5.1 Accessing the weighing chamber

To access the weighing chamber, use the handle of the left or
right tunnel to slide it towards the left or right, respectively.

5.2 Loading the racks with sample vessels

Each numbered position on the racks can be used for dosing. Use the appropriate adapter for your sample
vessel to ensure stability. Do not use sample vessels without adapters. Do not leave empty adapters on the
racks.
1 Use the handle to open the right or left side tunnel (1).
2 Remove the rack (2) accessible through the tunnel
opening.
3 Unload the sample vessels from the rack, if applicable.
4 Load the rack with up to five sample vessels and
adapters (if applicable).
Note
For sample vessels of diameter larger than 31.5 mm, fill
only every second position of the rack.
5 Install the rack at the right position on the drive ring.
Note
To properly identify the sample vessels on the terminal, make sure that the numbering on the racks corre-
sponds to the numbering on the drive ring.
Note
For sample vessels of diameter larger than 31.5 mm, lift the adapter from the neighboring rack while
loading the racks on the drive ring, if necessary.
6 Make sure that the rack is leveled.
7 Use the user interface to move the drive ring toward the left or right.
8 Repeat steps 2 to 7 until all the desired racks are installed in the sample changer.
Note
If a sample position contains no sample vessel, the dosing sequence will skip this position and move to
the next sample vessel.
