NO  If a sampler is used with the BioTector, SAMPLER is
programmed (YES).
programmable Sampler time will be displayed automatically in
the Sample Pump menu above.
 In multi-stream systems, CONTROL determines the multi-stream
BIOTECTOR
valve sequence to be controlled by either BIOTECTOR, or by an
EXTERNAL device, or by external STREAM INPUT signals.
 If the CONTROL is programmed as EXTERNAL, then both multi-
stream valve sequence and operation ranges have to be
controlled by an external device.
 If the CONTROL is programmed as STREAM INPUT, then the
multi-stream valve sequence is controlled automatically by the
Stream Input signals sent from an external device. For further
details, see information sheet "O019. BioTector Remote Control
Options and Operation", which is available in the MMC/SD card
shipped with the BioTector.
 START-UP RANGE (3 by default) defines the range BioTector
3
will use at the first reaction it starts up with.
 When the COTROL above is programmed as BIOTECTOR in
multi-stream systems, this function is automatically hidden by
the system, if the first RANGE setting for a particular STREAM is
not programmed as AUTO below.
 If RANGE LOCKED (NO by default) is programmed as YES,
NO
BioTector locks the operation range at the defined RANGE
above. In other words, the automatic range change function is
disabled with the YES setting.
 In multi-stream systems, if none of the RANGE setting for
stream sequence below is programmed as AUTO, this function
is automatically hidden by the system.
3  PROGRAMMED STREAMS displays the number of streams
installed and programmed in Output Devices menu.
 If the CONTROL is programmed as BIOTECTOR, the multi-
RANGE 3
RANGE 3
stream valve sequence operates according to the STREAM and
RANGE 3
RANGE settings defined in this menu.
RANGE -
 In STREAM 1 , 2 setting, the first setting "1" represents the multi-
............... ...
stream valve number (e.g. Stream Valve 1), and the second
setting "2" represents the number of reactions to be carried out
at this stream before switching to the next stream.
 RANGE defines the operation range for each stream. In a multi-
stream system, the ranges are locked to Range 3 by default in
the factory. It is recommended to lock each stream to a
particular range (e.g. 1, 2 or 3), which is appropriate to the
concentration levels of the sample, in multi-stream systems.
 When a specific stream is programmed as "- , - - -, RANGE -",
the analysis on that stream does not take place.
 The AUTO (AUTOMATIC) range change function is disabled in
multi-stream systems by default. If it is necessary to run any of
the streams with AUTO range change function, please contact
your local distributor or the manufacturer. When AUTO range
change function is used, a minimum of five analysis reactions is
recommended as BioTector needs to find the optimum operation
range automatically. Therefore, depending on the system
response, it may be necessary to discard the first two or three
analysis results, when the AUTO range change function is
selected for a specific stream.
