Analogue Inputs
The analogue input cables are intended for connection between the
DataStream and any detector or other voltage source with an output
range of ±1V or smaller. Connect the red wire to the positive output
terminal and the black wire to the negative output terminal of the source.
Do not connect the screen of the cable to the source.
The 3-pin connector on the analogue cable should be inserted into the
desired channel input socket on the DataStream.
Unused channels can be left unconnected.
Connections

RS232 Serial Cable
Connect the serial cable from the 9-pin RS232 socket on the DataStream
to a free serial port on the PC on which the Cirrus software has been
installed.
AUX I/O
This connector provides external channel start facilities and contact-
closure relay outputs:

Connections

To trigger a channel using an external contact closure, simply connect one
side of the switch to one of the GND pins and the other side to the desired
START CHANNEL pin. Data collection will start as soon as the switch is
closed. Alternatively a TTL-compatible logic LOW signal can be used to
trigger a channel

1 Introduction to the DataStream
Connections

The differential pressure transducer monitors the pressure drop across the bridge,
ΔP, and the inlet pressure transducer measures the pressure drop through the
bridge, Pi. When the sample is introduced across capillary 4 (C4) of the bridge, an
imbalance is caused due to the hold-up columns. This change in pressure, ΔPis
proportional to the specific viscosity, ηsp, according to the following equation.
Where ΔPis the differential pressure across the bridge and
Pi
,is the pressure of the
flow through the capillary bridge. The instrument makes a true differential
measurement directly, making it very sensitive to dilute solution viscosity
measurements.
Using the Module
Agilent 1260 Infinity II DataStream User Manual
Power Switch
The power switch is located on the power inlet situated on the rear panel
of the instrument.
Press the ‘I’ symbol to switch ON or the ‘O’ symbol to switch OFF.
Channel Start Buttons
A data acquisition run on any channel may be started manually by
pressing the associated channel start button after the DataStream has
been initialised by the Cirrus software.
Power-Up Sequence
When the instrument is turned on the status LED on the front panel
will briefly become green. It will then go amber whilst the instrument
performs a range of internal self-test and calibration tasks. These can
take up to 1 minute after which the status LED will become green
again, indicating that the instrument is ready to collect data. If an
error occurs during the internal tests the LED will remain amber and
the 4 channel run LEDs will flash. If this happens, cycle the power to
retry the internal tests.

Site Requirements
Site Requirements
A suitable environment is important to ensure optimal performance of the
instrument.
Power Considerations
Check the operating voltage of your instrument on the IEC inlet fuse
holder on rear of unit.
WARNING
Hazard of electrical shock or damage of your instrumentation
can result, if the devices are connected to a line voltage higher than specified.
➔Connect your instrument to the specified line voltage only.
WARNING
The module is partially energized when switched off, as long as the power cord is
plugged in.
Repair work at the module can lead to personal injuries, e.g. electrical shock, when
the cover is opened and the module is connected to power.
➔Always unplug the power cable before opening the cover.
➔Do not connect the power cable to the instrument while the covers are removed.
WARNING
Inaccessible power plug.
In case of emergency it must be possible to disconnect the instrument from the
power line at any time.
➔Make sure the power connector of the instrument can be easily reached and
unplugged.
➔Provide sufficient space behind the power socket of the instrument to unplug the
cable.

Power Cords
Country- specific power cords are available for the module. The female end
of all power cords is identical. It plugs into the power- input socket at the
rear. The male end of each power cord is different and designed to match
the wall socket of a particular country or region.
Agilent makes sure that your instrument is shipped with the power cord
that is suitable for your particular country or region.
WARNING
Absence of ground connection
The absence of ground connection can lead to electric shock or short circuit.
➔Never operate your instrumentation from a power outlet that has no ground
connection.
WARNING
Unintended use of supplied power cords
Using power cords for unintended purposes can lead to personal injury or damage of
electronic equipment.
➔Never use a power cord other than the one that Agilent shipped with this
instrument.
➔Never use the power cords that Agilent Technologies supplies with this instrument
for any other equipment.
➔Never use cables other than the ones supplied by Agilent Technologies to ensure
proper functionality and compliance with safety or EMC regulations.
WARNING
Power cords
Solvents may damage electrical cables.
➔Prevent electrical cables from getting in contact with solvents.
➔Exchange electrical cables after contact with solvents.

Bench Space
The module dimensions and weight (see Table 1) allow you to place the
module on almost any desk or laboratory bench. Ensure that the power
switch & appliance power connector situated at the rear of the unit remain
easily accessible at all times.
Environment
Your module will work within the specifications at
ambient temperatures and relative humidity described in
Table 1.
Avoid exposure to direct sunlight and other sources of
temperature fluctuations (e.g. draughts).
Do not allow the unit to come into contact with hazardous or
dangerous chemicals.
Do not use this equipment in hazardous atmospheres or with
hazardous materials for which it was not designed.
NOTE This module is designed to operate in a typical electromagnetic environment, i.e. where RF
transmitters such as mobile telephones may not be used in close proximity.
