Placing the Apparatus into operation
Set up the Blaine Apparatus on a surface that is level, that is not subject to vibrations, and
that can sufficiently support the weight of the apparatus. The permissible ambient condi-
tions are in accordance with standard laboratory conditions as set forth in EN 196
Use the injection with hose, supplied by the Manufacturer, to pour the filling oil into the U-
shaped tube. Before filling the tube, make sure that it is clean and dry.
Use the injection unit to remove liquid from the bottle in which it is delivered. Insert the end
of the injector hose into the U-shaped tube. Make sure that you can see the hose in the
U-shaped tube, and also make sure that the manometer liquid actually flows into the tube.
Fill the liquid up to the lowest mark.
If the liquid is filled above the proper filling height, use the injector unit to remove the
surplus oil.
Grease the cone slightly with the delivered grease.
Caution
The manometer liquid is a min-
eral hydraulic oil. This liquid can
cause serious health.
Do not pour out the oil throuht
the cone.
It could go to a valve and could
cause damage.
Note
Fill the oil slowly and carefully,
since the levels of the oil will ad-
just very slowly.
If exceed the mark then use the
injection with tube to suck out the
surplus oil.
At regular intervals, the liquid
level must be checked. The fluid
level must be equal to the mark.
