Parameter
Range; Default value / Meaning
Auto.samples = on
At the start of every determination, the data in the top
line on the "SAMPLES" page are transferred to the 1
st
sample data line on the "MONITORING" page and
used for the determination.
With methods for the 695 Autosampler with preparation
blocks
(PREP...PREP)
, the sample data of the sample
in question are already transferred during the prepara-
tion time to the 2
nd
sample data line on the
"MONITORING" page. On completion of the preceding
determination, these data are transferred to the 1
st
sample data line.
Auto.samples = off
The data of the two sample data lines on the "MONI-
TORING" page are used for every determination. If
data have been entered in the 2
nd
sample data line,
these are transferred to the 1
st
line for the next deter-
mination; if the second line is blank, the data in the 1
st
line are retained.
The 695 Autosampler processes the samples in se-
quence. If a position number is entered in the sample
data line, a start is made at this rack position (with no
entry, start at 1
st
position). If A-instructions (e.g.
F>A
)
are used in the program, every 2
nd
position is defined
as a sample vessel. During the series determination,
the position number of the current sample is shown in
the parameter
Pos.
on the 1
st
sample data line.
In work with
Auto.batch = on
, the volume book-
keeping is not automatically reset to 0 on completion of
the program. If this is desired, the instruction
RINSE
must be inserted before the end of the program.
off
The automatic processing of sample series is switched
off, when the
determination is performed. The data of the two sam-
ple data lines on the "MONITORING" page are used. If
data have been entered in the 2
nd
line, these are
transferred to the 1
st
line for the next determination; if
the second line is blank, the data in the 1
st
line are re-
tained. If this is also blank, the error message
Missing
sample
appears.
reset
The sample counter is reset to 0.
