Here you can also select whether to start again with the first sample after a complete run through the sample
plate.
The plate of the sample changer has 50 positions, whereby the first position is marked 0. This position is
reserved for the 0 – Vial Thus, up to 49 samples can be measured by means of the changer. The procedure is
completely automated. Depending on the setting (0 – Vial interval), the 0 – Vial is retrieved from the 0 position
and placed in the oven before the actual sample measurement. After the start conditions have been met, the
conditioning phase is completed, the 0 – Vial is transported back into the changer and then the sample vial of the
corresponding position is placed in the oven.
Selection between pump (ambient air) or gas (nitrogen).
Setting the working temperature of the oven.
When the automatic fan is switched on, an additional fan switches on to
accelerate cooling processes.
