TIP
Keep the black transport plastic plugs for later. They can be used as an injection
adapter tool to widen the tips of the adapters in case of leaks.

Mounting the Luer injection adapters
3. Carefully insert the injection adapters into the openings of the adapter
holding plate on the right side of the instrument (see Fig. 7 - 1).
4. With moderate force, push the adapters towards the holding plate.
5. Insert the screws through the bore holes of the adapters and screw them
cautiously into the adapter holding plate until some resistance against further
turning can be felt.

Checking for Leak Tightness
1. Close one adapter tightly with a male Luer plug.
2. Fill air under moderate pressure through the other adapter using a plastic
syringe from the accessory box and wait for a few seconds.
3. Release the plunger of the syringe.
If the connections are tight, the plunger of the syringe will be slowly pushed
back by the pressure in the measuring cell.
CAUTION
If the screw for fastening the adapter is screwed in too tightly, the density
measuring cell may be damaged. Harmful liquids leaking from the instrument
may cause injuries.
•
Tighten the screw until some resistance against further turning can be felt
and then stop to tighten the screw. The gap left between the holding plate
and the adapter where the thread of the screw becomes visible is approx.
3 to 8 mm (approx. 0.12 to 0.31 in).
