7.5. MECHANICAL STOPS SETTING

This procedure consists of setting the mechanical stops (adjusting screws) on the specific gravities of the process. Then, these

adjusting screws are very helpful to perform a dry calibration (without fluid).
The two adjusting screws (114) are located on the sides of the case and are closed by two 1/8” NPT plugs (115). They are

adjusted at factory if the specific gravity meter has been calibrated upon displacer type used.

Open the access plug (107) on the right side of the case to look at the simulation mechanism. Remove plug (190) and the

two 1/8” NPT plugs (115). Use a 5 mm hex wrench.

Through this hole, to define REF L and REF H, use your finger to move the flexure (59) in the direction of the torque tube

until the flexure touches the adjusting screw post (114). While maintaining contact, slide the flexure left or right along the

surface of the screw post (Figure 18).

Perform the two adjusting screws (114) setting by reading the specific gravity value indicated by the specific gravity meter

through VIEW DATA menu and SPECIFIC GRAVITY METER sub-menu.

Enter VIEW DATA menu and SPECIFIC GRAVITY METER sub-menu.

OW LEVEL REFERENCE

[ZERO]

e1.

Liquid application

Press the flexure (59) against the adjusting screw shoulder (114), which corresponds to the low level (opposite side to

the displacer). While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays

the specific gravity value 0.0.

e2.

Interface application:

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.

CAUTION:

This procedure is only possible if the [SG METER] function has been calibrated.

Setting of adjusting screws

CAUTION:

Specific gravity value refresh requires exiting and entering again the SPECIFIC GRAVITY METER sub-menu.
