The PROGRAM OPTIONS are used to define the settings with which
programs are executed. By pressing a button you can modify the
corresponding value; the current setting is displayed next to the
button (
Fig. 80 ).
STATION SEQUENCE:
Here you can choose between two modes for controlling the se-
quence of ethanol bottles:
Concentration and Auto by RMS
In Auto by RMS mode, the order is controlled by the current RMS
values, i.e. the threshold values entered in the reagent status for
cassettes, cycles or days are used.
Press STATION SEQUENCE to switch to another mode. An instruc-
tion message appears (
Fig. 81 ), which lists the steps the user is
required to carry out so that the instrument will operate without
errors in the new mode. This message must be confirmed with YES;
the system then switches into the newly selected mode. The active
mode is then displayed next to the STATION SEQUENCE button.
In CONCENTRATION mode, ethanol rotation and automatic xylene
replacement are used.
This means that the quantities with which the stations are to be
filled with reagents have been precisely preset. If the RTU-bottles
are not filled according to specification, it is not possible to start an
infiltration program.
The measured ethanol value is compared to the set threshold value
and initiates the exchange of ethanols (see also
Chapter 5.2.5 ).
