4.2.4 Inserting a cell

Inserting a cell with barcode starts the measurement; with methods without
barcode you have to select the method manually.
Line mark
inner
turn-up lid
If the inner turn-up lid is opened too wide, a message prompts
you to close the inner turn-up lid.
The AutoSelector, which is included in the test sets for rectangular cells, has
on one side a bar code encoding a method number. When the AutoSelector
is inserted in the round cell shaft, the bar code is automatically read and the
relevant method selected by the photometer. User-defined methods and
reagent-free methods normally do not have an AutoSelector and therefore,
no automatic method recognition. In this case, select the method manually
and then insert the cell.

2 Close the inner turn-up lid.
3 Insert the barcoded round cell in
the round cell shaft so it touches
the bottom. When doing so, align
the line mark with the notch at the
front of the round cell shaft.
The photometer selects the
method based on the bar code
and automatically starts measure-
ment.
With cells without barcode: Select
the method manually in the instru-
ment.
Close the inner turn-up lid.
Insert the round cell in the round
cell shaft so that it touches the bot-
tom.
