great force and at considerable speed. Moreover, these instruments often handle
toxic or other chemically and biologically hazardous substances which require
adequate safety measures.
As a consequence, the safety of users and personnel can only be ensured if the
safety instructions in this manual and the relevant hardware and software
manuals of the instruments on which the Gravimetric Test is run, are strictly
observed and followed.
Therefore, the relevant manuals must always be available to all persons
performing the tasks described herein.
2.1 User Qualification

General Description
3.1.1 Balance Kit
The following table lists the parts the Balance Kit consists of. Also refer to
Fig. 3-1, 3-1.
Ordering the
Balance Kit
The Balance Kit (or certain parts of it) can be ordered from Tecan or via a local
Tecan representative. For more details see section
7 “Spare Parts and Accessories”, 7-1.
Note: The Balance Kit does not comprise the Weighing Module (weighing cell +
control unit), nor are the connection cable and other accessories part of the kit.
These items must be ordered directly from Mettler Toledo AG (see next section).
Tab. 3-1 Parts of the Balance Kit

Figure
Quantitiy Designation Explanation
A1 Draft shield Protects the vessel (C) with the liquid to be weighed
from air drafts.
B1 Evaporation
ring
This ring is placed on the Weighing Cell (H) as shown
in the figure. It contains a groove that can be filled with
distilled or de-ionized water. During operation, part of
this liquid evaporates and thus increases the air
humidity under the draft shield. This, in turn, has the
effect that less liquid evaporates from the vessel dur-
ing the Gravimetric Test. In this way, the accuracy of
the test results is increased indirectly.
C2 Vessel Contains the liquid to be weighed during the Gravimet-
ric Test. The vessel rests on the weighing pan (E).
D1 Centering ring Holds the evaporation ring (B) in place
F1 Adapter plate Plate with two handles and positioning slots that can
be placed in the appropriate grid position on the work-
table. It also has four positioning holes that allow posi-
tioning the Weighing Cell (H) properly on the plate.
G4 Foot + counter-
nut
The four feet are standard knurled screws with a plas-
tic head. They are screwed to the bottom of the Weigh-
ing Cell (H) and can be used to level out the Weighing
Cell. The counternuts serves for securing the feet.

3.1.2 SAG 285/01
Brief
Description
The SAG 285/01 is a product of Mettler Toledo AG and has been available since
January 2004. This SAG 285/01 consists of a Weighing Cell (H) and a separate
Control Unit (J) that are interconnected with a cable. Thanks to this separation a
higher precision and stability can be attained.
The SAG 285/01 is a substitute for the predecessor model AG 285 which
incorporated the weighing cell, the display and the operating and control elements
in one unit. Note, that this model is no longer available.
The following two tables list the parts that must be ordered directly from Mettler
Toledo:
Tab. 3-2, 3-3 lists the parts the SAG 285/01consists of.

4.1.2 Unpacking and Inspection
1Unpack the Balance Kit and the SAG 285/01.
2Ensure that no parts are missing or damaged.
3Check whether the voltage range of the SAG 285/01 supply unit corresponds
with the local mains voltage.
4Contact the supplier of the SAG/01 or your nearest Tecan representative if
any parts are missing or damaged.
4.1.3 For Your Safety
WARNING
Damage to the system and danger of electric shock.
Always switch the instrument and the computer off before making any electric
connections or opening the instrument’s access door.
4.1.4 Preparing the Weighing Cell
Also see Fig. 4-1 , 4-1.
4Carefully place the Weighing Cell onto the adapter plate with the feet inserted
into the corresponding positioning holes.
5Check whether the Weighing Cell is seated properly on the adapter plate and
does not wobble. If necessary adjust the cell by turning the feet until the cell is
level and stable.
6Carefully tighten the counternuts to secure the feet when done.
7Place the centering ring (D) on the cell and insert the cone of the weighing pan
(E) into the corresponding hole as shown in the figure.
To prepare the Weighing Cell:
1Screw the counternuts on the
screw bolts of the feet (F)
down until the stop.
2Screw the feet (F) into the
corresponding mounting
holes at the bottom of the
Weighing Cell (H).
3Place the adapter plate (G)
on a the worktable in the grid
position where you want to
perform the Gravimentric test
later.
