• Setup: see paragraph 4.2 “Setup”;
Eco Savings: used to set the stand by parameters (see paragraph 7.6.2 “Eco Savings”). Tap “Exit”
to exit from the “RUN: SETTINGS” screen and return to the home screen.
7.6.1 Change tray/rack type
This function is used to change the rack type to be used during the run.
This operation has to be performed when the autosampler is installed on a GC. Access sequence:
RUN>SETTINGS>TRAY TYPE
In the “TRAY TYPE” screen you will see a list of the racks stored in the unit memory.
The racks are described by the number of vial positions, dimension of sample vials and needle draw
depth inside the sample vial (example: 42-10ml-25mm). Select the rack type to install. If the rack is
not shown in the tray list it has to be created (see paragraph 4.2.1.5 “Alignment: Tray Install”).
A wizard for mounting the new rack/s starts. Follow it:
• if necessary, remove the old rack (do not do this during autosampler installation);
• install the new rack (see paragraph 7.6.1.1 “Rack mounting” for mounting the rack in the
correct way)
• Place a vial in the indicated position. Tap “Continue” to go on, otherwise “ABORT”;
• The unit will ask to run the touch procedure. This can be run (recommended) or skipped.
Warning
If the dimension of the sample vials has been modified (6ml-10ml-20ml), the user has to
install or remove (if present) the spacers using the suitable tweezers (Spacers kits are sold
as options, see paragraph 1.7.2 “Options“). In particular for HT2000H/HT2000HT, the spacers
must be installed in the six positions of the oven and for HT2100H, the spacers must be
installed in the 14 positions of the sample rack and in the single position of the oven.
Select “Exit” to exit from the “TRAY TYPE” screen.
7.6.1.1 Rack mounting
Place the rack in the tray paying attention that the letter A has to face toward the operator (see
figure below).
