On beaker error
Behavior with missing sample beaker
MOVE_S | display
If a beaker sensor finds that a sample beaker is missing
then this instruction can be used to carry out two sub-
sequent actions automatically:
display An error message is displayed and
the operator must take action. The
instrument moves to the
'hold' condit-
ion and the changer can be operated
manually.
MOVE_S The previous MOVE command is
carried out again; the changer "looks
for" the next sample beaker. A pre-
vious
SAMPLE command will be
taken into account, i.e. with
'SAMPLE +2' the next but one sample
beaker will be moved to.
SAMPLE
Alteration of the run variable SAMPLE
The run variable SAMPLE is used as a sample counter during the process-
ing of a series of samples. It always refers to the current sample position in
the sample rack. It can be set manually with the
'Sample pos.' entry on the
Titroprocessor main page. However, a SAMPLE command will overwrite
this entry. When a sample has been processed the run variable will be
automatically increased by
1 so that in a method the next sample beaker
can always be brought into position with the command MOVE_S.
This run variable, and therefore the particular valid sample position, can be
specifically altered with this
SAMPLE command. If the SAMPLE command
is used in a method then the automatic SAMPLE variable increase is
switched off.

Function
Type of SAMPLE variable alteration
+ | – | =
The SAMPLE variable can be increased ( '
+
') or de-
creased ( '–'). Allocation of a specific value ('=') (setting
a particular sample position) only makes sense in an
(
OMOVE) start sequence.
