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). The value displayed should vary accordingly. Pin (72) must rotate freely inside the coupling end of the beam.
Look at the mechanism through the lateral orifice, and index the oval hole of the flexure towards the special conical ended pin (53) by bending the flexure (59) toward the case front (see Figure 15). The value read on the LCD must be between –5% and +5%.
