrument (such a positioner) in series in the loop, by generating the required output current. 6.1.4.6.

Page 25 c. Enter the BASIC SETUP menu to display [COUPLNG:%]. d. Look through the side orifice and verify that the screw (62) coupling end of the beam (54) is loose and that the spring arm (242) is disengaged from the pin (243). Through the 3/4 ” NPT hole at the bottom of the case, push the flexure (59) from left to right with your finger to verify it is possible to move the beam (54).

Page 27: Transmitter Calibration
7.3. TRANSMITTER CALIBRATION 7.3.1. O PERATING RULES AND CALIBRATION PRINCIPLE The purpose of this chapter is to detail internal device operating rules to understand names of functions and describe actions generated by the embedded firmware during calibration. Advanced settings are also described to answer user constraints. In some cases, the user can avoid doing a new calibration following a process change or can enable a level measurement on a specific range different than the standard one.
Page 28 The level indication corresponding to REF H is set through function [URV] via [VAR SET]; it is expressed in the unit set through [UNIT] function; if UNIT is "%", [URV] must be 100.00%. 26 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 29 ♦ Calibration of transmitter for interface application: The level transmitter is used to measure the interface level of two immiscible liquids of different specific gravities. The displacer must always be fully immersed. The electronic circuit is calibrated towards two reference levels (REF L and REF H). See schematic below. REF L corresponds to the displacer completely immersed in the liquid of Lower Specific Gravity used for calibration [LSG ...
Page 30 Enter and validate the [ZERO]: the [LEVEL:%] value indicated on the display must equal to 0.0%. If not, restart the procedure until very close to this value. See Appendix B. 28 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 31 d. High Level [SPAN] d1. Liquid application: Attach to the torque arm a set of weights equivalent to the apparent weight of the displacer fully immersed in the calibration fluid with Specific Gravity of Calibration [SG CALIB], i.e.: Displacer Apparent Weight for REF H = Displacer Actual Weight - (Displacer Actual Volume X [SG CALIB]) i.e.

See Appendix B h. Press the * button when [SAVE] is displayed to validate the [ZERO] and [SPAN] settings. 30 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 33: Calibration With Mechanical Stops
7.3.4. C ALIBRATION WITH MECHANICAL STOPS CAUTION: This procedure is only possible if mechanical stops (adjusting screws) have been previosuly adjusted upon process fluids. See mechanical stops setting Section 7.5. This calibration procedure is very useful on site and for interface application when there is no capability to make level variations into the tank.
Page 34 See Appendix B. h. Press the * button when [SAVE] is displayed to validate the [ZERO] and [SPAN] settings. Reinstall all plugs (107), (190), and (115). 32 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 35: Calibration Of Specific Gravity Meter
7.4. CALIBRATION OF SPECIFIC GRAVITY METER This adjustment is made at the factory for complete instruments. The specific gravity function [SG METER] is very useful in performing on site new calibrations, simulations with or without liquid and direct reading of specific gravity of liquids on the application.
Page 36: Mechanical Stops Setting
Press the flexure (59) against the adjusting screw shoulder (114), which corresponds to the lowest specific gravity [LSG CALIB]. While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays this specific gravity. 34 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Page 37 [SPAN] IGH LEVEL REFERENCE f1. Liquid application: Press the flexure (59) against the adjusting screw shoulder (114) which corresponds to the high level (on displacer side). While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays the value of process specific gravity [SG CALIB].

Page 43 7.7.3.2. Controller configuration Click either Direct or Reverse. Direct action means that the 4-20mA controller output increases when the process variable is greater than the setpoint when process variable (is Controller Action lower than setpoint for Reverse action). Click either PV or Error. This determines whether calculations are based on process variable Derivative Source or error.

9.4. MOUNTING OF DLT CASE AND TORQUE TUBE SUB-ASSEMBLY (FIGURE 24) CAUTION: The following procedure is valid only if the coupling between beam and torque rod has already been adjusted for the required mounting direction (see Section 7.1). The case mounting direction for which the coupling has been made may be identified as follows: When the case is mounted and coupled to the torque tube (without torque arm or displacer), the tip of the conical pin (53) is aligned with one side of the oval hole in the flexure (59).
