1 Introduction
1.1 The 814 USB Sample Processor in the Titrando sys-
tem
The 814 USB Sample Processor is a component of the modular Titrando
system. Operation is carried out either by a Touch Control with a touch-
sensitive screen ("stand-alone titrator") or by a computer with a corre-
sponding software.
A Titrando system can contain numerous, various kinds of instruments.
The following figure provides an overview of the peripheral devices you
can connect to the 814 USB Sample Processor.

2￭￭￭￭￭￭￭￭ 814 USB Sample Processor
Up to three control instruments (Titrando, Dosing Interface, USB Sample
Processor, etc.) can be controlled via USB connection during operation
with the 900 Touch Control. If the tiamo software is used, then there is no
limit to the number of control instruments that can be used to extend the
system.
Updating the device software is described in the manual for the Touch
Control or in the online help for the tiamo software.
1.2 Instrument description
The 814 USB Sample Processor is a versatile instrument. It has been
designed exclusively for usage in factories, as long as ambient conditions
(see chapter 7.5, page 43) are fulfilled, and laboratories and thereby cov-
ers a wide range of applications.
Thanks to the integration of high-performance USB interfaces, it can be
incorporated seamlessly into a Metrohm Titrando system. The versatile
communications options of the Titrando system (Remote Box, LIMS link,
etc.) can thus all be used. Thanks to these abilities, a 814 USB Sample Pro-
cessor is predetermined for all kind of automation tasks in a modern labo-
ratory, especially for highly integrated laboratory data systems.
The user interface of the Touch Control or the tiamo software guarantees
comfortable operation and programming of the 814 USB Sample Pro-
cessor. The comprehensive range of commands and the various configura-
tion possibilities can comfortably and efficiently be used this way. The inte-
gration into the Titrando system also guarantees a 100% conformity of
the complete automation system with the FDA regulations (Food and
Drug Administration), especially with the regulation 21 CFR part 11, elec-
tronic records and signatures.
There are exchangeable standard sample racks available for many vessel
dimensions. Freely selectable special beaker positions can be defined for
e.g. rinsing or conditioning beakers on every rack.
Customer-specific special racks for individual requirements can be fabrica-
ted upon request.
1.2.1 Model versions

1.2.3 Intended use
The 814 USB Sample Processor is designed for usage as an automation
system in analytical laboratories or in factories that fulfill the specified
ambient conditions (see chapter 7.5, page 43). It is not suitable for
usage in biochemical, biological or medical environments in its basic
equipment version.
This instrument is suitable for processing chemicals and flammable sam-
ples. Usage of the 814 USB Sample Processor therefore requires the user
to have basic knowledge and experience in handling toxic and caustic
substances. Knowledge with respect to the application of the fire preven-
tion measures prescribed for laboratories is also mandatory.

1.4.1 General notes on safety
WARNING
Operate this instrument only according to the information contained in
this documentation.
This instrument left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the
instrument, the following instructions must be observed carefully.
1.4.2 Electrical safety
The electrical safety when working with the instrument is ensured as part
of the international standard IEC 61010.
WARNING
Only personnel qualified by Metrohm are authorized to carry out service
work on electronic components.

WARNING
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.
Supply voltage
WARNING
An incorrect supply voltage can damage the instrument.
Only operate this instrument with a supply voltage specified for it (see
rear panel of the instrument).
Protection against electrostatic charges
WARNING
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Do not fail to pull the power cord out of the power socket before you
set up or disconnect electrical plug connections at the rear of the
instrument.
1.4.3 Tubing and capillary connections
CAUTION
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing con-
nections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are manda-
tory.

1.4.4 Personnel safety
WARNING
Wear protective goggles and working clothes suitable for laboratory
work while operating the 814 USB Sample Processor. It is also advisable
to wear gloves when caustic liquids are used or in situations where
glass vessels could break.
WARNING
Always install the safety shield supplied with the equipment before
using the instrument for the first time. Pre-installed safety shields are
not allowed to be removed.
The 814 USB Sample Processor may not be operated without a safety
shield!
WARNING
Personnel are not permitted to reach into the working area of the
instrument while operations are running!
A considerable risk of injury exists for the user.
WARNING
In the event of a possible blockage of a drive, the power plug must be
pulled out of the socket immediately. Do not attempt to free jammed
sample vessels or other parts while the device is switched on. Blockages
can only be cleared when the instrument is in a voltage-free status; this
action generally involves a considerable risk of injury.
WARNING
The 814 USB Sample Processor is not suitable for utilization in bio-
chemical, biological or medical environments in its basic equipment ver-
sion.
Appropriate protective measures must be implemented in the event
that potentially infectious samples or reagents are being processed.
