IGH LEVEL REFERENCE

[SPAN]

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].

f2.

Interface application

:

Press the flexure (59) against the adjusting screw shoulder (114) which corresponds to the highest specific gravity [HSG
CALIB]. While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays this
specific gravity.

g.

Slowly move the flexure (59) from one shoulder (114) to the other (slowly to avoid displacer oscillations) and verify the value
displayed. Correct adjustments if necessary.

h.

Reinstall all plugs (107), (190), and (115).
